Anyone HEARD the qol 'signal completion' device?

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?

I have the QOL on the way. I will try and post my impressions after a few days.

After having experienced the Qol, AND reading reviews...I'm excited.
This is/could be, the straw that stirs the drink for music reproduction.
After all the bullshit, the Bose, the Polk SDA, the stuff we audiophiles are trying to forget...we come across this...the Qol. The name sucks...but the product is a step beyond...it's the Telephone, Xerox copies, Xrays, Core memory (think computers), Polaroid Cameras, Guttenburg Printing Press...Internal Combustion Engines...you name it.
This...is the next phase of audio as we've known it.
