CD Treatment

@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!

Regarding scattered light, didn't 47Labs have a CD player sans (without) case? 

Clark Johnsen, audio provocateur extraordinaire, published Lotions Eleven, Fluid Dynamics of the CD - a review of eleven CD treatments of the time - in Positive Feedback. Among the sonically intrepid other methods of CD treatment include demagnetizing the CD, freezing the CD in the home freezer 🥶, de-ionizing the CD, stiffening the CD, beveling the outer edge of the CD, sanding the outer and inner edges of the CD, leveling the CD tray, using Silver Rainbow 🌈 Foil on the CD, Cream Electret, painting the outer edge purple, painting the inner edge black.
