Got the Purifi + tube buffer version, Sparkos 2590. Paired with my PS Audio BHK Preamp and KEF LS 50 Metas makes an amazing combo. You get it all with this amp. Smoothness along with clarity without harshness in the bass/mids and highs. Super happy with this amp.

I have really clean sources (DSD, hi-end Vinyl, a top-notch CDT & DACs both in my X8500H(A) and external), I’ve been running the VTV Purifi w/Sparkos 2590s for a year now and I can throw anything at them and they just perform magnificently! Super quite, runs cool, great sonics, no incredible sonics with any speaker I throw at them (Magies, KLH Model 5’s, Warfdales, KEFs! Great sound-stage/imaging, base response, great mids/highs and the tube buffer just smooths everything without affecting clarity. Crystal Clear! Everything said above and then some – Just WOW! Get this amp, you will never look back! Warren (the owner) is the best and very approachable and helpful. Thank you.

Amazing amp, I got the 2 channel Purifi version with tube buffer. Easily as good if not better than amps I’ve had 2-3x the price. Highly recommend, and Warren with his customer service is top notch!

Quietest, most effortless amp I’ve ever heard. Quiet in terms of zero distortion, extremely high signal to noise ratio, zero signal alteration. Just pure music. Late at night, during the quietest hours of the 24 hour period, I even held my ear to the speaker with no music playing, and could hear zero hiss. This amp is scary good. It’s a keeper.
Another reviewer mentioned that it competes with FET amps many times the cost. I would agree. And it always runs cool. FET amps you can toast bread on top even when they are not playing music.
The cabinet is of exceptional quality and comprises most of the 15 pounds of weight. Two suggestions for improvement 1) the speaker terminals are mounted just above the balanced inputs. If you have extra stiff high quality speaker cable spades, it’s difficult to attach them when the balanced cables are plugged in. With ample real estate on the rear panel why not space them out more. 2) My preamp does not have a 12v trigger output so I did not order that upgrade for this amp. The Teac UD-505 DAC/ Preamp times out and powers down when there is no music signal for a 10 minute stretch. Most modern active speakers behave the same way. Perhaps a timer option should be offered for the VTV line of amplifiers.
