A blast from the past! elizabeth

I have not thought about AQ cd shine for a long time. I do recall seeing those ads in Stereophile circa 1990's. Never bought any though. It is amazing that this product still holds up in 2018.  Happy Listening!

Because i use the PS Audio DMP player,  some of these issues are not critical as it reads and rereads the info and then puts it into a cache. However i use this product and it seems to improve the sound a bit,  but of course it is NOT to be used on the optical side,  but only on the label side.https://nordost.com/accessories/eco-3x.php
