So the real skinny is that there does not appear to be any systems that actually use all 9 or 11 channels at the same time. You always have to choose whether to give up two of your surround channels to support either wide or high. I was wondering primarily because I have not seen any 9 or 11 channel amps out there. It would also appear that the codecs do not support the wide and high channels except as an algorithym in Audyssey or Trinnov space. So at least for now we are still limited to 7 channels at a time.

I have toyed with the idea of splitting the signal from my AVP output to two different amps to add extra surround channels. The signals would be the same but would extend the surround effect over a larger area. It might confuse the setup mike a little though.

Anyone know of some actual material out there that actually is encoded to use the extra channels of wide and high or is it just created out of thin air (literally). I think some of the games may use it more than movies. My music room up north has the ceilings tilted at a 45 degree angle and could be very adaptable for some in wall speakers for all of the extra channels.
