Anyone HEARD the qol 'signal completion' device?

Roscoeiii,
I agree the only sure way of evaluating a piece of equipment is to try it in your own system and room.
All other remarks are just unsubstantiated opinions.

Someone mentioned on another thread about the H-Cat Preamp and was comparing it in there opinion (without trying the Qol) to the Qol unit.
My comment to that is, a few years back I did buy the H-Cat Preamp but I could not detect an improvement so I sold it.
I am going to use that same process with the Qol.

Haven't heard it, but in my past life as musician, I have heard many devices that can make a piece of reproduced music nicer to listen to - Aphex Aural Exciter for example, although that device is very old by now and I'm sure there are plenty of new items available in the studio to spice up a track. In general, these devices worked by manipulating the eq and phase to make things sound bigger and more present. I read the review of this device and the interview with the designer and I don't doubt for a minute that this gizmo may well make an audio system sound more pleasing. But I do have a hard time with the "unlocking hidden phase information.. etc" concept. I could see if this device followed the microphone directly in the recording chain, but once the music is recorded, I can't understand the concept of "hidden information" that cannot otherwise be unearthed through playback on the same device on which it was recorded. I realize that audiophiles claim to hate tone controls and DSPs, so from a manufacturing standpoint, it is much more paletable to say you're just uncovering what's already there than to say you're manipulating the signal. Again, I won't say it doesn't sound good or that what the designer is saying isn't true. I just don't see how it's possible. Once something is recorded on a 30 ips tape (for example) I cannot see how that same recorder is failing to play back intact what it just recorded. Enjoy.

To build on Chayro's post, I have an SPL Qure parametric equalizer which has the Qure processor. In addition to the normal 3 bands of parametric EQ the Qure processor messes with the signal's phase and adds a mid/hi boost which is intended to clarify vocal/instruments and reduce digital harshness. It also adds around 1-2 dB to the signal. I personally don't like the effect and never switch it into the signal path, but if is definitely noticeable.

I'm not saying that the SPL Qure is the same as the QOL device, but just pointing out that phase manipulation devices are fairly common and do have a sonic effect.

When in active mode, it changes the amount of gain, making it nearly impossible for a true A-B.

Well, I am expecting much better results from the Qol unit than the last few posts have described.
I'll just have to wait and hear it in my own system this weekend.
