Ah, yes, why didn't I think of it earlier, the Signature Diamond...they are supposed to be getting a pair at my local dealer as soon as they are finished with the dedicated "Nautilus" room...but I do stand by my earlier quote:
I would be worried that they would be too fatiguing to listen to...
I have spent a good deal of time in the Nautilus 800D room at my local dealer and have decided that after about 15 minutes the forward presence of the diamond tweeter just becomes a little too much for my ears to handle...I also recently acquired a pair of 804S's (granted not the diamond tweeter) to try out and after about 5 minutes I decided that my JM Labs were much more musical and clear...the instruments actually sounded like what they were and not colored (as in the case of the horn in one of my favorite recordings) or hidden (as the inner detail of the winds) by the b&w's approach...Give me a pair of Aerial Acoustics, or some Focal's or some Wilsons or or or....I love the look of b&w but for critical listening (especially to symphonies and other orchestrated music) I can put a lot of speakers ahead of them at fractions of the price points.
