This upper midrange/treble quality brings to mind the Accuphase P-7100. No doubt Vitus offers superior resolution and and—yes!—is the more powerful more dynamic amplifier. But that particular section of the audible range is similar and at first might seem slightly soft and perhaps even sweet. But thanks to excellent resolution, all detail is delivered without homogenization but rather some polishing of edges. I now wondered how this amplifier would fare on bass. Its huge size could have suggested Krell-type grip whilst the paper specs’ 50 watts would bow to a Music Hall A15.2’s 75wpc. But there’s 50 watts at 85kg and then there's 75 watts at 8.5kg. In my obviously subjective opinion the Vitus delivers the same bass quality as the Soulution. This is to say, as much as needed and never separated from the rest but always integral to it.
