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.

TIA

Since I can recommend only what I have owned or heard, I have three. If money was no object, I would buy a used Vinnie Rossi L2i. The new Vinnie is coming out soon and is significantly more expensive. The Vinnie made every speaker connected to it play beautifully, and I heard about a half dozen different pairs: different KEFs, Dynaudios, Dali’s, and QLNs. If I had a difficult room, I would consider a Lyngdorf. The DSP is great. I own a Simaudio 600i, purchased used, and have enjoyed it. It seems to check all my boxes. I am very tube curious, and I auditioned an Octave V 80 SE. Wow. Very nice, but it was just out of my price range. The bass was really something. And the tubes are so cool! Good luck. Keep us tuned in. 
Thank you all for the inputs.  They are great thus far and help me to check into some wasn't on my original search path.

I will have a chance to do home audition for Luxman 590AXii early next month and if I could arrange the schedule well, I plan to get a Belles Aria Signature here to do a test drive as well.

Not having first hand experience with Belles Aria Signature, I wonder if anyone can provide some experience on this unit?

If everything works out as planned, I will see if I can get a PASS Int 25 for a test drive as well.  Meanwhile, there are couple stores I contacted will have audition schedule available next month.  It is going to be a busy December.
Since you mentioned tone is important to you. I would also add Accuphase E-650 to the mix. I started a similar thread a few months back and ended up with it, and am very happy. Good luck and have a fun December with auditioning and deciding.
The biggest problem I've run into is that few equipment makers have enough inputs and outputs.  They also do not work automatically or intuitively.  Adjustments need to be made on the amp or player to make them run and when you change discs, the process starts over again.  On top of that while SACDs sound better, I do not find 4 or 5 channel listening enchanting. After going through this for several years, I decided to stick with stereo, even listening to multi channel media. Like you, I have found a value in buying these obscure editions.  Like you, I have found my quad records, my SACDs and my DVD audios to have climbed in value.  Besides many of them are mixed a bit differently, so they are collectable Best of luck to you.  Steven
