I listen to jazz almost daily through my 4343 studio monitors in bi-amp mode in basement, and 4311B in the living room.
This four-way 4343 were the king of the speaker systems in the 1970s to Japanese jazz fans, they say. If you haven't had chances to listen to 4343 or its upgraded version 4344, especially as you seem to be a jazz fan like me, just go for them. You'd like them very much.
