You may want to wait a few weeks. B&W coming out with a new line.
Yes, I am a true believer that the 800s are 'that much better' than the 802/801s. Now, that being said, are they worth $5K more? That is completely subjective where much depends on the depth of one's pocketbook, not to mention amps, power coming from the wall, room, ears, and knowledge to hear the difference. I don't claim any of the above to be perfect at my house, but I feel they are worth the extra $5K!
why don't you further modify the matrix 801?
the crossover and the cabinet can be improved for
less money than the nautilus line. i like the nautilus
speakers-- more resolving, more accurate. but i am
very biased towards the m-801- a rigid stand, a properly
executed crossover, and you can pretty much forget about
what else is out there (unless you have $15-20k lying
around). ps-- anyone have a pair of m-802's in white and
black (mint) that they would like to tease me with?!
