Anyone HEARD the qol 'signal completion' device?


An ad in TAS... touting this box. I remain skeptical but would like to know what your impressions are if you have heard whatever it does!

yeah, my Luxman has a preamp out. But wouldn't just hook up through one inputs on the Luxman (source>>>QOL>>>Luxman)? I mean, why use tape out or preamp out? I don't get it.
Koestner, creative thinking; I like that. I suggest you do that experiment. Let us know if you fry out anything in the signal path! :)
I don't have one, let alone two of them. I would think one of these dealers could do this. I also don't see the risk of "frying" anything by hooking up two line level devices, that reportably have no gain, in series. But, you never know, so whoever does this should wear a fire suit.
