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.

I have several kits, including the new Technics Su-R1000 easily driving Floor standing B&Ws with ease and it is an amazing 10K digital amp. However, as the OP has indicated a preference for Class A/B amps, my experience with those is also profound. I know many responses refer the Luxman 590. It is an excellent amp. Personally, I have McIntosh separates in my main system and a MA-:5300 running LS 50s in a small offi e set up. 
All produce excellent yet different signature sounds. My current favorite though is the new MICHI Line. I heard both the MX 3 and the MX5 and they are on your price point, heavy well made and amazingly dynamic. They range from. $6 to about $10k and are quite a package. 
Whatever you choose as always is subjective to your personal spund tastes and peripheral equipment being amplified. Good luck in your purchase. 
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.
