I've got a great 5.1 system but am looking to turn it into a 7.1 dream system. I'm currently running a 5.1 theatre with B&W speakers all round, including a pair of B&W 802's for my front L/R. I'm powering the system with a 7 channel Lexicon amp, so that the front 2 speakers are bi-wired (2 channels of power going to each of the front speakers.) I listen to my music on this system but only in 2 channel so those front L/R speakers matter a lot to me. I've heard the new Nautilus 800 speakers and am very impressed by them. But in looking at the B&W site I came across their "Prestige" loudspeaker or "Original Nautilus" (the ones that look like snails) that sells for approximately $40,000. Though the price tag is intimidating I am not yet completely turned off. I understand, however, that these speakers require 8 channels of power and that B&W recommends 500 watts/channel for "optimum performance" (although I hear that they run them with only 4 X 350 watts at their factory in North Reading, Mass.) Wow! My questions are: since I am unable to arrange an A/B test between these exotic "Prestige" loudspeakers and the Nautilus 800's, has anyone out there heard both of these speakers and can anyone comment on their differences? Are the prestige speakers as good as it gets or are they basically an engineering experiment? Do they sound as good as they look? If I go with the the 800's my plan was to keep the Lexicon 7 channel amp and use that for the surounding 5 speakers but get two Krell monoblock amps for the 800's. Any comment here? Any info would be helpful.
