Yes it’s true, I sent it back and ordered a PC-Ultra from Eric. Before I started reading the HTF I may have been completely satisfied with the PB10. But not anymore! I guess it was just wishful thinkin’ that the PB10 could serve a room the size or mine (23'x18'x14'vaulted ceiling). Guess I was trying to be “cheap”. It actually sounded very good, very musical, better than my Velo CHT-12, but it just doesn't have the output needed to fill my room. On hard kick drum or bass notes it would distort and then the circuitry kicks in and reduces the output. My Ultra should be in next week. Thanks a lot HTF!
