IMHO the 452 will make a HUGE dif in the dynamics and bass even if the volume isn't loud.... its shouldn't be hard to find a dealer that has 452 and 803's on display both pretty common together at least around the NYC and tristate where I am. If you are in the NY/NJ area let me know and can prob help
B&W 803 D3 speakers - which amp?
I just upgraded my speakers to B&W 803’s and currently have a Mcintosh MC207 powering them for 2 channel music and 5 channel home theater...sound is quite good from the MC207. The question is...how much difference will it make if I switch to a 2 channel amp like the MC462?
