No matter how many times you say it, no matter how
firmly you believe it, it does nothing of the sort.

You assertion is that two systems with the same square
wave response will sound the same, or certainly alike,
and that's provably hooey. Consider the following as a
practical counterexample: Take a perfectly flat, linear-
phase system. It will have, for its bandwidth, "perfect"
square wave response. Listen to it, it will sound fine.
Now, take the input, delay it 10 mS, and sum it with
the output of the system.

Put a 1 kHz square wave in to the system: it will
have an identical square wave response.

Now, listen to it, it will sound absolutely dreadful.

You keep going back to the ringing canard as if it
had any signifance in and of itself. A PERFECT
band-limited system MUST have a substantial
amount of ringing, Gibbs says so. You say different,
in contradiction to well-known facts.
