I think Audoifeil has a point, I liked the 802diamond but I could not bring myself to buy them. I have a love/hate relationship with them. On one hand I think they are very engaging (bass punch and the vocals grab you) but on the other they always sound unnatural to me. The mids are peaky and the highs while VERY good stand out to me.
As a side note I think Revels (in general) throw vocals much like my Thiels. They spread the vocals very wide across the whole front stage. Where the 802diamonds are much more focused. The focus of the vocals maybe what is drawing you into the B&Ws (or it could be the 4k peak). For a point of reference the Sopha 3 runs a center line between the 802diamond and Revels having good spread and focus at the same time.
I did compare the Sophia 3 and 802diamond in the same room and system... I am sure someones head will explode when I say this but I liked the B&Ws better. They were more detailed in the mids, and highs. The bass of B&Ws also had a more defined initial whack of the bass drum. But I could not get over the oddness of the sound stage of the 802diamonds. The mids were nice but as Audiofeil points out they just sounded unnatural and produced.
This is an odd hobby though, and everyone likes what they like. Just because one speaker is better it does NOT mean you will like it better. With that said there is no doubt that the Revels are the better (better=accurate) speaker and IMO is one of the best buys in audio right now.
Nab2,
How much toe in are you using with the Revels? You may get more focus in the vocal range if you toe them in pretty far, of course the soundstage will get smaller.
