I don't know, I really like B&W's speakers, and was leaning towards those until the floor demo/used deal on the Studio's came up...The only difference I could tell between the B&W's and the Studio's was slightly less airiness and less detail vs slightly less bright or harsh sound from the tweeter at times...it was very subtle, and hard to tell which one was better, but I felt the Studio's were slightly over doing it and almost went with the B&W's.. Then the deal o' the century came along and I pulled the trigger...haven't been disappointed though.
I don't know if these same traits apply to the Monitor and 600 series or not, as I haven't spent enough time with either, but I suspect they're both pretty close too, but I would recommend against the Monitor 3..the Mini Monitor's going to do just about everything as well, especially if you have a subwoofer, and that 8" woofer in the Monitor 3 sounds a little funny to me. Don't get anything bigger than the Monitor 5, the value's just not there IMO.

This is really the age old debate for larger speaker companies...build em' inhouse cheaper, or let the masters build them.
For the entry line models, I think they're further ahead to build their own, but for speakers like the Studio's, 700 series, (speakers handy to $1000 - $2000 ) most $50-$80 drivers from Vifa-Speak, Focal, etc, I've heard completely ouclass what speaker companies seem to offer...and the higher up you go in price, the wider the gap. For peanuts more cost per speaker I honestly feel they'd be further ahead to outsource still. They'd probably slim up the profit margins a hair though...tough call.
But I'd love to see the Revelator tweeter in the Studio's...
Just my rant for the day...
