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


Though there are perhaps better transistor amps, but Pass seems to be an excellent choice for many.
What is your experience with them, if you could elaborate ? Integrateds as well.

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...

Perhaps I have the wrong model but I thought the Coda Continuum 8 amplifier is a high biased A/AB amplifier not 150 watts pure class A. With regard to whether the X series or XA series is "better," I assumed the XA would be preferred but when I talked to Kent at Pass Labs he steered me toward the X series for my speakers (Thiels)...he said the X series would be a better match. So I was prepared to spend significantly more money but I ended up with a X150.8 and its one of the most harmonically rich and detailed amplifiers I’ve ever heard. So much so I was thinking about trying one of their preamps.
