Potting a Denon dl-103r

Also, a "potted" cart has nothing to do with 'gluing" the body of the cart to the carrier.

Can you please elaborate 

So What is Potting and Why Bother?

Potting of cart bodies involves applying an electrically inert compound to the cart internals to minimize unwanted resonances of the internal components.

Potting a 103 has been, IME, a great tweak and well worth the effort. As a matter of fact, I found running a 103 nude with a carbon fiber top plate and potted to be the best version of this over achieving cartridge. And, yes, it sounds better than most under $1000.00 cartridges and some over that price point.
