D220 pro CI vs D440 pro CI

Thanks to all of you who have commented on this. I didn't realize that a small room could be such a factor. I have thought about going through the headphone route, but I just could't imagine a headphone being able to carry the big sound speakers can.

My room is a dedicated listening room so I can do something with it. What specific things could I do to the room?

thanks, Jay
