What are the weak points of Pass amps and pre-amps ?

You can’t spell “Tru-Fi” without “fruit.”  Coincidence?  I think not.

Obligatory relevant thread comment: Pass makes some really good stuff.  

benjie, I see. As I understood so far, only slight negatives can be less than perfect precision, speed, dynamics and resolution. Overall, Pass seems to be an excellent choice for many people. Size can be a problem in smaller rooms but look at some other amps out there.

the new XP-22 has an off switch, not familiar with the new phono stages, and the amps have always had a standby and a separate off switch...
