Anyone have experience with VTV amplifiers?

Unfortunate. These small-time, likely single operator outfits shoot themselves in the foot by not slowing down and doing good work. They could build good reputations, if they sacrificed a little in the speed department, checked their work, made it tidy, accurate. 

Nord too?~! 

Have you any experience with d-sonic? 

The VTV version appears to run at a considerable discount, compared to, for example, the Apollon audio version, which starts at about $2500.00. Nord has a stereo version that starts around $1200, and a true-mono version at about $1800.00. The VTV starts at $900.00, including the stock buffer and then goes up to $1250 and upward. 

I can handle a back power switch; were there any other build quality issues? Did you look inside? Aesthetically, it looks quite attractive...

I'm mostly concerned about the sound quality. Neutral and good detail fit for me. How was the bass, mid-bass response? In all that I read, purifi is praised as (maybe) the best OEM modules. Does it compare to any A/B amps you know?

In what I've read of your experience in another thread, or two, you seemed to back away from class D in favor of A/B. My interest is in higher watts at a good value ratio.
