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

I have about 15k to spend on an amp/preamp/integrated amp.

I mostly listen to smooth jazz like Dave Koz, Rippingtons, Brian Culbertson etc.... and loud.

I have yet to hear any amp that comes close to Pass Labs.

Your experiences pls ?
But I wanna keep my Had amp...I like it...and have decided to send the 4 grand to Almarg as that seems fair. However, there was a temporary weird crackling sound from my speakers which I now realize was Kosst
"underscore" Amojan crunching their numbers. 
Yes, that sounds very fair indeed, Wolfie. And it will cover most of the cost of my XA25.

I’ll let you know when the check arrives.

Best regards

That is such a hard question to answer, I had a Pass X350 and it was quite sterile sounding, beautiful build quality but not for my system
at the time. Your question is impossible to answer as it depends on your personal taste and your system. There is no such thing as a best component, it’s too subjective. You should be asking yourself what do you like the best as that’s all that matters!!!
yes, I love my pass 250 and X-ONO. Had others eg Parasound. 
Pass is a different league.
Not sure if anyone mentioned this (probably), but not every amp is a great fit for the speakers you have.  So 'best' really can not apply to any single piece of gear.

We sell Wilson, Sonus Faber, KEF, and others and have been Bryston dealer for years, but grew up on Classe' and Mark Levinson.  When we took an older PASS 250.5 in on trade and it simply bested our brand new (but burned in) Bryston 14B3 on a pair of Sonus Faber Il Cremonese's, we became a PASS dealer.  We've been pairing PASS with most Wilson's and have not found a bad combination of speakers to run with them.  We also demo all speakers over $10K with a pass amp and often sell the amp too.

I typically avoid the forums as a dealer so as to not promote ourselves,  but we really do like the PASS products (despite the fact our current order of gear will ship Feb 2019 :-(
