I have a similar space and a wide range of musical interests (renaissance to 20th century classical, chamber to full orchestra and chorus, classical rock to jazz, female vocals. . . ). My 14.5x23' living room is at one end of a huge 23x45x16' space. I wanted to be able to listen while seated in the living room near the speakers, but also fill the larger space with music during other times. I tried various speakers and ultimately settled on Zu; I now own a pair of ZuDef4s driven by a 300bSET. But it was trial and error - both for the speakers and the amplifier.
Speaker recomendation
I just bought a second home and the room where the new system will go is quite large (60’x20’) with a wall of windows. I’m looking for a pair of speakers that will be more for listening in position close to the system but that can still move enough air for when we have lots of people over. Budget is about $10-15K for an amp and speakers. I have a Moon 340i but fear it doesn’t have enough power to move the speakers I’ll get. I was thinking about Golden Ear reference but my wife and I are more classical and jazz listeners and these are better for rock? Suggestions appreciated!
