The Ultimate Sound Improving for Compact Disc's through Patent-Pend.CD Sound Improver
 

This approach based to a strongly reduced light scattering.
I have heard about this, but never perform own tests (risc of damage of compact disc after short time)

And two additional CD sound improver I have found on the web - based on a CD degaussing:
1) Degausser "DE2" (DE 2) from "Stein Music"
2) Furutech RD-1 (RD1), RD-3 (RD3) and RD-2 (RD2)

Are there already some experiences?
Thank you for your comments.

Do you have pictures of the suckers who bought this stuff?

1 = 1, 0 = 0. How would this "sound improver" affect that?

It makes the ones more one-like, and the zeros more zero-ish.

The other stupid explanation I've heard is that it reduces the demands on the laser servo. No decent back-up on that, nor any even vaguely reliable data showing an effect on the analog output...

The edge beveler, a new spin on CD tweaking. Amazing, this stuff just keeps coming. The review starts out great too, "After all, I had already found that just about anything you did to a CD was likely to make it sound better".

You guys just never hooked one of those suckers up with the right wires. ;)

That edge beveler thing costs 1000 dollars :eek:
...and he claims to have sold 1000's to happy customers :rolleyes:

I think if I wanted to test the effect (which I don't), I'd start with a piece of sandpaper and a laundry-marker.

I'm not defending this overpriced product, but have you guys ever noticed how out of balance cd's are? I'm guessing the device will true up the disc edges. This in turn should mean less wobble when the disc is spinning inside the player. I'm sure something could be constructed to acheive the same for far less.

As for degaussing the disc? how does that work? Less static? cleaner surface? Does the charge being removed by the degaussing process interfere with the laser? All seems a little extreme for me tbh!;)

Don't you guys know about Exact Audio Copy ?

Have you tried using it to rip CDs onto harddisk ?
Do you notice how often (if at all) you cheap 10-Euro CD-Rom read your CDs with error ?

Want holy digital copies ?
Rip and store them in solid state memories.
