Its a very dificult situation, I used for two years a DM603s3 with a Mac gear, and fell fine about this stuff, but later i get a pair of 683's. My firsr impression about this speakers was excellent, wide response, space and for the price nice bass, but remember that we have to put some hours of use to get more warm sound, just like the others 603, actually i put it on tubes, quite excellent, the other problem to the 683 is the space, you nned a lot of it to play well, if you have a reduced place try the 682.
B&W 683 floor standers
I'd like to hear from those who own and play these on a regular basis. How do you like them overall? Are they too boomy at times? What size is your room? I'm considering them as an upgrade from B&W DM603-S3's. My room is moderate in size (2400 FT3) with 2 openings to hallways, no doors. What do you think? Do they produce good slam and punch at the low end? My room is bass starved and needs powerful speakers in this dept.
