When you said large and open it makes me think less boundary reinforcement and might be better of with something like the Volti or Forte 4. I’ve owned Devores, Verity, Daedalus, Zu Union, and demoed the D7. I really like the Forte but I’m in a less than ideal setup with a lack of side walls. They play really well. FWIW never thought I'd be a Klipsch owner.
Spendor D7.2 Pairing - First Watt F8
I have a First Watt F8 with a Modwright LS100 as a preamp. Considering the Spendor D7.2's to replace my Zu DW 6 Supremes. The Spendor's are rated at 8 ohms and 90db efficiency - their specs show amps from 25 -200 can handle them. The F8 puts out 25 Wats per channel into a typical 8 ohm load and loves efficient speakers. Anyone here running this combination or have thoughts on the Spendors paired with a Class A like the F8?
