Hi Ethan

I can't remember the exact frequency, I made an audio file from a sawtooth wave from a middle-of-the-keyboard note in a soft synth. Then I cut a one second bit out of it, made a copy and flipped the phase of the copy, and made a repeating two second loop of the two samples.

I was listening on my lipinski 707's, which should be very accurate speakers. There was an obvious (but hard to describe) difference, from memory it was in the mids and sounded possibly like different harmonic content. It wasn't huge, but it was definitely not an "I-think-there-might-be-a-differnce" type difference.

I would redo the test and post the sample here, but I sent my converters in to get repaired today, perhaps someone else could do it?
