I use it and am quite happy with it. I just don\'t use it while tracking. I throw it on the main stereo bus during final mix. It does wonders on top of SoundStage (Cakewalk FX3), which I use to give each instrument a unique place in the stereo stage.
I\'d point you to two demos I uploaded on MP3.com, but they\'re having database issues and the pieces haven\'t been approved a week and a half later. Could this be the death throes of MP3.com?
I guess my point is SIR is something that only makes sense as a final mix item. Isn\'t latency mostly a tracking issue?
