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

The Boulder 866 gets stellar reviews.  Very neutral leaning slightly to the warm side. I have one on order to pair with Rockport Avior ii on order as well. A little above your price range new  so perhaps used. Good luck in your search! 
Hi
hard to select these days 
I just changed from 50 yrs of separates to
peachTree nova 150 and am v v v pleased.
no excessive heat since it’s class D!
not my first class D system!
the customer service is excellent as well!
the unit has great sound not bright and can listen for hours! Great sound stage
clean bass too
good luck
All this gear is great but room acoustics will make or break any system. I have owned 
Boulder
Belles
Dynaco
Mcintosh
Peachtree
Arcam

and I would suggest consider service too
my latest experience I was with Peachtree and service is excellent 
Any of the above combos will wott r k v well in a good room

currently I am using a Peachtree nova 150
and it’s excellent 

have fun





Have you ever auditioned Gryphon integrated amps…? I owned both the Diablo 120 and then upgraded to the Diablo 300. 
Talk about detail - iron fist control - speed - massive headroom - power - soundstage - gorgeous highs and chest thumping lows. I was driving a pair of Sonus Faber Serafino’s and at 90db sensitivity there was oodles of power. (600 watts per channel into 4ohms)
I did compare it to a McIntosh MA352 hybrid and my ears instantly preferred the Gryphon. They pop up used every once in a while, but I got my Diablo 300 brand new for $11,500 from “A Higher Note” in LA. 

Google reviews on both amps. 
Only draw back for me was I didn’t love they way they look. Darth Vader would have been proud to call the Diablo “My Son”…. but function over form…right..?

I should tell you that I have since sold the Diablo 300 for an ARC 160s and REF 6SE - Not a fair fight really, but maybe you should consider a tube piece of gear. Like me, sounds like your ear is leaning that way.

Anyway - I swear the Diablo blew away the 2-3 McIntosh amps I compared it to…and the only pieces I preferred were in the $30k price range.

good luck…!
