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 anyone else tried the qol in their systems lately? It seems like this has gone off the radar for quite a while now.
Ozzy, I know you still like yours and I respect that. If it works well in your system, why not?
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.
