Anyone HEARD the qol 'signal completion' device?

Ozzy, thanks for the review and impressions. I am glad you are enjoying your Qol. Thanks to all who are also posting.

To address the cable and room treatment comments, I will give my experience as a dealer and from my personal experimentation.

Good cables will always help save the purity of the signal path and reduce noise in a "busy" system so use good discretion and set a budget for these items.

We have played with room treatments with and without Qol in the system. As always first order reflection issues should always be addressed, if possible. This may simply be for good measure or imperative for very difficult rooms. Without Qol, with and without these treatments, the difference is very noticeable. I am not telling anyone on this high end forum anything new there. With Qol, we have found that these treatments become much, much less of a consideration. In many cases, they made little to no improvement so they were simply removed from the room.

In difficult rooms, Qol has also made a nice improvement. Be it an asymmetrical room, odd construction, or dealing with the Wife's firm position on how much real estate she will give up for your crazy science lab, Qol has helped to improve these setups. By taking much of the room out of the equation, these difficult scenarios have become less of a headache.

If any of you are in the San Francisco Bay Area and would like to audition in our shop or in your home, please feel free to give us a call. We would be happy to give you a taste of Qol. setonav.com 510-279-2600 Or, if you are in other areas and would like to simply speak about the technology, we would love to hear from you.

The point on cables is a good one. I was fortunate to have an extra pair of balanced cables that were the same that I use throughout. Adding a different cable for the Qol will result in the sound being different than what you are used to hearing. That in itself could lead to thinking it is bright or colored sounding.

But contrary to what others have posted, I think the unit needs some break in time, just as every other electronic components does.

Setonaudio have you tried it between source and preamp?

Yes...we have experimented both ways and actually run it both ways on different sets up we have.

For our setups...again, this is for our specific setups. We run Qol behind the preamp in our higher end room with Cary FE211s tube amps and in front of the preamp in our more affordable setup with a Cary 200.2 solid state amp.

There are many reasons as to why one may feel it sounds better in one position or the other. Some reasoning may be scientific, some may be physiological, and others mental but the reason an audiophile should place it in one place or another should be governed by what makes your ears happy...."Listen to your Ears!"

V.curious about this thread. I've just installed a Black Hole (see my thread in 'loudspeakers') unit by SpatialComputer which has opened up the ambience and lowered the noise floor in my room, increasing dimensionality akin to surround sound, and this unit threatens to do more of the same.
On 6Moons a unit called NeutralAudio X-Drei seems to promise the same benefits as the BSG.
Any opinions on this unit?
