"Tuning" CD's


Shaving Compact Discs to improve the sound (?!)

This Youtube will trigger the usual chorus of self-appointed audio rationalists, but I have a much simpler workaround that involves simply sanding the edge of the CD and then blackening the edge of the CD with a magic marker - all in the service of nullifying incident laser reflections bouncing off the glossy edges of CD's.

The results were so impressive that I now perform this procedure on all of my CD's. I should add that my system plays CD's only which are burned from downloaded flac files. The files are converted to .wav files in JRiver and burned at the slowest speed my desktop drive can achieve.

Please let us know what the you hear or do not hear.

I should also point out that the sonic graphs displayed the the Youtuber for comparison between the treated and untreated CD's are not symmetrical if you look closely.

I’ve many green edged CDs, but I must admit that I view CD players and transports as unnecessary when you can do bit perfect rips that are played by a high quality server/streamer.

@tweak1 I have an Esoteric SACD player.  Esoteric states in the user manual do not use any type of tray matt or insert.  There must be a good reason for them to state this? 

@bigtwin 

There's always an exception, but I would first check NDM out then ask Esoteric. Hard to imagine not being able to use NDM unless you have a slot load player

@bolong "blackening the edge of the CD with a magic marker - all in the service of nullifying incident laser reflections bouncing off the glossy edges of CD's."

New Dark Matter "The color black is ineffective for absorbing infrared light; for CDs black is effective only (rpt only) for the inner edge. When black is used for the CD outer edge or the CD label it hurts the sound"

Guess one of you is wrong.
