High end bookshelf speakers for Small room

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.

I have a Luxman L-509X integrated amp, and it drives my KEF Reference 1 Meta speakers brilliantly in my 13’ x 13’ room. I have an equilateral 10’ triangle of speaker distance from each other and the MLP. The imaging is completely separated from the speakers and almost entirely behind the speakers. It’s just uncanny.

I forgot to mention that although the speakers hit a solid 30hz in my room, I do use a JL Audio E112 subwoofer to augment the output below that.
