Hi again Sarang,
Excellent advice and options from Grunt, kcarlile and others, and yes, you'd still appreciate the superiority of the M80s at quieter listening levels. I have the M80s as well in my apt. but I mentioned the M22s/sub combo because of the placement versatility in an apartment living room.
Grunt's advice on judicious use of the subwoofer is excellent; you'll get some idea of how good the isolation is in your building by simply listening to see if you can hear anything from any other tenants' suites. When I first moved into a rental modern high-rise in Manhattan, it was one of the noisiest buildings I'd ever lived in. I could clearly follow the lyrics of the Dylan songs played my neighbors.
My current place is wonderful--the old 1930s "pre-war" buildings have walls that are very thick. Even so, very deep organ pedal notes from the EP500 travel through the structure and I can just detect them as a weird non-directional reverberation from the foyer of my building.
I still limit the maximum levels I could potentially use with the EP500 and the M80s because I don't want to risk annoying anyone. I think you'll be fine with the sub and the M80s provided you regulate the playback levels based on how soundproof you think your building is.
Regards,
Alan
