Modern ones certainly aren't. They are designed and built by accountants, and as such aren't much use to anyone.
Old ones aren't either because people didn't have HiFi in those days. However a lot of the really old designs seem to be a bit more HiFi-friendly (with the exception of tiny cottages which are so small you end up sitting on one of the speakers).
You'd think the best designs would date from 1960 to late 1980s because that was the period in which most people would have wanted HiFi or a stereo system of some kind. However I'm not sure architects took much notice (they usually don't, I think they have to have 2/3 of their brain cells removed before they are allowed to become professional architects).
