I was thinking exactly the same! That's a normal sized UK lounge!! β
Oops, USA-centric (and especially Florida-centric where square footage is cheap) to assume that wasn't the living room... The corollary is that here, by comparison B&O equipment is so expensive that anybody who bought B&O would have large & fancy digs to play it in. (All the old B&O catalogs here showed the equipment in beautifully-restored century-old Amsterdam-merchant dike-lofts...)
The other thing I didn't think of, because it rarely happens here in the USA, is swapping out equipment at a dealer. Sean, if you're really going to do that, and considering an Avant as you say, then my concern as to overheating would go away with their dual-axis moving stand. It would still block the radiator when parked against the wall but at least it would spin out and away when turned on, thus not overheating itself.
