Hello. Man! you people know an awful lot, so this is the place for me to get help. I am looking at building a system. My room is pretty straightforward 27 X 14.5 x 8 I am looking at either the Denon 3805 or Onkyo 801 or 901 or something along those lines up to a $1000. ( I am wondering if I need to spend that much though. Anyway, I noticed the Denon has Dolby IIx the Onkyos only II. As I understand it Dolby IIX will make cd's play through all 7.1 speakers (I have none yet but that advice will be solicited later)and IIx through only 5.1. Does the Onkyo or for that matter any receiver without IIX have a way to send music sound through all 7.1? Am I misunderstanding how this works? Or is that what the dts or Neo functions do in music mode, allow a stereo signal to pass through all 7 speakers eliminating need for Dolby IIX? Thanks for all your help
