Favorite CD treatments?

I'll definitely second you on Herbie's mat, Spencer. Interestingly, it's not that great on SACDs (at least in my changer, the fabulously cheap (and fabulous!) Sony DVP-NC685V). After a little experimentation, an Audio Prism CD Blacklight is the best so far in that system. Don't know why, it's not that great w/CDs...

The only treatment that I've heard an unequivocable improvement on all CDs treated was the use of an edge trimmer that bevels the edge of the CD. An expensive device, and one that I don't plan on getting until data is in on the long-term effect on treated CDs, but it does work.

The product that Larryi is referring to is manufactured by Audio Desk. I have heard redbook discs that have been beveled by this device but recently here on Agon someone mentioned that there might be less than satisfactory results with hybrid discs.

I use the Mapleshade Ionoclast gun. I zap the CDs. It increases low-level resolution. As a result the system appears to be more sensitive and plays louder to the observer. For me it really does work. About $40. I haven't tried the other stuff yet.

I second Tindersticki on the benefits of AudioTop digital, but there are several additional benefits, such as the Audio Desk trimmer with black edge coating, and the Furatech demagnetizer.

I have been using the Audio Desk for years. There is no problem with it using it on cds, sacd, sacd hybrids, dvds, or dvdas.

Each tweak adds significantly to the realism of the sound.
