I have an opportunity to buy DM7's or Matrix 3's.
My listening room is 22' X 20' and the speakers would go along the 22' wall.
I listen mostly to orchestral music.
However, I don't crank up the volume to painful levels.

I have also considered purchasing 683 or 684 but I believe that the older B&W models mentioned above
would handle the full orchestra better due to their sheer size and that they were closer to the best B&W
models whereas the 600 series are entry level.

I have listened to B&W 804's a number of times and am always impressed with the sound quality but I myself have never owned B&W speakers.

All help/comments are welcome and appreciated.
