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

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. 

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.
and has won many awards .thereis a distribution center in  Canada
and one in the U.S.
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 !!

Since my brother owns one and I know them well
