Yeah, Luxman class A within your budget is $5.5k, 40 watt/ch/4ohm. If it is a very conservative figure - it might be enough for moderate level listening, I don’t know. Could be interesting to compare it to Luxman A/B, $4.5k. My wild guess - depends on what you are listening and how loud, there might be no clear winner.
inna, take a look at the link I posted earlier. The Luxman L-590AXII actually is putting out over 150 wpc into 4 ohms. Used, a very nice L-590AX probably will be about $4000. (this is the version before the MkII came out) The newest version, the L-590AXII, used, maybe $6500. I’m not sure why Luxman insists on only claiming the Class A output, and nothing beyond that, I think they’re doing themselves a disservice. Once again, these are not low-powered amps.
