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!

Having heard it after 100 hrs of break-in wanted to get experience from others who have had it longer. What I am hearing is in the by-pass mode the sound is "veiled" and dose not reflect a true " un-QOL" sound. When I removed the QOL from the system the sound was much better from the by-pass mode and in my ears not that far different with the QOL in the "chain". So, a better comparison may be QOL versus non QOL rather than "bypass". What say you? Thanks.

As of yet I am not hearing that big of a difference with the QOL compared to my regular system. I do have it installed between the preamp and amp. My system is approaching $250K so subtle differences are easily revealed. I would like to hear from others who are on the "fence" as to what they were hearing that convinced them one way or the other to keep it or return it. Thanks Ron

At the suggestion of Pipedream, I installed the QOL after the source whereas before I had it between the pre-amp and amp. That one change has made a great difference in the overall presentation and enjoyment of the music. My amps, preamps are Ypsilon ( very resolving). So, any difference to the sound is very noticable. Yet, this QOL has changed the sound I think for the better. I haven't lost the resolution yet some "presence" is now apparent. Got just over 250hrs of breakin and ordered the Hi-fi supreme fuse. The jury is still out but now leaning slightly on keeping it. Have about 2 1/2 weeks to decide. I agree with both points of view about the merits of resolution and musicality. thanks Ron

From my phono preamp I feed the output interconnects that would have gone into my preamp and feed them into "input 2" or any of the other inputs "3" or "4", on the back of your QOL. The "output 1" serves as common "out". On my remote I push In2,3,or 4 and I have the phono stage kick in. Hope this helps. Ron
