The 804s tonal balance is a little brighter and tighter sounding than the 805s. Many have commented on the 804s being a little bass shy but I found a good quality, high current capable amp should alleviate that issue. The 804s do respond well to high quality components. In comparison the 805s sound is a little more rounded and even handed with its well balanced coherence. Depending on your room acoustics the 805 with a sub might be more flexible and pleasing with its greater bass impact. Otherwise the 804s is a good choice if you prefer a two box solution.
How different between B&W 804s & B&W 805s????
I'm currently using a pair 805s and having a good chance upgrading to B&W 804s. I know that floorstanding speakers always better than the bookshelf but how different??? I'm also saving some money 4 my new amp(my target is Mcintosh 6900 or 2275), so, shoud i upgrade this speakers or saving that money for my future amp????
