I had a set of B&W N803 for about 5 years, and N805 before those. I auditioned the Double Impact, and found them to be good, with nice soundstage, but not really smooth across various frequency ranges. I felt there was a bit of "suck out" in mid bass. I sent them back. They did have a nice "live" sound, and I think they are good for the price... but not the giant killers others have suggested.
Then I got a set of F208s, and I think they are extremely smooth and flat response across almost all FRs. I'm very happy with them, and have sold my B&Ws. I've had them for about a year. A few audiophile friends have listened to them, and have been very impressed. IMO, they are a step up from the B&Ws, and a solid improvement over the DIs.
I think the Revels are a good choice for you.
