Definitely your buildings construction will dictate. Im in a co-op built in 1960 and the sound isolation is terrible (as is every other NYC post war building Ive been in).

Anyway, Ive tried all kinds of systems and I ended up with a simple system based around a pair of Harbeths. Theyre designed to be the best low-level listening speakers for all day listening. Depending on your room size, a pair of Harbeths with an integrated with some juice - something like an NAD 375 and youll have a versatile, great sounding system with your current sources...
