    video enhancer, and two -buss switching(separate "Record" and "View" selectors). TheC -90's unique system remote -control unitfeatures volume adjustment, input sourceselection, and control of audio and videoinput devices such as Pioneer's"Slr compat-ible VCRs, CDs, LaserVision players andcassette decks.

    The M-90 is a superb high -power stereoamplifier, utilizing dual -mono construction.It is conservatively rated at 200 W/CH into8 ohms' and delivers 800 W/CH of dynamicpower at 2 ohms? The wide dynamic range ofdigital sources can now be reproduced effort-lessly, with any loudspeakers. The M -90's highcurrent capacity of 47 amps can handle thechallenge of the most complex speaker loads.To further enhance S/N ratio and channelseparation, relay -operated electronic switchesand a long shaft volume control keep the lengthof signal paths down to a minimum. Why in-clude a high quality volume control on a poweramp? Simple. To pursue the straight -wire-with -gain philosophy when using a CD playerconnected directly. Pure sound, redefined.

    The exquisite finish of the M-90 and C-90reflects their quality. Elegant rosewood sidepanels and front panels with a deep hand-brushed lacquer finish emphasize the care ofcraftsmanship we've lavished on these twocomponents. The Pioneer C-90 Preamp andM-90 Power Amp. Evolutionary? Hardly.Revolutionary? Most definitely.

    Matthew Polk has, during the last year,continued to push his creative genius to thelimit in order to develop a smaller, moremoderately priced Signature Edition SDA incor-porating virtually all of the innovations anddesign features of the SRS without significantlycompromising its awesome sonic performance.The extraordinary new SRS 2 is the spectacularlysuccessful result. Music lovers who are priv-ileged to own a pair of either model will shareMatthew Polk's pride every time they sit downand enjoy the unparalleled experience of lis-tening to their favorite music through theseextraordinary loudspeakers, or when theydemonstrate them to their admiring friends.

    FOR UNDER $500 YOU CAN OWN ANAMPLIFIER JUDGED TO HAVE THE EXACT

    SOUND CHARACTERISTICS OF AN ESOTERIC

    $3000 MODEL.

    Bob Carver recently shocked the staid audiophileworld by winning a challenge that no other amplifierdesigner could ever consider.

    The new M -1.0t was judged, in extensive listeningtests by one of America's most respected audio-phile publications, to be the sonic equivalent of aPAIR of legendary, esoteric mono amplifiers whichretail for $3000 each!

    CARVER'S GREAT AMPLIFIER CHALLENGE.Last year. Bob Carver made an audacious offer tothe editors of Stereophile Magazine, one of Ameri-ca's exacting and critical audio publications. Hewould make his forthcoming amplifier design soundexactly like ANY high-priced, esoteric, perfectionistamplifier (or amplifiers) the editors could choose.In just 48 hours. In a hotel room near Stereophile'soffices in New Mexico! As the magazine put it, "lf itwere possible, wouldn't it already have been done?Bob's claim was something we just couldn't passup unchallenged"

    What transpired is now high fidelity history. Fromthe start, the Stereophile evaluation team was skep-tical ("We wanted Bob to fail We wanted to hear adifference") They drove the product of Bob's round-the-clock modifications and their nominees for "bestpower amplifier" with some of the finest componentsin the world. Through reference speakers that arenothing short of awesome. Ultimately, after exhaus-tive listening tests with carefully selected musicranging from chamber to symphonic to high -impactpop that led them to write, each time we'd put theother amplifier in and listen to the same musicalpassage again, and hear exactly the same thing Onthe second day of listening to his final design, we

    (A14TER

    threw in the towel and conceded Bob the boutAccording to the rules... Bob had won.'

    BRAIN CHALLENGES BRAWN. 3elow is aphoto of the 20 -pound, cool -running IV -1.0t. Aboveit are the outlines of the pair of legendary mono

    amplifiers used in the Stereophile challenge. Evenindividually, they can hardly be lifted and demandstringent ventilation requirements. And yet, accord-ing to some of the most discriminating audiophilesin the world, Bob's new design is their sonic equal.

    The M-1.0t's secret is its patented Magnetic FieldCoil. Instead of increasing cost, size and heat outputwith huge storage circuits, Magnetic Field Amplifi-cation delivers its awesome output from this smallbut powerfu component. The result is a design withthe dynamic power to reproduce the leading edgeattacks of musical notes which form the keen edgeof musical reality.

    PO Box 1237 Lynnwood. WA 98046

    A DESIGN FOR THE CHALLENGES OFMODERN MUSIC REPRODUCTION. The M-1.0t'sastor 'shingly high voltage, high current output andexclusive operation features make it perfect for thedemands of compact digital discs, video hi-fi andother wide dynamic range playback media. TheM -1.0t

    Has a continuous FTC sine -wave output con-servatively rated at 2(X) watts per channel. *

    Produces 350-500 watts per channel of RMSpower and 800-1100 watts momentary peak power(depending on impedance).

    Delivers 1000 watts continuous sine wave outputat8 ohms in bridging mode without switching or

    Is capable of handling unintended 1 -ohm speakerloads without shutting down.

    Includes elaborate safeguards including DC Off-set and Short Circuit Power Interrupt protection.

    SHARE THE RESULTS OF VICTORY. We inviteyou to compare the new M -1.0t against any and allcompetition.

    SINCE THE SONIC DIFFERENCES BETWEEN MOST

    good Compact Disc players are almost nil.the significant concern for most of us will behow dependable the machines we buy turnout to be. I could have used some reportsalong these lines before I acquired my lem-on. but in fact, all the reviews of CD players Iever read were favorable and spent moretime rattling off the bells and whistles, withhardly a word about long-term reliability.Now that some of the brands have beenaround for a while, could you report on theirtrack records? That kind of informationmight be hard to come by. but if you coulddo it, you might raise some eyebrows.Mow DerrNarberth,

    See October's "Basically Speaking" for a full treat-ment of this subject. In short, you are right on bothcounts: Information on rehabihty would be tenuseful, but it is ten hard to come by. It'e do not have

    the players we review on hand long enough to deter-

    mine how reliable they are the reports would be ob-

    solete by the time they hit the stands r, and even if we

    did, how would we know in any particular casewhether a failure was the result of a design weakness

    or just a fluke? We would need many samples of

    each model tested. The only other nay we can think

    of to obtain such data would be to sumer dealers and

    repair shops. and given the time required for thatplus our three-month publication lead time, theinformation would be badly' out of date by the time it

    reached print. -Ed.

One correspondent suggeststhat the dearth of Russian composers of thestature of Prokoliev and Shostakovichmeans that the system finally has won. Well.all I can say is that a system that takes thatmany years to win clearly is not trying veryhard.

Surely none are so obtuse as thosewho fail to see that for the average blackSouth African-indeed, for all 24 million ofthem-neither Telarc nor HIGH FIDELITY iswithin reach, to say nothing of liberty andfreedom.Carotid.

    ll'e can't see what harm South African sales ofHIGH FIDELITY (or Telarc recordings, for thatmailer) could do that country's blacks. (Our salesthere are very small, in any event. ).-Ind why is it bad

    for our readers to know that there is strong demandfor Compact Discs in South Africa? ll'e are remind-ed, paradoxically, of a letter we received some time

    back from a reader incensed at our description ofNelson Mandela as a South African nationalist. He

    felt that Mandela was a Communist and a terronstand that we had unwittingly served the cause of So-

    formance has made the greatest strides, asevidenced by Beta Hi-Fi, VHS Hi-Fi, and.more recently, the entirely new 8mm formatwith both AFM and PCM sound recording.More subtle have been the picture improve-ments made possible by Super Beta and HQcircuitry. Digital circuitry has not been a fac-tor in improving actual picture quality:Field -storage techniques have been em-ployed in so-called digital VCRs solely to

    provide jitter -free still frames and slow mo-tion. clearer picture scanning, special ef-fects, and picture -in -picture displays.

    But now NEC, the world's largest pro-ducer of semiconductors, has developed adigital video noise reduction system forVCRs that actually seeks to improve the pic-ture quality of any tape being played. Thetechnique is said to increase the video sig-nal-to-noise ratio by as much as 9 dB (as

    compared to 2 or 3 dB with HQ alone).Video noise manifests itself in three ways: asflecks of spurious color, as graininess in thedark areas of a scene, or as "snow." Since thenoise is random, some of it can be canceled ifsuccessive video fields (two fields equal onepicture "frame") are averaged. The NEC cir-cuit does this by digitizing and temporarilystoring one field, then adding it to the nextand halving their sum (in effect, taking theaverage), creating a single field with as muchas 29 percent less noise (a figure derivedfrom the probability of the two fields cancel-ing some of each other's noise). Each succes-sive original video field is then averaged withthe previously stored notsr-reduced field(which is itself an average). All of this, ofcourse, is happening very rapidly, displayinga picture that is composed entirely of thesenoise -reduced fields. The degree of noisereduction is governed by a feedback loopand can be adjusted to suit the quality of thetape being played (high -quality materialmight actually be compromised if too muchnoise reduction were to be used).

    Two NEC VHS videocassette recordersare the first to get this digital treatment: themonaural DX -1000U and the VHS Hi-FiDX -2000U (pictured). Definition is im-proved by the effects of two HQ circuits:white -clip extension and detail enhance-ment. Although each model has just twovideo heads, the quality of effects like slowmotion and still frame is said to surpass thatof conventional four -head machines-anadded benefit of the digital field -storageprocess. Also, a freeze frame can be takenfrom any off -air broadcast received on theVCR's tuner. Other features common toboth models are a wireless remote controlthat also works with current NEC TV moni-tors. an electronic cable -compatible tuner.and on -screen timer programming. The DX -2000U has an MTS/SAP TV tuner and canrecord and play back both VHS Hi-Fi andDolby linear stereo soundtracks. Price is$700 for the DX -1000U and not yet an-nounced for the DX -2000U.

    The unit contains four amplifiers rated at30 watts (14.8 dBW) per channel (bridge-able to 60 watts, or 17.8 dBW, per channelfor stereo), making it possible to connecttwo pairs of speakers for surround soundwithout using an additional back -channelamplifier. A monaural center -channel out-put can be used to reproduce the dialogue inDolby Surround-encoded movies (a sepa-rate amplifier is needed); a separate sub -woofer output is also provided. In additionto Dolby, there are two surround modes foruse with other stereo sources. Three sets ofvideo connections (one for playback only)and a fourth hookup for an audio tape deckare included. Switching among the sourcesis arranged for easy dubbing. An unusual(and welcome) feature for a component ofthis type is a phono input, although owing toShure's heritage, it seems almost obligatory.

    Other features include a video image en-hancer, a high -frequency noise filter forvideotape hiss, individual volume controlsfor the four channels, and a master volumecontrol. Most functions can be operatedfrom the wireless remote. The AVC-20 inte-grated amplifier is priced at $550 and isavailable from Shure Brothers, Inc., 222Hartrey Ave.. Evanston, III. 60202.

    that's built into a 27 -inch digital set.The Bose system is (-entered on the com-

    pany's "acoustic waveguide" design, whichis basically a small woofer with two different -length tubes (waveguides) attached at eitherend. The tubes are folded so that each end isdirected out the back of the set, and the en-tire assembly fits into the top rear portion ofthe cabinet, making the 'UV no deeper thancompetitive models. The key characteristicsof the waveguide design are high operatingefficiency and extended bass reproductionunusual for such a small enclosure. (See our

    report on the Bose Acoustic Wave MusicSystem its the June 1985 issue.)

    One amplifier powers the driver in thewaveguide, while mid and high frequenciesare reproduced through two front -mounted"twiddlers" (a name coined by Bose forcombination midrange -tweeters). each driv-en by its own amplifier. Loudness compen-sation is achieved by what Bose calls its "dy-namic equalization circuitry." whichautomatically adjusts the bass output tomaintain the same tonal balance at all vol-ume levels. To permit the Bose system's useas a hi-fi sound system. an "audio only"switch disengages the TV picture.

    The set itself rides on a digital chassis,converting incoming video and audio sig-nals to their digital equivalents: an on -boardcomputer then controls the picture -process-ing circuitry and ensures that the set stays upto spec. Naturally, an MTS/SAP decoder ispart of the package. Other features includeon -screen display of remote -controlledffinctions and 178 -channel tuning.

    Lots of com3anies let you run a compo-nent hi-fi system .rom across the room. Someeven let you do it with only one remote con-troller. Sound terrific? That depends ...0f1 howthe components sound.

    At Denon, we believe that superior soundis the only thing that makes high fidelity worththe money. We call this philosophy DesignIntegrity. And it's evident in every new Denonremote cornponert -from the top of the lineyou see here* to our most affordable remotemodels.

    The DCD-110 Compact Disc Player(shown) has already been declared "ReferenceClass" by Germany's Audio and HiF Visionmagazines. In the U.S., Digital Audio pro-claimed, "The Denon engineers who createdthe DCD-1500 should be honored in public:'

    Denon's expertise in making pro digitalrecorders and blank tape is reflected in the newDRM-30HX Cassette Deck. You can see it in thethree -head design. in the super -smooth three -motor transport. A Id in the choice of Dolby' B,C, and HX Pro.

    Thanks to Design Integrity, the DRA-95VRReceiver uses the same Pure Current PowerSupply, Non-NFB circuitry; and MC cartridgeinputs as Denon in-egrated amps. What's more,every Denon receiver provides switchingfacil ties for a VCR, a video disk player and avideo monitor.

    So before you buy components whosemost impressive feature is a remote control, getyourself to a Denon dealer. And listen to theremote control whose most impressive featureis t ie components it controls.

  • To hear why Genesisrecords on Sony digital equipment,play them

    back on a Sony Compact Disc Player.When it comes to capturing the experience of

    live music, no audio equipment delivers the lifelikereproduction of digital audio.

    That's why the only digital recording equipmentchosen by Tony Banks, Phil Collins and MikeRutherford of Genesis is, not surprisingly, theleader in the industry: Sony.

    Not only has Sony led the way in profes-sional digital recording equipment, weinvented the digital audio system for play-back-the compact disc player. Sony alsointroduced the first home, car and portableCD players. And Sony sells more types of compactdisc players than anyone else in the world.

    But whichever Sony Compact Disc Player youchoose, each allows you to hear the music the way theartist originally intended.

    So why not do what Genesis does? Play backthe top -selling compact discs like "InvisibleTouch" the way they were mastered. On

    Sony Digital equipment. You'llfind that when it comes

    to bringing you close tothe music, nothingeven comes close.

    No STOP

    eQUEALING TAPE IS ONEaproblem for which, morethan any other, I wish I couldbe of some help to our readers;frankly, it has me entirely sty-mied. I've experienced it-butnot for many years, though Iwork with all sorts of decks andall sorts of tapes.

    Squealing is a form of R 0 Bscrape flutter. Instead of mov-ing at a constant speed, thetape is slowed by friction,jumps ahead when tension overcomes thefriction, slows when the tension is released,and so on. This not only modulates tonesthat the recorder is trying to record or playbut produces acoustic output directly fromthe site of the friction. The frequency of thesqueal is a function of both the deck and thetape, just as tonearm resonance in turnta-bles is determined by both the arm and thecartridge.

    I've brought up the subject with deck andblank -tape manufacturers. Most don't seemto know what I'm talking about; others ac-knowledge that such a problem could exist,with tape makers citing the deck and deckmakers citing the tape. Usually, the only con-crete advice I turn up is to try a differentbrand of tape (if not another deck).

    Most of those who have written to meabout the problem have done just that.Along the way, they have compiled lists ofthe variety of decks and tape types andbrands used (ranging from well-known,high -quality brands to some that I've neverheard of or would avoid using any way).

    I understand the frustration that thisproblem generates. But while I can empa-thize with it. I can't dispel it beyond citingsome obvious remedies: readjustment of thedeck's tape tensioning, checking the cap-stan(s) for worn bearings or a bent shaft, ex-amining all parts in the tape path (guides,heads, pucks) for signs of wear or misalign-ment, checking the reel- or hub -drive partsfor alignment or friction, and cleaning thedeck.

    AINNO-0111.1f VCRs?

    LETTERS CONTINUE TO ARRIVE ASKING ABOUT

    the potential of Hi-Fi videocassette record-ers for audio -only use. As a reader from Hol-lywood, Maryland, puts it: "We need bettermetering, level controls that are easier to use(larger and visibly calibrated), and easiercueing." And, as he goes on to imply, off -the -tape monitoring during recording.

    Frankly, I don't see much hope of VCR -

    I. 0 N

    based recorders replacingopen -reel home audio decks,though that looked like a fairbet only a few years ago. Thereason is that digital audiotape recorders (using theRDAT format) are close to in -

    t troduction, and that's wherethe manufacturers willing to

    R T go after a new high-per-formance audio format are

    G placing their chips. The stor-age density is far better (two-

    hour RDAT cassettes are even tinier than8mm videocassettes). and the RDAT formatis engineered from the ground up for audio.whereas Hi-Fi VCRs (and the PCM digital -sound option in 8mm video decks) are de-signed with video as the top priority.

    Among other things. that meanscramped and undercalibrated audio con-trols. Even as is, many VCRs are monstrous-ly complicated. I know of one line of modelsthat can't be operated until the owner hasgone through a complex installation ritualthat is difficult for many to understand. Theresult: The decks come back to the companyin droves as "defective." The company inquestion can legitimately point out that themanual gives all of the necessary instruc-tions, so if buyers can't or won't follow thatmuch, the prospect of piling on still morefunctions and controls for audio use is dim.Add to this the fact that the potential marketfor audio -only features is minute comparedwith that for the advanced video capabilities,and you can see why there's little incentivefor designers to compromise good video de-signs by catering to audiophiles. And thatreadily translates into no dollars for the de-velopment of monitoring rotary heads. Withall that's going on already in a Hi-Fi VCRhead assembly, I shudder to think what thestructure would be like with an added set ofplayback heads.

    But monitoring heads aren't as impor-tant with Hi-Fi VCRs as they are with con-ventional audio recorders because whatcomes off the tape has less opportunity todiffer from what's fed to it; and if there is adifference you don't like, there's relativelylittle you can do about it. With conventionalmachines-particularly professional -gradeopen -reel decks-you can tweak bias, re-cording EQ or head azimuth or some com-bination of the three to tailor the sound. Thefrequency modulation system in a Hi-FiVCR doesn't respond the same way to thesefactors. And digital systems (such as RDAT)are virtually unaffected by them.

  • C R OS S T A L KCD OVER 1.11

    I'VE NOTICED THAT SOME (:1) PACKAGES CARRY

    the message that the enclosed disc is limitedby the quality of the original tape from whichit was mastered. Is it safe to assume that if anLP contains a lot of background noise orsounds bad, then the CD version also willsound inferior because it was made from diesame master tape? If so, why can't the tioi.ebe filtered out of the original tape to make abetter -sounding Compact Disc?John Pendiede

    Hawthorne, N.Y.

    It all depends. If the reason on LP sounds bad isthat the original master tape was hissy or poorlyrecorded, the CD version is not going to soundmuch, if any, better. But making a record is a com-

    plicated process: There can be many a slip 'twixttape and disc. In other words, you can take a good

    master tape and make mediocre records. It's evenpossible (though harder) to goof up the CD trans-fer. So the short answer to your first question isthat unless the fault you're hearing is steady, low-level hiss (which most likely is tope hiss from an old

    analog master), you can't be certain that it will beduplicated on CD-or even on a reissue of the LP.

    The answer to your second question is lessequivocal but may change soon. It's very hard with

    current technology to remove preexisting noisewithout taking some of the desired signal along.However, after -the -fact noise reduction schemesbased on digital signal processing are under inten-

    sive development. When such methods becomeavailable, record companies will be able to issueCDs (and LPs, for that matter) from old mastertapes that will sound (at least in terms of noise) asthough they were recorded on modern equipment.

    WHENEVER I BUN' A PRERECORDED TAPE, I DUB

    it onto a Type 4 (metal) blank cassette; I thenstore the original safely away and use thecopy for listening. This keeps the originaltape in mint condition, so that if the dub everwears out or gets damaged. 1 can easily re-place it with a new copy that's just as good.However, a friend tells me that CompactDiscs have greater longevity than cassettetapes, which can wear out and will stick afterbeing stored for a long time. Would it makesense for me to get a CD player and copy thediscs onto cassettes, instead of buying andcopying prerecorded cassettes the way I donow? Which approach will give me the bestsound and greatest longevity?Steven Douglas Taylor

    Norton A.F.R., Calif.

    You will be better off on both counts buying CDsinstead of cassettes. In fact, you probably will beamazed at how much better Compact Discs (andtapes made from them) sound compared to prere-corded tapes, which often are pretty bad sonically.And since Compact Discs do not wear out and only

    rarely sustain permanent damage in normal han-dling, you probably could forgo the hassle of dub-bing to tape every one you buy, unless you makethe tapes primarily for use in a portable or car cas-sette deck.

    E\ l'ERNALLY, THE ONIS-7A11 COMPACT DISC

    player shows its heritage most obvious-ly in its use of well -placed, luxurious -

    feeling slanted -keypad transport controlssimilar to those found on Nakamichi cassettedecks. A 24 -slot programmed -playbackmemory is provided, and the tastefully sim-ple status readout is all of one color (paleyellow -green), not the usual razzle-dazzle.The remote control duplicates every front -panel function except the power switch andthe headphone volume control. The outputpin jacks are gold plated, and a subcode out-put jack is provided. And yes, the playerdoes grant direct access to each track or in-

    dex point on a disc via a numeric keypad. De-spite all this, the Nakamichi OMS-7AI I ismost special where it counts: inside.

    One can get an inkling of what's going onfrom some of the test results. The channelseparation of 133 V, dB at 1 kHz is in itself ex-traordinary, but what is really astounding isthat it is still 116 dB at 20 kHz. Althoughthese figures are far in excess of what is nec-essary for subjectively complete stereo sepa-ration. they speak volumes about the qualityof engineering behind this product: Suchperformance is difficult to achieve even insomething as simple as a preamplifier.

    There's more. The linearity figures(which portray the difference in actual vs. ex-pected output level) are the best we haveever encountered. In fact, Diversified Sci-ence Laboratories couldn't find any errorexcept at the lowest test level ( - 90 dB), andthere it amounted to less than 1 dB. This is

    24 HIGH FIDELITY

  • one player that approaches "the theoreticallimits imposed by the digital system," toquote from a Nakamichi white paper. Thatpaper also goes on to explain some of the de-tails of the OMS-7AII circuitry, which maybe responsible for this exemplary behavior.

    Digital -to -analog conversion, that mostcrucial of processes in a CD player, has ap-parently come under intense engineeringscrutiny at Nakamichi. The OMS-7All con-tains two digital -to -analog converter ICs(DACs), a separate one for each channel,which restore the binary numbers decodedfrom the CD to analog voltages. Most, butnot all. DACs used in CD players generatesmall bursts of noise ("glitches") beforetheir output settles down to the value it issupposed to have according to the binarynumber fed to it. Glitches are commonly re-moved by a sample -and -hold circuit placedat the output of the DAC to store the correctanalog voltage reached after the DAC out-put has stabilized. Nakamichi's designershave opted to eliminate this stage and to tryinstead to reduce glitch generation by ad-justing the timings of the eight most signifi-cant bits (the "leftmost" eight digits in a bi-nary number) of each sample value as itenters the DAC. Two glitch -preventiontrimming adjustments are made on eachconverter: one to optimize performance at IkHz, the other at 10 kHz.

    Nakamichi makes a third adjustment fol-lowing the recommendation of the DACchip's manufacturer (Burr -Brown of Tus-con, Arizona). The particular converter usedin the OMS-7All (the PCM54KP) can betrimmed to a most -significant -bit differen-tial nonlinearity of nearly zero at "bipolarzero," which reduces distortion as a signalcrosses between positive and negative volt-age values. Each of these three adjustmentscan improve measured linearity, though thislast is probably the most important. Also im-proving linearity is the running of the DACsat four times the normal CD sampling rate.They operate at 176.4 kHz to convert theoutputs of the player's four -times oversam-pling digital filters. In any case, Nakamichi'sthree adjustments are three more than mostother CI) player manufacturers make whenusing the same DACs-another example ofthe lengths the company has gone to im-prove player performance.

    As for the other test results, none is lessthan excellent. Frequency response bothwith and without de -emphasis is unusuallyflat, the signal-to-noise ratio is exceptionally

    high. and the channel imbalance (measuredas 0.07 dB) is strikingly small. And the playereasily passed the now somewhat tame tor-ture trials of the Philips error -correction testdisc.

    How much Nakamichi's extra effortshave contributed to the OMS-7A11's soundquality is hard to say. In a single-blind com-parison with another high -quality player. us-ing pink noise and music, we could not heatany difference between the two machines.Output levels were matched to within 0.01volt at I kHz (by means of the other player'svolume control), listening was over head-phones, and music playback was synchro-nized by using pairs of the same discs.

    This is not to say that the Nakamichi nec-essarily sounds the same as all other CDplayers-merely that its sound quality is notunique. Fortunately, that sound is very cleanand smooth: we heard nothing untowardthat could not be attributed to the software.This is to be expected from the player's mea-sured performance. It also comes as no sur-prise that the controls operated smoothly,faultlessly, and with decisive tactile feedbackas each metal pushbutton snapped home un-der our fingers (no cheap plastic parts hereor anywhere else on the player). Our overallimpression-from the sound, the measure-ments, and the feel of the controls-is of en-gineering of the highest quality. Vet that.too, could have been predicted. After all, theOMS-7All is made by Nakamichi.(CONTINUED ON PAGE 2 fi)

    the receiver's own tuner section, a CD (aux)input, a phono section (switchable for usewith either moving -coil or fixed -coil car-tridges), and two audio tape inputs. Whenthe monitor/copy button is off, any input ex-cept those for tape will feed the recordingoutputs; for dubbing from deck to deck, youmust turn the monitor/copy switch on andchoose the source machine at the audio se-lector buttons. As a result, you cannot usethe monitor/copy button for source/tapeswitching during dubbing, although it willserve this function (provided you have athree -head deck) during taping from othersources.

    To simplify operation, Denon has limit-ed the tuner section to two modes: one in-cludes automatic stereo switching (forstereo FM stations received above the stereothreshold), automatic seek of the next "re-ceivable" station when you press the up ordown tuning button, and automatic muting

  • of interstation noise. The other offers monoreception only, manual tuning (100 -MHzhalf -channel steps on FM, 10 -kHz full -chan-nel steps on AM), and no muting (so that youcan listen for signs of life down in the roar).

    There are 16 station presets-each ofwhich will hold one AM or one FM frequen-cy-ranged in two eight -button banks, with ashift button for toggling between them. Thetuner automatically shifts bands if youchoose a memorized AM station whileyou're tuned to the FM band or vice versa. Asignal -strength "meter" consisting of threeLED pairs operates on both bands. Wefound the FM thresholds (28, 3414. and 51dBf) well chosen in that they all lie within therange where antenna rotation is most likelyto be needed.

    The tuner -mode switch is only onemono/stereo option; there is also a front -panel switch that blends channels from anysource. Another simulates stereo frommono sources, though it's specifically in-tended for the audio from mono TV broad-casts or videotapes. Subjectively, it seems todo little more than shift the mono sound to-ward the right speaker, so we were no moreimpressed by it than we usually are by suchstereo -simulation features. Also on the frontpanel is a loudness -compensation knob thatdelivers flat response at its maximum settingand introduces a deepening midband dip(together with some overall attenuation) asit is turned down.

    Further signal manipulation can beadded by removing the pre-out/main-injumpers on the back panel and patching inan outboard processor (an equalizer. ambi-ence -recover device, or whatever). Becauseof the speaker -connector design. we advisetaking care to gel good, solid connections atthe speaker outputs. The antenna inputs for

    300 -ohm FM twinlead and the supplied AMloop are conventional lightweight finger -screw terminals, but we were delighted tofind that Denon also provides a 75 -ohm co-axial F connector, which has become thestandard in the U.S. for coaxial FM and TVleads.

    The supplied RC -95 remote handset du-plicates most of the front -panel controls.One significant difference is in the way thepower switches work. The main chassis'spower switch is marked to indicate that ON isSTANDBY and OFF is just OFF. If you leave thereceiver on STANDBY and turn it off at the re-mote, it will return to the current source andvolume settings when you once again pressthe remote's power switch. But when it hasbeen turned off at the chassis switch, it al-ways reverts to the tuner section (though tothe last -tuned station) and to the minimumvolume setting.

    All such preset controls plus the up anddown tuning buttons are included on the re-mote. but not the tuning -mode button, soyou can't tune manually from the remote un-less you've left the receiver itself in the monomode. Also on the remote are all of thesource selectors (audio and video) and tapemonitor/dub controls of the front panelplus its "muting" (actually, 20 -dB attenua-tion) switch. And the manual says that thecontrol also can be used with Denon cassettedecks and Compact Disc players (except theDCD-1800R). For these purposes. mostcommonly -used options (recording, skip.repeat, programming, pause, and so on) areincluded.

    On Diversified Science Laboratories' testbench, the loudness -compensation and tonecontrols proved relatively gentle in their ac-tion. The treble control itself shelves above10 kHz or so at the extreme settings, deliver-ing about 8 dB of boost or cut in that range;less extreme settings begin shelving at lowerfrequencies-as low as about 500 Hz for a 1 -dB attenuation. The BASS shelves belouabout 100 Hz at any setting. with the samedB or so of maximum boost or cut.

    Turning the LOUDNESS to its minimumsetting attenuates the range near 1 kHz by amaximum of just over 15 dB, the bass below80 dB by no more than about 6 dB, and thetreble above 10 kHz by about 10 to 11 dB.Relative to the I -kHz range, then. maximumcompensation boosts the deep bass by lessthan 10 dB. the extreme treble by about 5dB. The volume control is very unusual, butbeneficially so, in being "linear." (Standardpractice is to taper the control's action sothat a median setting delivers much morethan median level, giving the uninitiated theimpression that the receiver or amplifiermust be very powerful.) It steps in incre-ments of very nearly 2 dB for the most part,though some are closer to I dB.

    No filters are built into the DRA-95VR.What attenuation of infrasonics (from warpsor feedback) it provides is inherent in th
