Gustard X30 disappointment

I did, it was very nice, detailed without being bright, and not even close to being broken in.

I have couple of Gustard DAC products, despite 24/7 usage never experienced any problems.. Build quality and used components are top grade..

Did you try to contact Gustard service / support to report the problem and to get help? 

I did not contact gustard, I contacted the reseller, the unit is on it's way back, will see what happens.

I've tried Gustard a few times over the years. I think I've experienced more problems with them than any other brand I can remember. The sound seems interesting but I never really got to evaluate very long due to problems showing up pretty quickly. Maybe just bad luck on my part?
