B&W Nautilus 802 vs. ProAc Responce 2.5

Thanks for your advice, it is great to hear your highly professionals advice. I think I will try to upgrade to Responce 2.5 so, but how would they sound with ML?
My problems could be, that my Cary's are only 40 watts and now I have some problems with driving the Studio 250 is the 2.5 easier to drive?
I have heard some SS amps and I like this fast acurate sound, which are the reason I plan to change!!!

I forgot to say, that my listening room are 4,5 * 4 meters and my equipment are all highend tubes pre/amps with the highest levels of cables from Vantage (the best in my opinion). My cd player are ML 36s/37.

Typically the B&Ws work better with High Current amps and mostly SS. I own the matrix 803s and although they are efficient 91 db, they require a lot of juice to make them sing. Hope this helps. Overall I would prefer the N802s to the Pro AC but there is a price to pay and I think in that price range, there would be moer speakers to consider along with the N802s.

I would definitly chose the Proac Response 2.5 over the 802's. Even though the 802's actually are cheaper where I live. The only reason I would choose the 802's was if I had to play louder than the 2.5 can handle. The 2.5's has more soul and musicality than the 802's and isn't the music what it's all about???

What about the ProAc future series?
The future .5 are warm and very detailed, with an ultra fast and soft tweeter.
