Light reflections disrupt the sound

Even high-end equipment for the highest of demands is powerless against light scatter in CDs. Laser beams are reflected numerous times and stray this way and that over the CD's surfaces. This audibly affects the reproduction. The sound loses its clarity and transparency. The beam diffusion cannot be avoided by error correction.

Does green or black work?
A hot tip in audio expert circles is the colouring of the CD's edge with a felt pen, to absorb the light scatter. The effect unfortunately doesn't deliver on its promise. Green as a complimentary colour to the red laser should bring better results, this is however often not the case as many lasers work with the infra-red spectrum.

Simple and effective: the 36? bevel- Turning round and absorption
In exhaustive tests biochemist Dr. Erich Schrott and engineer Wolfgang Schneider have looked for ways to eliminate the disruptive reflections. They found an amazingly simple, yet highly effective, tuning method. The CD's outer edge is bevelled and works as a trap for the light scatter. Black colouring absorbs additional misrouted laser light. An edge angle of 36? brings audibly the best results.

I'm sure light scatter is a measurable occurrence; I wonder if the difference between an untreated CD and a beveled CD is audible to the average human ear. I seem to recall that the Green Magic Marker did not stand up to double-blind testing.

Really? Where was that test published?

Fukt if I know, man, this was ten years ago when the Green Magic Marker thing was going on.

I can't believe anyone cares enough to waste money on this nonsense. Even IF there was a measurable difference, (note that ALL this stuff is anecdotal) this is some serious hair-splitting. I mean, the format is only 16 bit to begin with - it's not like CD's are immensely high-fidelity compared to what's BEEN possible in digital audio for the last decade or so.

But hey, if people want to flush their money down the toilet, why should I care?

If what you say is true, then everyone should be using the SAME converter because there is no difference. Let's face it, the difference between converters is hair-splitting. They are all good- arent' they?

EXACTLY what I was thinking. I'm way more curious about the demagging discussion happening right now.
