Full Range Speaker $15-$20000 Range?

I agree with Macdadtexas. Innersound Kaya,
Amazing speakers.

Congrats on your electronics -- great stuff.

The Wilsons and Revels would not work well, as they all drop to 3 Ohms or lower in the bass -- the vast majority of tube amps, even very good ones like the Thors, won't sound right on speakers with these impedences.

As for traditional speakers (non-horns, dynamic drivers), the Verity Sarastro is top speaker that would work, although they exceed your budget unless you can find a pair used. The smaller (and very fine) Verity Parsifel Encore is more on-budget.

The powered speaker idea of Vandersteen 5a's or Genesis works. In the same vein, a pair of Sonus Faber Guarneris with a top subwoofer (Aerial, REL) would sound great, but perhaps leave you wanting on big orchestral and rock.

There is of course the whole universe of horn speakers and horn-loaded hybrids like the Tannoy Westminsters.

The new Von Schweikert VR-7SE would definitely be my first choice, but it would stretch your budget.

I'm surprised nobody mentioned the "fabulous" EPIPHANY 12/12 speaker.15 thou,and worth every cent IMO!Your room seems perfect for these to open up in.I heard these in a room of almost exact dimensions,and with, as well as without the big buck Epiphany sub.IMO they were MUCH better without the sub.They,also seemed to get down quite deeply(don't believe the "bull" about these having a rolled lowend,or "vice like" sweetspot.Best of luck!!

BTW-Way too many people seem to be over the top "bass dominated" in their views.I guess that's why I don't enjoy stopping at red lights,only to hear a mega sub oriented car system BLASTING a tune that doesn't require any output below 80hz!!

I find interesting in that of the five speakers that people have mentioned I have owned 3 of them and of the two others I have owned speakers from the companies. I have had the Andra II's that I sold to upgrade to the Savoy's and also own every speaker in the eggleston works line except now the II's and the Ivy's. I loved the sound of the Andra II's so much that I bought a pair of Savoys. So my home Theatre consists of a pair of Savoys a custom made Andra Center Channel attached to an Andra I bottom and 2 pairs of Rosa's with a Wilson Whow III Sub. I also have a pair of Andra's in my den. The sound of the Andra II's were complete They were excellent sounding and relatively eay to drive. They reproduced piano extremely well as well as resolved female vocals flawlesly. The bass was deep and defined, truly amazing. The upgrade bug grabbed a hold of me and I went for the Savoy's. They are a bit more difficult to drive but I biamp and they truly sound amazing.

The Vandys also sound exceptional in the right room. Because of the integral bass amp they too are relatively easy to drive. The only drawback was that for them to sound their best I had to have them well into the room. about 6 - 7 feet away from the rear wall.

The Wisdoms I already spoke about and wish I could Keep. They also are amazing and provide great dynamic Contrasts.

The Innersound Kaya's I did not own but I did have a pair of the Isis. Extremely quick and resolving but too directional for my tastes. Also the bass could have intergrated a little better. The Current Martin Logan stuff sounds a little more coherent top to bottom but does not have the resolution in the upper octaves like the Innersound.

I have also owned Infinity Beta's (twice), Infinity Gamma's, Odeon 26's & Double 6's, Genesis V's, Mirage M1si's, M3si's & M7si's, Martin Logan SL3's, Apogee Centaur Major's, Maggie 1.6's, Wilson Watt/Puppy V's, and Gershman Avant Garde RX-20's.

Like I said right now I am extremely happy with the Egglestonworks line and Wisdom M75's. If you want to see some pics let me know.

Some pretty good suggestions above (e.g., Andra and the Innersound Kaya). I like the pair of speaker I own (S.A.P. J2001 (twin woofer)), but it is no longer made and is a bit above your specified range.

Some other models to consider that I think sound good and would do a good job with large-scale classical music are:

Gershman GAP 828
DeVore Silverback
