Schiit Audio. I bought their little headphone amp a couple of years back for my son. So completely unlistenable. I don’t know if I got a bad one or what, but it should have never left their grounds. It just really turned me off of that brand.Same experience for me.... Unlistenable....It takes 5 seconds....I selll it the day after and never look back to this brand....
I imagine that their newer products were better but i was never tempted to verify, especially after trying another cheap amplifier that crush them at the same price....
