As others have said, let your ears guide you. I know it's hard because you're listening to SF and BW in different systems. I own 803 D3s but am not intimately familiar with SF so I won't try to compare them. I used to run my 803s on a McIntosh but now on a Pass Labs power amp. I love the 803s. I've not heard the 802s (someone said they have a better mid range). The 803s are not too bright for me as a rule. I find that production values vary so widely from one recording to another that it's sometimes hard to generalize about a speaker when the production values are so different. I can say the 803s have plenty of bass and exceptional detail. Depending on the amp, the speakers can disappear in the room, fill it entirely, and create a very rich sound that is almost liquidy. I'm sure SF owners will trumpet their speakers as they should. This is a +1 for B&W. It's common to see used 803 D3's go for around $10,800.
