Class A or AB amp for JBL S4700 speakers

Luxman also lacks depth. Audiolabyrinth is right about the XA series. With a high sensitivity I also would go for the XA series.

Ok, well .8 or .5? And which model? 100, 160? Also, I don't like Pass Labs preamps. Not enough features on there for me like bass, treble, sub. filter, mono switch, etc. Is there are preamp out there that has this stuff that would go good with the Pass Labs amps?

the 100.8 or 100.5 is enough for your speakers. I would go for a tube pre-amp in your situation.

I agree with Bo1972, A tube pre-amp is what I have always preferred myself with solid state, Dave, The only pre-amp in the world I know of that has treble and bass controls is Dan D Agostino's momentum solid state pre-amp, that my friend is beyound our bucket list, although the Dan D Agostino equipment is way beyound the pass-labs and krell with performance, A whole different league! It also comes with, what I call stupid money for pricing!, If I had the money, The Dan D Agostino master systems amplifiers is what I would have period, cheers.

Ok, which tube preamp that has all of the features do you recommend. I know McIntosh solid state *and* tube do. Accuphase and Luxman solid state do too.
