SOMMY,

Where did I do that? I was talking about EQ all along, then you mentioned combining, and pitch shifts, etc. But okay, as long as we're back to EQ only we're cool.

What's a PRC? Anyway, there's no "combining" of bands in a regular console EQ, which is something you brought up.
Just so we're all clear, I am talking about phase shift as used in a conventional equalizer. I am talking about the fact that equalizers rely on phase shift for their basic operation. My contention is that phase shift
all by itself is totally harmless and inaudible. It has no sound by itself. Only when you use phase shift to create a second path, which is then combined with the original signal, does the frequency response change. And in that case it is the change in frequency response you hear, not the phase shift. And yes, of course I have auditioned phase shift all by itself. The problem is it's very difficult for most people to audition phase shift alone. Well, I amend that - now that LittleLabs has their IBP it's now possible with an off the shelf device. I had to make my own.

Okay, fair enough.
But I cannot for the life of me imagine how a conventional EQ circuit is going to create a pre-echo of sufficient delay or magnitude to be audible let alone a problem in practice.
I'll also say that even if under highly controlled circumstances it's possible discern "artifacts" related to phase in a typical EQ, it's still
very far from the main problems most folks have to contend with when trying to make good recordings.
