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

I recently bought a Gryphon Antileon Signature to replace my Pass Labs X350.5. I will receive it next week. I have owned many Pass labs power amps and mono amps in 10 years of time.

This doesn't mean I will never buy a Pass again. Maybe I will buy later XS-300's. I loved all the different Pass amps I owned. And they made me really enjoy my music.

But sometimes you want to look a little further......

To OP. I have an xp12 pre feeding my xa30.8 into my tannoys. IMO tannoys and pass labs are a perfect match because Nelson Pass voices his amps using tannoys. This is the one time that I do not want more from my set up. The realism and ease to the music is second to none to my ears. The downsides (if any) are the xa30.8 takes awhile to sound its best. 

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.

NO NOT bad rap PASS NO weak points.HELLO!
