Integrated Amplifier with the Good Bass and Extended Highs

I have an idea where you can put volume knob.

Just wondering how long you listened to the 505 ux?  I have read a rave review of it in one of the audio rags. I recently purchased a l-507 ux and thought it was terrible when I first hooked it up. I could not believe how bad this thing sounded. (I'm using it with VMPS  RM30 Series II speakers) I let it burn in for several days and it started to sound much better. I have had it now for about 7 days and I am beginning to love this thing.  Turned it off last night and expected I would have to wait to let it warm up again but within an hour it sounded better than ever.  It just sounds better every day.  If the class A sound is what got you then the 590 is likely to be the ticket in the Luxman line but just sayin  you really have to let these things settle and burn in to know what they sound like. 

I wish I knew more, or had more experience to comment further. When I bought my L-590AX I read all the Luxman reviews I could find, which certainly weren’t a tremendous amount. Most reviewers liked the sound of the two class A amps over the others, and the 590 over the 550. I have zero regrets. Bass is super, and very well controlled, midrange and highs are awesome, great detail, but not bright or forward. Also, from one review that I can no longer find, these amps are really only class A up to the rated 30 watts, and then switched to A/B, and were putting out about 90 watts/channel into 8 ohms.
There is an L-550AII currently for sale here for $2000. This would be a 20W amp, which was later superceded by the L-550AX, then the L-550AXII. It looks nice. For me, I didn’t want to wonder "what if", so I went to the 590.
Good luck,
L.

Naim Supernait 2 is a great integrated amp.

For now I am very interested in Accuphase E-270. I understand that the E-270 won't sound like a E-470 but it should have similar sonic signature.
Power shouldn't be a problem, 90W/8Ohms - 120W/4Ohms since I don't listen music that loud.
