Anyone ever heard of this speaker manufacturer ?
They've been around for a few years. Made some decent impressions at CES and other shows. 
How to hook up two 5.1 channal analogs to receiver
Try the Sony TA-P9000ES. It has 2 6channel inputs and a 6 channel bypass input (also a 2channel bypass input). 
XLR, Balanced, same thing???
Balanced means that there are two signal lines, of opposite electrical phase and equal amplitude. Neither is referenced to ground. The most common balanced audio connector is XLR. (Unbalanced has one signal line referenced to ground.)However, as y... 
SACD setup help

Best amps for new B&W Nautilus 800's
Actually, they were not biamped with the BCs. Instead each BC was bridged to a monoblock for each channel. The eVo2s work well, too.

Theta v.s. Sim Audio
You oughta go listen and on Maggies. They do sound quite different. 
CES 2003 show: do they sell products?
Officially, there are no sales. However, some(!) exhibitors will sell displayed merchandise at the end of the show to avoid costs of return shipment. Catch as catch can. 
Are Capitole and Mephisto recommended components?
I do not recall either being reviewed. You can check this at the Stereophile website by doing a search of the back issues.
