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’m not worried about which material to use. I am wondering why, if vibrations need dampening and it’s so easy and cheap to do so, doesn’t NAD do it in the first place. 
I use Noico dampening material in/on ALL my components.
Often in multiple layers.

It is somewhat costly and takes a while to do the job right.

This adds cost to a product.
One that NAD does not want to absorb or add to the retail price.
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.
