I was wondering if anyone out there has upgraded the Theta Casablanca to the Theta Casablanca II and if so was there any signifigant improvement. Also, anyone tryed the circle surround mode on this unit and is it any good?
Check out the AVS forum, there are a few folks over there that own this piece.
The circle surround card is a big improvement over standard dolby 5.1. I've had this card now for more than 6 months and almost always use this setting.

I have been waiting for more than one year to get Theta to "allow me" to upgrade my Casablanca. Not sure what is wrong with them (or with the mods) but they don't seem at all interested promoting the modification program.
