PMC speakers vs B&W... has anyone compared?


I'm coming to realize the next step up the sonic food chain might be more capable speakers then my CDM 9NT's. The Natilus range (804/802) might be the ticket... I've always used B&W's, but have an itch for something different too. Looking at the numbers of the PMC FB1+, seems to tell me their range is amazing - much broader then the 9nt's. I know specs don't tell the whole story so I thought I'd see if anyone with any first hand comparision of these brands might shed some light. What would be considered a better speaker in PMC's line the the smaller Natilus floorstanders?
Jazz and rock on vinyl is what I listen to mostly.
Thanks

Nautilus have warm and woolly bass and have very clear colourations on female voice. They go loud but sound lumpy and uneven. Ok for classical but awful for rock. Dealers always dem with piano music on all the occasions I have listened with them (and others I know found likewise). There is a good reason for this!
As an owner of N802s, and formerly N803, I find the Nautilus to be precise, not colored. Awful for rock? Not in my experience. It is absurd to claim that dealers always "dem" them with a certain kind of music.
I have heard 3 dems of the N800 and each time they picked piano. A friend went to listen to them on the other side of the UK and got piano as well. They sound great on piano so B&W tell them to emphasise that skill! However on rock they sound slow and messy. if you like classical then fine but for more all round music tastes there are much better choices. I found the MB2 sounds better than the N800 on all types of music. In comparison the N800 sounds extremely coloured, lacking in dynamics and speed. This is revealed quite clearly by comparing female voice live and unamplified versus the same on both speakers using a live recording of the same artist. The MB2 tells it like it is and the B&W colours the performance significantly. Which is why abbey road have just bought pmc to use instead of N801.
I agree with Brizonbiovizier. Most B&W speakers are slow, ponderous, and dry (an owner's way of saying precise I guess). It amazes me they have the following given the number of other choices. To each her own I suppose.
How can a speaker be slow and dry? They are opposites. Slow = big bloated bass with little damping. Dry = fast bass which is lean so sounds light. For amps, Naim gear is dry, Unison gear is slow.
