I'm curious what the proper terminology is for the 3rd dimensional quality that I can hear with some recordings in 2 channel. This is beyond left, right, and vocal placement - it's like depth. Additionally, I'm curious if some discs are indeed better at producing this than others. My reason for asking is that I recently moved my system into a much bigger room which has been great for sub placement issues, but it means that my front mains are no longer equal distance from the side walls and I've had trouble hearing this depth, until last night when I suppose I was in the proper mood to really listen and it was actually a Patsy Cline cd that produced it first. I've been trying to hear it with the new Michelle Branch disk Hotel Paper and I just can't "see" it like that as much as I would like to. I thought it was because of the setup, but I guess maybe it's not.
