Green-'ening' CD's

In another post on CD of marking CD's. In particular, he mentioned that marking CD edges increases the read error rate. He concludes this is bad.

While I don't doubt the accuracy of the investigation, nor the assessment that increassed error correction means a deviation from the intended signal, I do question if this is bad, per say. I base this on the audible improvements that many note by employing this tweak.

I hypothesize that the increased error read rate acts as a dither effect - something used in the Rotel 991 (?) and some other players with a positive sonic effect. Even if my hypothesis is rejected (probably by the next post :), it is still odd that a decrease in signal integrity leads to improved sonic performance (according to many). I would be curious what the group thinks about this.

Don't know what happened to the first line of my post. Meant to be:

In another post on CD treatments, in particular, marking the edges of CDs with a green pen, Sean mentioned that such markings can increase the read error rate. He concludes this is bad....

Rest reads as above.

Well, there are three possible explanations:

1) Sean's technical explanation is wrong.

2) Some audiophiles prefer an error-corrected signal to the "original."

3) Some audiophiles imagine an improvement that isn't really there.

I would guess that the increase in error rate would be minor, but I haven't tested this. On the other hand, there is no other known or even scientifically plausible reason why marking CDs should have any effect whatsoever on the signal. (Your dither theory being a fine counterexample.)

You're asking for a technical explanation. There is no technical explanation. If you believe that marking your CDs makes them sound better, then mark them. Leave the science to the scientists.

Bomarc,

I'm inclined to take you up on #2 :-) Not looking for *only* a technical explanation as I know there may not be one. Still, there are plenty of bright folks who are part of this forum who's opinion I'd like to hear. If it is a 'dither effect' then there are some interesting conclusions/implications which may be drawn.

This sure isn't intended to be flame bait :-(

Best,
