had the same "problem" as peterayer, which i covered in my review in positive feedback. best solution: buy the biggest XA you can afford...and maybe you cannot. they're fabulous amps. (id own them if the heat of the larger amps weren't prohibitive in my small room in texas)
Pass X vs XA amps sound quality in class A range
If you are one of those lucky enough and has the means to upgrade from the X (or X.5) to the XA (or XA.5) Pass labs amps, is there enough of SQ differences in low power ranges, say between 5-25W, where they all perform in class A mode, supposedly. Thanks for any insight!
