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!

Has this technology shown up yet in car and TV audio? I thought that was an intended market segment.
Jon2020, I don't see the ads in the magazines anymore, so I also wonder what happened.
But, I'm still using the QOL.
Using the qol on pre outs on your amp would require another amp for the power.
They closed down...i wonder why? i just grabbed one for $800 in mint like new condition and i'm loving it!!

I don't understand it either. I took mine out of the system for a few weeks thinking I could sell it.

But, just before accepting an offer I put it back into the system for one more time. Whoa, I couldn't take it back out!

I think if QOL would have added a volume control it could have been sold as a full preamp and would have been more in demand. Add on boxes sometimes are a pain.

Too bad though, great, great product!
