I've had my trusty B&Ws for years, and it is one of the best bookshelf speakers I have listened to. However, I really like the enveloping sound of a nice floor-standing. However, I've never actually owned a full loudspeaker that was worth its salt. I've noticed a pair of these Mirages available in my area, and I thought that I could exchange the B&Ws for these. Would it give in an improvement of the sound? I know the consensus for the B&Ws is an overall flat sound, but I have no idea what the Mirages are like. Would I gain a better sound out of these?
