Why green ink works.You have seen it again, and again. Use a green felt tip marker, and paint the edge of the inside, and outside of the CD. The sound improves, but why? Or is it a placebo? It’s too cheap to be called snake oil, except if you happen to see some kind of “audiophile” green felt tip for $19.95…then worry…
Disclaimer: you must have a revealing system and decent recording to begin with, as my other posts have stated.
Level of effect: on a less expensive CD player: NOT subtle. On a better built CD player: noticeable. The effect was pronounced on a 1993 Rotel cd-p, less pronounced on a 2003 Naim cdp. But noticeable in both cases.
What will you hear: you should hear
much more ambient detail, decay, small things, and the soundstage should be deeper, not on a single plane.
Why does it work?Optics. The laser mechanism has to track, and fix errors
on the fly. The power supply switches on and off as it does its work. The laser information that is picked up isn’t just bumps and pits; it is also
optical diffusion, surface scratches and other anomalies.
The green ink helps absorb the refracted light artifacts much the sameway sound proofing absorbs reflected sound in a room. The result is: less noise and error, and a cleaner signal.
It works…try it! It costs you very little, and can really make that $400 CD player sound like a $1,200 CD player..
