Looking for a SS integrated Amplifier recommendation going into a new system


While waiting for a new speaker delivery, I have some time to start looking for a SS integrated amplifier, and hoping for some recommendations.

The speaker to pair with is Ascend Acoustics Sierra Tower with RAAL tweeter option that is around 91dB efficient, and the room size is 12x18x8.  I mostly listen to classical, jazz, female vocal, and the listening level normally is around 85dB, occasionally go up to 90dB.

I originally was looking for class-A integrated amplifier, but now would like to open the possibility to class-A/B as well to see what will be a good match for this new system I am putting together.

The Luxman 590AXII is a very nice unit and will be able to meet your needs with the speakers you mentioned under most situations.
What is the size of your listening room?
I own a Luxman 590AXII and like it very much, I have not heard what other Luxman integrated A/B units sound like compared to the 590AXII.
I have the RAAL SR1a headphones and have tried a lot of amps with the RAAL. The very best by far was the KRELL K-300i.

First 90 watts in Class A. Huge bass and so smooth. Look at what Stereophile says about this unit and compared to the Boulder 866 and a few others.
Another vote for the Luxman L-590AXII. After more than 20 years of messing around with more than a dozen of amp combinations both integrated and pre/power, the Luxman beats them all for sheer simplicity in a one-box (minus extra cables) and of course, sound quality. It is high quality at a price that’s not too astronomical. I also own a Naim separates system and another integrated amp but the Luxman is the new reference that gets to stay in the main system.

Good luck.
A lot of great choice and recommendations.
I Second the Simaudio 600i recommendation and you should also look at  Belles Aria Integrated Amplifier from Power Modules. https://powermodules.com/aria-integrated-1

Well, if you’re in the market for a true end-game piece and open to used, here’s a Vitus integrated that retailed for $27k available for $11k that’ll nail all your hot buttons and you’re set even if you upgrade your speakers significantly in the future...
