My room is roughly 18x20 with 8' ceilings. There's a fireplace mantle behind the listening spot -there are two rectangular openings in the ceiling on either side of the fireplace to promote warm air circulation from the fireplace to the upstairs
The area has an open floor plan with two large openings. One, about 7' wide on the back wall to the right of my listening spot, the other on the left which opens to a hallway, so there really isn't much of a side wall on the left.
Hence the room is not a symmetrical rectangle. Actually, if I consider the opening on the right which goes to the dining room, it's more like an "L".
Current speakers are Chapman T7's. Electronics are tube pre and mono amps. I've had the Chapmans for years and they were upgraded recently. I could not afford them now if I had to purchase new. They're about 11 or 12K I think.
Speaker budget is under 5K. I neglected to mention that. I saw pics of the Raidho and Sonus Faber online- gorgeous but beyond my relatively meager budget. I'll talk to an audiophile buddy of mine about Dynaudio- he has a pair but they cost far more than 5K. His electronics are also stratospherically-priced relative to my wallet.
I'll check out Totem online and hope there's a local dealer. This should be fun. I know a lot of folks love Pro-Ac and other monitors closer to my budget and I'll explore those.
Thanks for all the responses!
