Another thing Soundhound told me, when he was here, is some psycho-accoustic effects are best played back in regular two channel stereo. The added "direction-enhancing" (for want of a better word) effects won't work as intended he says, after passing through DPL II or DTS NEO:6 decoders. I'll leave it to Soundhound to explain the specifics of why this is.
