My new VTV Audio Class D amp arrived today

rtorchia,
Good for you, I hope you enjoy it.  I haven't swapped my McCormack SS amp in place of the VTV amp yet, but I did with my Don Sachs KT88 tube amp.  The VTV is a very neutral sounding amp, while the Sachs amp is emblematic of the very best tube amplification, of which everyone knows the characteristics they have.  I enjoy them both very much and don't need to chose one over the other.  However, in the blistering hot summer here in the Central Valley of California, the VTV amp will stay in the system. 

@rtorchia   Any impressions of the eval 1?

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. 

I sold the McCormack a while ago and it did have a more muscular sound, I'd say, whereas the VTV is just amazingly neutral with a huge soundstage and not a bit of harshness.  I don't sense that the VTV is more powerful than the McCormack and perhaps a bit less impactful.   The McCormack has "bigger balls" than the VTV amp, but am not sure it is overall as well balanced.   Both are stellar amps, but the stock .05 is getting long in the tooth with aging caps.  

About a month ago I got a VTV Purifi 2 channel with tube buffer.....super solid amp and definitely massive value for the price.  I found leaving it on all the time worked better than the trigger, as the trigger would always take about 5 seconds until volume came out.  You can leave it on all the time though, barely gets Luke warm after 8 hours straight of use, nothing in standby.  Overall way cleaner sound with low noise base compared to Emotiva or other brands around the same price.  I was powering JTR Triple 8s (98db sensitivity) as well as Focal 91db speakers.  Probably not the best amp for speakers with sensitivity in the mid 80s though.  I'd recommend, Warren at VTV is super helpful and they offer 30 day in home trial.
