Anyone HEARD the qol 'signal completion' device?

My question is directed to those who claim to have some idea what the QOL is doing: Is it something that could be done during the recording and mastering process? If so, then it would seem to qualify as a distortion device; i.e., something that changes what was originally intended.

I haven't heard the unit, but I'm considering a trial. My hesitation is that I set my system up to achieve sound reproduction that is true to the original recording. That's been my personal definition of the absolute sound so far. It seems to me that if the QOL effect is better or more realistic, then some similar process would have been applied to the original recording (assuming its a good recording).
