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

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. 

I'm a huge fan of Pass, but I don't think their ideal for everybody. They may be some of the best built amps, but the best sounding amps is a more personal matter. There's a huge difference between his single ended Aleph series and something like the XA25. Same goes for the J2 and F7. 

Fantastic Integrated my brother just bought one a month ago 
Gryphon  Diablo of Denmark  this is a work of Art  it is better sounding then the majority of seperates . I owned a Audiostore
and inside parts quality and engineering design are critical.

this is Built, tested and retested on many parameters before for days before passing and very powerful and doubles in power from 8-2ohms.a Fantastic product  which I rarely will say !!
