You can get a far better speaker than the Sophia or B&W and still get an easy to drive speaker.
Find a Usher dealer it may take a drive to do so, but the BE 10 which sells for $14,400.00 is in an entirely different league of construction and sound quality.
The Usher employs a pure beryillium midrange and tweeter and are in fact the only company in the world to make a pure beryillium midrange driver in an affordable speaker!
The woofer is an Eton 11 same woofer used in Avalon, Kharma, Marten and many others.
Cabinet is 2inch thich birch over mdf with internal dampling materials and lead.
This is a $30k-$40k product. I do not ship out of territory so please contact Usheraudiousa.com and see if you can find a pair.
The Sophia is a very fine speaker and I would take it over the B&W but the Usher is built and sounds like a much more expensive speaker.
We are at HE 2007 on room down from Wilson who was showing the WP 8 and many people commented that we were getting as good a sound in our room.
The only issue with Usher is not enough dealers yet and the advertising doesn't really address how good they really are.
