Food for though - inflated dimensionality is not always better - it just means the system has phase issues.
Amused to Death deliberately takes advantage of some very distinctive technology called
Qsound to create spatial effects via processing. There are not that many projects recorded using this effect and it is more of a novelty in my opinion. Here's a quote from that wiki:
It is important to distinguish 3D positional processing (example: QSound i.e. the multi-channel QSystem professional processor used in the production of pop music and film audio) from stereo expansion (examples: QSound QXpander, SRS(R)Sound Retrieval System). Positional 3D audio processing is a producer-side technology. It is applied to individual instruments or sound effects, and is therefore only usable at the mixing phase of music and soundtrack production, or under realtime control of game audio mixing software. Stereo expansion (processing of recorded channels and background ambience) is primarily a consumer-side process that can be arbitrarily applied to stereo content in the end-user environment using analog integrated circuits or digital signal processing (DSP) routines.
That said, holographic presentation is very important to me in listening to my system, and is the primary reason I think I prefer SET amps. As far as live music, I think it depends entirely upon the space/venue and the way the music is amplified (if it is). In general, it certainly does exist in that we can hear spatial cues, but many performances I hear live do not occur to me as spatially compelling, for lack of a better descriptor.
Furthermore, I think it's pretty absurd to compare, or rather to base one expectations of a home system upon what live music sounds like. They are two entirely different things and can be enjoyed on different levels and to different degrees. Fundamentally they both present music and connect with us emotionally on that level, but trying to reproduce "live" at home is the proverbial carrot on the stick - it's never going to happen and is a sure way to stay on the merry-go-round of continuing to strive for the impossible (when there is SOOO much to enjoy in what actually IS possible and holographic presentation is part of that).
I do enjoy, Amused to Death, by the way, I just consider it's spatial presentation to be a novelty and I don't think I'd want to hear all my music presented that way.
