Is it fair to assume that since you’re posting on this site that you’re shopping used? That opens up most all the speakers on the market in the world most of us live.
Dynaudio Confidence 50 would be added to my list and even the C60 that had too much bass for most rooms could be a great match for your room.
Usher BE20DMD
Paradigm Persona 9h
Meridian dsp8000se
KEF Blade (my current speakers)
Legacy Aeris
Klipsch Lascalas
Focal Sopra 3
I used a similar price point when shopping for my upgrade speakers and I tries a few on the list above, some had too much bass for my room 3400 cu/ft while some just didn’t sound right with my source. The Salon 2’s sounded really lean because my integrated didn’t drive them full range.
The gent I bought a pair of Salon 1’s from had a huge open room with walls of windows and not enough window treatments and last I heard he still struggles with good sound in his room 10 years later. I could have started a business just buying and reselling his used speakers from him if I was a salesman.
Eventually you’ll have to put your faith in 1 of the speakers and build a complimentary system around them because the odds of getting lucky and dropping something in that sounds great from scratch are slim.
Have fun with it and try to get a demo of the DALI Epikore 11, might be special if you can find a second hand pair.
