Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

Ha, just stumbled upon this again while looking for posts on reducing noise.

It's a simple thing to just plug the two-prong jack the other way by flipping it 180 degrees - doesn't matter if it is soldered or not at the Polysix side, of course.

Actually, I did this for my DAC's PSU that I built myself, and one of the two ways provides mch better sound. The orientation probably shows differing levels of leakage currents.

You can do that for any audio equipment with two prongs, provided the two prongs are both small enough in Northern America as one slit is smaller - at least that's how it is in Canada.
