Can you share your older Pass Labs experiences?

I think, as always, if you are buying new you should listen to 3 brands:

Pass
Ayre
Luxman

Very different sounds to my ears, and among those you should pick whichever suits you best.

I'm using a 250.8 and an XP 10 to power my Maggie 3.7i the sound is amazing, you're never going to run out of power.
I'm sure you could get by with one of their less powerful amplifiers or integrated if you want. I made my purchase when I read the Maggie, Pass combo won the best at show a few years ago. This sounds like a forever system.

to @erik_squires short list i would add hegel... sound quality is at the same level to the others mentioned

my first experience with pass was an aleph 3 back in 1997... honey of an amp, great tone, but not alot of power so at that time did not drive my proac floorstanders with double woofers too well

but at lower volumes it had such a sweet sound, almost tube like in tactility and nuance (but of course without the ’bloom’)

Considering the feedback from others I’ll add some further thoughts. The XA lines are warm and natural with low power. The X lines are very powerful but less warm. Pairing is important, for the XA series with the right speaker and the X series the right preamp. It is a question of taste as to what you are looking for. An X amp can provide the power you need for electrostatics… but if you like a bit warmer presentation, then a warmer preamp than the Pass may be what you want… maybe an Audio Research, Collier Jackson, or VAC.

Have run the X250.5 with modded Revel F208s and stock Audio Physics Virgos.  Used tube preamps - Sachs, Supratek and Airtight.  Great power, presence, tonal colors.  My first impression of this amp has remain unchanged.  That is, "PassLabs sure the hell knows how to do solid state amplification".  I have the Parasound A21+ amp.  Very nice sound after 50 hours of playing but not to the level of the PassLabs X250.5.
