Depends on if you like the sound of the B&W. I found the sound of the Dynaudio to be quite a bit different. For classical music, I generally prefer the B&W, but I haven't owned or spent a lot of time listening to the 703.
Dynaudio or B&W
I have a pair of B&W 703s and am thinking about going to a pair of Dynaudios. I purchased a pair of Focus 140s for my other system and just love them. I have been tossing around the idea of the 220s or the X36s. I may go Contour as well but the hang-up is cash. It could happen though. I am using a Jolida JD-1000RC which is plenty for the 703s and I would suspect plenty for the Dyns as well. I listen to everything from classical to metal. Any opinions welcome.
Thanks.
