Are Pass Labs amps probably the best ever you can buy ?

Pass is excellent. I prefer Ayre and ARC, maybe Rowland, but it's hard to make a bad choice with these brands.

I’ve owned Pass mono amps and a Pass integrated amp. Excellent amps. Earlier this year I picked up a Bryston 14Bsst2 amp to drive my Magnepan 20.1 speakers. With the Magnepans I prefer the Bryston to Pass. 
I agree with elizabeth’s suggestion to first pick a speaker and then the amp.

Thanks for all your recommendations.  
There seems to be many choices.  I have to listen to them all.

The ONLY concern with Pass I have is the furnace effect.  But I guess class A has its cost......
