Thank you for initiating this thread. I am interested in the VTV class-D amplifiers (Probably the Purifi Eval-1) and wanted to see whether you had any further comparisons with your McCormack DNA-.5? I owned a DNA-1 in the past, and thought that it was a "muscular" and neutral sounding amplifier. Is the sound of your VTV amplifier comparable in soundstage to the McCormack? I currently have an Audio Research D130 with a Schiit Freya+ which I run in tube mode for critical listening. I'm hoping to gain a little more "omph" for my Magnepan LRS and Proac 2.5s.
My new VTV Audio Class D amp arrived today
I ordered the amp from Warren with the Purifi module and the Sparkos ss3602 op amp, the latter chosen for its somewhat more relaxed sonic presentation compared to the other op amps that VTV offers. Right out of the box, it strikes me as quite musical, without any noticeable harshness, although few inner details of the music are so far revealed. It is dead quiet, as expected. So with my initial favorable impressions, I will report back after it has 100 hours of run-in to comment on its SQ.
