Anyone have experience with VTV amplifiers?

I had one of their Purifi amps for about a week and returned it. The amp worked, didn't sound bad but I wasn't impressed with the build quality.

Don't send me PM's ask the questions in the open forum. The VTV was a neutral amp with good detail, I liked it. As I said I wasn't impressed with the build quality and I didn't want to bother with modifying.  One thing I really disliked was the power switch on the back, either it ran all the time or I had to get down behind it to turn it off. 

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. 

The XLR pin 1 is wired wrong and there is no mains ground.  Speaker and XLR connections were soldered sloppy.
