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

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......

I used to own a ’tilted to class A’ small amplifier, Forte’4a. With it on 24/7 my electric bill was $7 higher in Winter, and $10 higher in Summer, just due to that amplifier. The amp I have now runs 230watts idle. like TWO 100 watt electric light bulbs on 24/7/365. The newer Bryston amps ’cubed’ models are half that. And yes they do lower the class A level, but still sound better than the squared model. Saving 100 watts left on 365 day a year is worth considering in cost.
To have an amplifier you have to turn off.. Would bother me. I DO now have a preamp I cannot leave on 24.7 as it runs way too hot. (A Conrad Johnson ACT2) In the Summer the heat is really a problem with the Conrad Johnson, and this is just a preamp, not even the monster heat furnace of a Class A amplifier. I know some folks can’t use the main amp in Summer due to the heat from it. So heat generated IS a real factor in choosing an amplifier.

Don't listen to Audio dealers that have something to sell get a Pass preamp and amp even used is fine as Pass is a WONDERFUL company.Enjoy!!

One thing to consider is that there seems to be much more enthusiasm for Pass amps then preamps.  I have a an old aleph ono phono preamp.  It's very clean but way too lean for my liking.
