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.

We really are splitting hairs here.  Yes there are some other real expensive brands that others might prefer over Pass but to these years Pass has always sounded very musical.   They are made in the  USA and the company support is second to none.   No weaknesses  that I can see or hear from Pass.
Gotta laugh at the people saying pass is not good or even bad or not engaging etc etc. Pass make incredible amps. I love my 350.8.

Oh btw @audiotroy is wrong. He said coda no8 does 150 watts class A. Uh no it doesn’t, its 150 watts ab into 8 ohms and only first 18 watts is class a. Please don’t spread misinformation and as an ’audio doctor’ atleast get the basics right.
I’m too considering Pass amplifiers. What strikes me the most when I read through all these lame responses to OP question, is the lack of almost all responses  to include what speakers they used in their Evaluation of Pass amps. Amplifier speaker interaction is the most critical component matching region when putting together a system. 90% of the responses to this thread are useless IMO.
The weak point is the cover. Tried standing on one and it caved right in. I was holding a Wilson Watt Puppy at the time. So that really was it after all.
