floor-stander speaker for "classical"

I heard the Rega RS3 being powered by the Elicit with the Apollo as the source. The results were very disappointing... 2 dimensional/no bass/small scale/poor resolution/detail and lack of engagement. I asked the dealer if the speakers were "broke in" he told me they have been on the showroom floor for over a year! I'm sure better results can be had in a smaller room, but IMO Magnepan/Martin Logan and Vienna Acoustics offer more speaker at similar costs.

Rega speakers are designed to be used close to a wall and have plenty of the linear bass required for realistic reproduction of the symphonic foundation.

They are voiced on acoustic music and lack the hard-edge and mid-bass bump to match the way rock " music" is recorded. Guarantee you will sound better than Maggies in a room that size. Been there, tried that.

Flashy they are not, realistic they are.

Yeah, that room size is a challenge even for the Maggie MMGs. Someone
suggested the Silverline Prelude. For classical, especially orchestral, how 'bout
upgrading to the Prelude Plus. It's the same physical size with twice the number
of mid/woofers, which should lower inertial artifacts (overshoot & ringing) and
increase dynamic range a particularly good thing for clarity and dynamics in
classical music.

Plus you get the outriggers and real wood veneer, all within your budget.

My room is the same size and I use B&Ws which are well regarded for classical music. I would try the 600 series and CMs.

For classical music, I like BBC school designs such as Spendor, Harbeth, Stirling etc. or of of the more modern variants such as PMC and Proac.

I also use Proac Tablettes which have a natural mid but are not as resolving as the B&Ws.

I'm a little surprised nobody mentioned the Ohm Microwalsh Tall (or that I didn't think of it sooner). I ran the OP's room dimensions through their speaker-matching calculator and of the four suggestions, the Microwalsh Talls seem to be the best fit--6"x6" footprint, 36" high, omnidirectional pattern. 8'x11'x8' (assumed ceiling height) comes to 704 cu. ft. These Ohms are rated for 600-1000 cu. ft.
