LUXMAN 505u?

Rosedanny--Thank you very much for your insight on this amplifier. Now, I just need to go out an audition the Luxman L-505U and hear for myself. I did listen to the Luxman L-507U briefly (It sounded wonderful!!) as the dealer did not have the L-505U but since this amp cost almost twice the price of the L-505U, I am not sure if the sonic character of these amps would be that similar. Thanks again!

How does the Luxman L-505u integrated amp (or the L-507u) sound compared to the Luxman L-550A II integrated? Maybe the real question is how does the Class AB amp compare to the Class A amp? It is my understanding that both Luxman amplifiers are not dual mono design yet have XLR inputs. Is this a concern? My friend recently purchased a Luxman L-550A II Integrated for his Sonus Faber Auditor M speakers and wants me to look at Luxman (I own the Ayre AX-7e Integrated and like it very much). He is very happy with his Luxman Class A amp with these speakers.

I have yet to hear a Class A solid state amp that is fatiguing and tiring to listen to.
This includes the Class A's from Accuphase, Lamms, Pass Labs, and others.
I think the ancilliary wiring and cords would make a difference though.
Perhaps there is some sort of mismatch somewhere along the chain.

For those who owns the 505u, even though its a 100w amp, how is the power ? is it more powerful than what the specs suggest ?
I'm very curious about this amp & hope to audition them soon as well.

I have a 505u and play mostly vinyl. Great phono stage and plenty of power - I rarely have the knob much past 9 o'clock. I use Monitor Audio RS8 speakers. I love this amp. Sounds wonderful. I didn't have the chance to compare it head-to-head with teh 507u, but that's almost 2x the cost, so I was doubtful if it was worth it. Highly recommend the 505u.
