AudioPrism CD Stoplight & Auric illuminator work?

I have had quite a lot of experience with the CD Stoplight.
It's what I would call a 'trade-off' tweek. That is it improves some areas to the detriment of others. I suppose I
have tried most of the tweeks out there and have found the
Mapleshade items to be the best. This is with the exception
of the tube anchors which sonically are wonderful but act
as a dutch oven over heating and shortening the life of
the tubes.

Auric Illuminator works for me. Also great on DVD's. It goes right to the worst digititis, that hardness and glare in the upper mids and low treble. It is not as expensive as it seems because it treats so many discs.

Heard several recommendations in favor of Auric Illuminator so I decided to try it myself. The spray alone hurt the HF attack transients & softened prettty much everything across the band. The marked pen made the HF's quite strident & unpleasant. Combination of the two effects was not what I wanted either, so I cleaned it all off & was much happier with the stock CD. Others have reported that the process worked well enough on poorly recorded discs that they liked it as an occasional band aid for those certain "challenged" recordings.
