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 those are all options for placement of qol unit. Just choose the one that works for you best. For me after the pre-amp was better. If you put it before amp you will only have qol working for that one source. after pre-amp all sources have option for qol.
I finally took some time and listened to the mono set of the Beatles on cd through the qol unit. I set ARC pre-amp to mono and qol to mono. The improvement is just as profound as with stereo. You have to hear it to believe it.
I've been reading this thread with some interest; especially after reading Robert Harley's review recently. I've been curious about adding room 'tweaks', either the Syergistic Research ART system of bowls on wood blocks; the Stein music harmonizer system, or this product...seems like they all have supporters, but only have funds for one of them. How sensitive is this device to interconnect cables? In other words; have you used identical quality cables from pre-amp to amp; and added identical set for the qol device? Does it reflect different quality or brands of IC's, or is it pretty immune to cable influence? Same with power cords? I'm just thinking about the total price of admission to this dance; $4k for the device; $500-$800 for quality balanced 1 m IC's; and $400 for a power cord; makes it as much as a new DAC, or component. If I jump; I'll probably place it between preamp(tubed VAC) and solid state mono blocks...any issues with impediance matching? Thanks. Looking forward to hear from other people's experience...as I have problems in my room itself; that this might help solve.
On the BSGT website there is an oscilloscope reading of a mono audio signal before and after the QOL process. Clearly the after picture is no longer a mono signal. Could somebody please explain.
Mribob, I have the Stein system which, per tweek geek, is better than Art system. I have the Bybee speaker bullets and 2 of the quantum qx-4s by QRT. From my seat the qol by far made biggest improvement. As far as cables there is some improvement nothing big. Was told by Larry Kay cables were not big on list. Lastly the qol seems to take the room very much out of equation.
