Anyone HEARD the qol 'signal completion' device?

Marc, any more experimenting with placement in your system? (before pre, after pre, etc.). Any effects on tonality?

I will be testing position change this weekend. In previous test, within my system,placing qol before the pre there was marked drop in air and soundstage. After talking to Larry Kay and telling him my experience he confirmed he also heard improvement after pre. I am fairly sure that is the prime way to go, but I will try 1 last test now that the new Cardas Clear IC is broken in. Marc

I have been having some friends over, but the rotation was so heated i could not justify a slowdown in the action so that i could do a cable swap. All comers spoke more than once that it sounded better than live to them. We know this isn't likely, but you get the point i'm sure. Upon taking the qol unit out of the circuit, all the excitement diminished. I will get around to swapping cables soon. Marc PS Setonaudio, what is your feedback?

Marc,

I concur with your findings. I no longer do sound test but rather just run Qol during listening sessions. The way I see it, it is like going to stereo...once listeners got over the paradigm shift, it just become the completion of the music and how it should be heard.

Once very nice extra feature is that the room acoustics now play less of a role. This is great for problem and odd shaped rooms.

I've heard the Qol on several different systems now, including Maggie 3.6, Apogees, small Gallo's and Pipedreams.

I can say, in general, I didn't like what it did to the panel speakers. They are already capable of producing wide open sound. The QOL was a bit too much of a good thing, and you can achieve the same presentation on these with proper setup and room treatment.

However, on cone speakers the QOL was very nice indeed. Those little Gallo's sounded like floorstanders and filled the room. On the Pipedreams it made the presentation far more expansive.

So overall, YMMV depending on the type of speaker system you are trying this on. And yes, the price point of this puts it out of reach for many people, and no I have no idea how it works except that it must play with phase. That means it is probably not a device for the purist audiophile, but more for someone who just wants things to sound good to their ears.
