I would go with Sopra 2's. They should have enough low end in your room. Mine are in a 14x20x8 listening room and they fill it up nicely. I've never used tubes on my pair, but they should sing with the VAC pre/amp combo. Good luck!
Focal Sopra 2 or Sopra 3?
This isn't going to be happening soon as I need to save more for them. (I will have to find a good used set)I have a VAC Renaissance 70/70 amp that I am getting updated by VAC in January to MK IIIS. I love this amp and i am not looking to change it. I may be interested in working toward a different speaker for it some day and these Focals may work. 91 db sensitivity which should work with my amp's 65 pure class A WPC. My current speakers really match well with it, they are Goldenear Triton 1.r's and to me they sound very good. But someday I may want even better resolution, not sure. What issues may I find mating these to my amp in the future? My Preamp is a VAC CLA1 Mk III, it was just serviced by VAC and completely updated to Mk III with new parts. So my pre/ Amp combo is tubes. I've read in reviews different opinions on how these sound, some say rather bright and forward and others do not, say they are really smooth in the midrange so it's confusing. I may just take my amp to a dealer about 1.5 hours away and make an appointment to audition them. Are these a reasonable option? My room is a dedicated listening room with a great deal of treatments, especially with bass absorbers, diffusion etc. The room is 14 x 18 x 6.5 ceilings. The Tritons have a lot of bass so it seems to handle it well after a lot of experimentation in placements of speakers. They are 7 feet out from the front wall and over 3 feet from side walls and about 7.5 feet apart.
