I agree - but I can still wish!
What I would really like is the ability with 5.1 input, with either HDMI or Analog (either one would be fine), to direct the two surround channels to my rear speakers instead of my surround speakers.
I can do it with a 7.1 analog input by connecting the surround inputs to the rear input connectors, but I would like to have the room correction provided (cake and eat it to...).
If they would allow, via software, to pick the surround channel output for a 5.1 input on HDMI, then that would also work and be the best solution.
I am considering buying a couple of switchers that would allow me to do that with my interconnects between the pre-amp and the amp, but that will then apply the room correction for the surrounds to the back channels.
The problem is I like my Paradigm ADP speakers for surrounds for movies, but I prefer my rear direct speakers for surround music.
Maybe I need to buy a pair of surrounds that can switch between modes.....another option, but to get the best out of the room correction you would need two separate solutions for the two modes, which is not available to my knowleddge.
Oh well, I may as well stop worrying about it and just enjoy the music!
You are of course entitled to set things up as you please. So, if you prefer an effect over accuracy, that is your decision.
Yes, Audyssey does not support multiple solutions at the moment, so your idea would EQ the back speakers as though they were the side surrounds - a further source of inaccuracy.
