@pryso,
I have never had an issue with Belles. They replaced my preamp remote after they discovered a problem with a batch that they got, at no charge.
The main reason I chose them is for the sound they make with my Vandy VLR's. I tried the Atmasphere Class D's, but they just didn't 'sparkle' like the Belles. My Aria Monoblocks and Signature Preamp have never had an issue after 2 years of daily use.
