Have you ever wondered why so many CDs sound thin, metallic, dynamically compressed, bland, generic, congealed, uninvolving, whimpy, electronic, analytical, two dimensional, lifeless, distorted, sour, synthetic, rolled off, thuddy, strident, and like paper mache? All of that is about to change.
New Dark Matter NDM, the newest product from Machina Dynamica, is the only audio product that absorbs both visible scattered laser light and invisible scattered light in CD players, thereby improving optical signal to noise ratio, thus improving sound quality. The CD laser nominal wavelength is 780 nm, which is about 80 nm longer than the longest visible red wavelength, 700 nm. The laser is not monochromatic but has an effective wavelength range of around 650-850 nm. This means most of the laser light, and scattered light, is INVISIBLE. The portion of the laser light below 700 nm is visible red, presumably as a safety feature.
The scattering of the laser light occurs when the laser beam strikes the physical nanoscale data on the CD. Then, scattered light reflects off surfaces inside the CD transport container, lighting up the interior like a Christmas tree. The Green Pen and other similar audiophile products (including our own Codename Turquoise tray treatment) affect the sound because they absorb scattered visible RED light. But most of the scattered light - around 75% - is INVISIBLE and not amenable to absorption by ANY color, including green, turquoise, or even black.
