Opitrix vs. Walker Audio Vivid?


Can anyone tell me how these two CD cleaners / treatments "sound" on an absolute basis and relative to one another?

The other one I would be interested in hearing a comparison is the Auric Illuminator. All three products do the same sort of thing, but I have not tried the two you mentioned. Someone needs to do the "shootout".
From the archives here, there was a thread on this recently.

Not many responses, but those who have tried multiple products seem to favor Walker Audio Vivid by a wide margin.

I've tried Optrix (it doesn't seem to do much for me sonically but is a good cleaner). I've also tried Auric Illuminator (much better and gives a noticeable improvement in the sound of most CDs and SACDs). Auric is actually more impressive on the SACDs but cannot be used on hybrids manufactured by Sonopress.

Walker Audio is next on my agenda. More expensive than the others but supposedly yields a better payoff.
I have used Auric and Walker and find Walker Vivid to be the more effective product. I have never tried the Optrix.
Hello Wellfed:

Could you articulate the sonic differences you hear between the Auric Illuminator (do you use the black "CD Stoplight" treatment?) and Walker Vivid?

Also, I believe the Vivid is also a polishing agent ala Mapleshade Microsmooth. I have tried the Microsmooth and have noticed that slight "swirl marks" are very difficult to avoid, although I don't know if these microscratches have any sonic significance. Any comments?
