[sdiy] OT: Scratchy CDs

[Michael Boracci]

Well I am either going to contact Larry Crane ( editor ) of TapeOp who is
very cool and ask him to help me find that article, or re-read many copies
of TapeOp to find it.

I have a piece of Behringer equipment in my rack ( $25.00 clearance sale at
Guitar Center, couldn't pass it up), called the Ultramatch "Jitter Remover".

Jitter is one issue here which is non-mechanical in nature, however, I know
those audiophile freaks ( I don't mean that in a bad way actually )use all
kinds of isolation products to remove the effects of mechanical vibration.
They even wax the caps to the board to keep them from vibrating. In addition
they stick thin lead sheets on everything inside the mechanism of the cd
player to absorb vibration. If these people can hear the difference, then
perhaps our crude burning environments need a little tuning-up for better
results.

Just a thought.

One minor point: A CDR contains not metal to burn, but rather an organic
dye.
