Favorite CD treatments?

I use Kleenmaster Brillianize to clean CD's. Just spray on and wipe off with a microfiber cloth. Leaves no residue and sounds better. Much less expensive than audiophile cleaners/treatments. Most hardware stores carry it.

My Empirical Audio music player with an outboard optical drive and sophisticated programing has made treatment inaudible on playback from my hard drive.

Cream Electret, Xtreme AV Liquid Resolution, Red X Coordinate Pen, Cryo or home freezer, purple pen around outer edge/black pen around center hole.

Geoffkait, no Audio Desk edge treatment or NESPA?

Tgb, no Nespa, no Audio Desk. I had a pseudo Nespa for a while - an adjustable and powerful strobe light. (I like photon canons a lot.) I used to have the Intelligent Box, another photon canon. I use the Quantum Clip on CDs and Red Sharpie for the outer edge of all Mercury Living Presence CDs, the ones with a black/white label. Oh, and the Walker's Talisman demag thinggie and Mapleshade's Ionoclast. I also happen to be a big fan of Monster Cable CD Rings.
