I watched a TV program a couple days ago (I must be getting old - I can't remember which one it was) which displayed a "Circle Surround 5.1" message on the screen at the beginning of the program. I am aware of Circle Surround - Theta once offered this surround mode on its Casablanca processor (maybe it still does), and Circle Surround itself once offered a standalone decoder. Widescreen Review gave Circle Surround a very positive review several years ago. I was not aware, however, that this system had gotten anywhere beyond that. It is rarely mentioned here, on the AVS Forum, or anywhere that I visit. Are there any other processors that include a Circle Surround surround mode? Is it worth pursuing?
