This was reviewed briefly along with other cd-enhancing products in audio musings magazine, issue 14, 2001 (web address: audiomusings.com). By a small margin, it was preferred to some of the other products, including auric illuminator and various edge marking pens (the audio desk includes a black pen, so the effect could be due to the pen marking or the bevelling of the edge - thiey did both on the same CD as instructed). However the differences were so slight to the listeners that it was pretty much a toss up. I doubt "ABXers" would find the test very compelling in design although of course the result, that there were few if any differences, would please them! Cheers
