My serious recommendation would be the Spatial Audo X2 open baffle speakers for $9600. I have their smaller M4 Triode Master speaker and love them. The X2's are super efficient and go pretty much flat down to 20Hz.
Still looking for speakers in the 10-20,000 range
I’ve heard Proacs, Personas 3 and 5, Ryans, Wilsons, Wilson Benesch, Monitor Audios, B and Ws and several others in the 10-$20,000 range. My favorite so far is the KEF Reference 3. I would consider the Reference 5 but, as I’ve posted before, there is no place to hear them within 400 miles. Still plan to hear the Focal 2 and 3. Unless I love the Focals, I'm inclined to either go with the KEF Reference 3 or wait a couple of months (or more) to check out the new Magico A3. My room is 24x18. I have Audio Research electronics and 20 plus year old Proac Response 3.5 speakers. It’s been a long process and I’m not sure if I’ll be relieved or disappointed when it ends. Hard to decide if the Magico’s are worth waiting for. Thoughts?
