High end bookshelf speakers for Small room

Having to deal with a small room after a move I pretty much have the same size as yours. I’ve had really good luck with the Reference 3a Reflector. It’s not a small speaker for a book shelf but I still run it with a pair of rel subs. I do turn the subs off sometimes for the hell of it. Sounds good with or without. 
 

I’m using a 50 watt class A amp switching between kt120’s and 150’s. If you’re looking for an extra warm slow fuzzy slippers speaker this isn’t it. There is something special about a speaker with no crossover. The 3a is not bright it’s very natural with a big wide deep layered soundstage that goes beyond the outside boundaries of the speaker. It can make bad thin recordings sound better than they should. The best part it plays all types of music very well.
 

I rotate other speakers in but always crave that ref 3a sound, I tend to use these more than the other bookshelf’s. 

I'll also recommend the Reference 3A Reflectors based on your room size and listening preferences.  I downsized my listening room (13 x15), and my Legacy Focus speakers were just too overwhelming.  The stand-mount Reflectors worked perfectly.  I then went with a pair of Coincident Frankenstein 300B monobloc amplifiers, a Backert Labs Rhumba Extreme preamp, and finished it off with the Grimm MU2 (DAC, streamer, ROON server) on a single upright stand.  No more big, honkin' gear with cables running everywhere.  Oh yeah, I added about $5k of acoustic treatment on the walls, ceiling and corners which made a huge improvement on the sound.  As @paulcreed stated, the Reflectors are "not bright it's very natural with a big wide deep layered soundstage that goes beyond the outside boundaries of the speaker."  They are rather heavy, especially with Sound Anchor stands, about 150lbs total, but manageable.

I use Elac Vela BS403 with a NAD2200 in a 25x20 room.  Sounds great

I will say the one speaker I wish I didn't sell was the Silverline Minuet Supreme Plus. Those are something special.

I’m becoming very interested in the Platimons VC One speakers.  Some rave reviews.
