CD Player Tweak


After seeing an episode of Steve Gutenberg, and reading a multitude of experiences on the interweb, I’m planning on trying what might be the most common audio tweak in existence: Lining the inside of my CD player with $20 worth of dynamat. Praise for this tweak seems to be almost unanimous. Better sound for only pennies.

The thinking is that the dynamat deadens vibrations and that less vibrations equals better sound. That line has a certain surface appeal, it seems to make sense. But one question is nagging at me and I’m hoping to get an answer before I break out the screwdriver and void my warranty:

If this is such a good idea, so common sense-ical, and so cheap, why didn’t NAD (or whoever) do it first?

I bought Noica for my upcoming project. $12 got me enough to do 8? 10? CD players. Maybe NAD raises their prices by a buck. I don’t think that’s what’s driving their decision. 

Why is Noico hard to apply? Or take more time than the average stuff?
I have found out that cd players are mostly affected by better support and less by adding any dampening sheet. But if you want you can try EAR dampening sheet from Parts Connexion.
Top and bottom cover for start and if you go crazy add small pieces of it on top of power supply capacitors. 

I use a specific paint I mix with added minerals to control resonance rather than damping sheets or the like which reduce soundstage air and size. Tom
As @petg60 has said, the footers can make a nice difference. The first tweak that got my attention were footers under my CDP. Cost $2. The tweak...Pumice Stone. It's used for pedicures. You can find it in the health & Beauty section of many stores. I was a skeptic about tweaks until then. Now I use my own DIY roller blocks. I can change the sound with the different materials used for the balls. Wood is my choice.
As to why NAD or someone else doesn't do the dynamat, it could be that they don't believe in it. Or the cost factor
I use a Gutwire Notepad on top of my components.  Damps out vibration without gluing anything inside.  Don't know if they're still made.
