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

probably the best ever you can buy...

'Probably best' to reframe the above.  : )

I'm writing this as I listen to and enjoy my system with my Pass XA30.8 in it.

Having said this, I prefer my T+A PA 3100 HV. 

The T+A stands strong after being tested versus a number of amps, including the Pass XP20 and XA 30.8 pairing. Recently, I used the T+A's Pre-out and I was really, really surprised by the sound quality of my system. I'll be doing the same with the amp section once I get a proper XLR cable in system. 

I encourage you to consider the T+A. Once the savings from a reduced interconnect and power cord count and isolation, are factored in, you will be ahead financially. It's also more feature laden and flexible than my Pass separates.

Let me repeat that I really like my Pass gear.

I happen to like, appreciate and enjoy the T+A to a greater degree, given my system, personal preferences, etc.

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

Many amplifier companies have fanboys. Not just Pass. Each brand may bring a slightly different flavor to the game, but all are great amplifiers.                           
My primary reason for NOT owning a Pass amp is no local dealer.Plus the big class A amps are furnaces you cannot leave on 24/7. 
My best local dealers sell Audio Research and Bryston, BAT and a few others. I chose Bryston myself, as it was the most recommended with my particular choice of speakers.                          
Generally folks suggest choosing the speaker you really want, THEN picking one of the amps which are best to use with that speaker.   
I have read here folks who want a specific amplifier, and then ask what speaker can go with it?

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......
