CD Treatment

Of course, the green pen can provide modest improvements. But improvements nevertheless. However, the problem is too great for only a green pen, gentle readers. Green absorbs the visible color red, it’s red’s complement. And red appears in the scattered CD laser light, so some of the scattered light is absorbed. Thus, the amount of scattered light getting into the photodetector is reduced. That’s the reason the green pen is audible. But, wait, there’s more. The red portion of the CD laser is only the lower 1/4 of the bandwidth. Since the CD laser has a wavelength of 780 NM that means most of the scattered light the other 75% is not visible red but near infrared light which is invisible. Infrared light is immune to absorption by green or any other color. That’s where New Dark Matter comes in, it absorbs all light, visible and invisible. Thr

Back when, I tried them all, and I never noticed any difference. Save your money for more music or better gear.

@fundsgon.  - I am a bourbon and wine guy as well. A triple threat 😂
i think it is very important to make sure the disc is balanced and your CD spinner is as level as possible. Also, be sure to put some weight on the top plate to lessen any vibration while listening. Many CD players are made from thin materials and “ring like a bell” when you tap on them. SimAudio makes a great product.                                     ** Good luck and happy Listening 👂🎶

Didn't there used to  be rubber bands that went around the disc?

Another tweak was to load a second CD on top of the first one. More mass - claimed to improve stability of the spinning disc. I never tried this, fearing getting both CDs stuck!
