Class A or AB amp for JBL S4700 speakers

Dave_72, The Tube Research labatories pre-amp is one of the very BEST tube pre-amps for sound quality today!, made in the U.S.A.!, hand built, I said big bang for the dollar going against $20,000.00 pre-amps, ask anyone about one of these pre-amps, nothing but great feed back.

OK, I'll ask you since you're offering advice, what $20,000 pre have you compared the Dude too?

Interesting.. there seem to be gifted ones here who can literally hear sound from what they read. A 'talent' to behold indeed. ;)

*Yes, if heard/compared - providing some detail of the event/s would help the OP rather than making out some coy blanket statements.

Yeah, I noticed that too. I can only go by my findings and listening tests. And the top contenders to me are; Accuphase, Pass Labs, Luxman, and McIntosh.

Until I hear something better than those 4 brands, I'm sticking to those.
