Anyone HEARD the qol 'signal completion' device?

Seton, that's a great endorsement. I agree the only way to know is to order one and hear for oneself in a known system.

What you describe is pretty much the improvement I experienced when Jim Smith came to voice my system. He added nothing, but the sound became much more real with careful and deliberate positioning of speakers, listening seat and treatments. Tone, dynamics and presence all improved dramatically. Then adding isolation to my front end components took it to the next level.

The total was about the same as the $4K for the Qol.

I guess the Qol is an active approach while what I did was passive. Interesting that the results seem similar.

Do you think that the major electronics companies will start to license the technology and insert it in their products? Pass, ARC, Krell, Atmosphere, VAC etc?

Peterayer, The Qol will be in addition to the isloation you've already done. I would not call it an active approach.

Ozzy, The device is in the signal path and adds gain. How is that not active?

Room treatments, speaker and listener locations are certainly passive. Adding isolation, racks, cones, feet etc is also passive, IMO.

Peterayer,

I agree with Ozzy, this would be in addition to the tweaking you already did but to a much larger scale as what you did is not correcting phase.

There surely is a noticeable volume increase when Qol is engaged but it does not sound like when you hit the "Loud" button on your car stereo nor turn up the volume but rather it sounds like you are listening to more information. I would compare it to only playing one channel of your system,(Qol off). When you turn on the second channel, (Qol on), the rest of the music is now delivered and the signal and music is complete. Did you turn up the volume? NO...you simple delivered the rest of the music that is on the track.

I do see this technology moving its way not only into other hifi preamps and processors but also into the consumer market using the lesser digital algorithm of the technology. I think Larry Kay (Audiophile and HIFI enthusiast) will keep the highest quality analog version in the high end market. From a business sense, the hifi market is likely the low profit side while the licencing the digital algorithm to the consumer market is where that company will really prosper.

Less is more. Enough said.
