Either Jim's friends ears are broke or the x-250 was broke. I had the fpb 200 for a year and when I upgraded to a Pass I was mad at myself for living with that overpriced, unmusical, grainy amp for so long. I dont know why someone would make a bad statement about an amp that they havent even heard, but instead give an opinion about what their "friend" heard. Personally I think this guy has some other motive behind his statement. I mean to compare a Pass x-series amp to bose! ahem... GET REAL. Pass amps on the contrary are one of the few amps that nobody has anything bad to say about. Im done.
