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!

Kclone, some integrated amps have a preamp out, if not, choices are after source or through tape in if available.
I would think that if this device is the "real deal" ie not some signal processor that most people like at first, then get tired of; which I am concluding from all the positive posts that it's not; then if one were to hook two in series the sound shouldn't change very much, if at all. The reason is if it restores lost info then the second one in series would have no more lost info to restore, therefore not changing the sound at all. Now that's just theory and I figure some small changes, but not like twice as large an effect. If the second one makes a big difference to the sound then it probably is just another spatial effect machine.

So if possible, can someone try two in a row to test this?
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! :)
