I also use Herbie's Tenderfeet to great effect. Another option is Sorbothane hemispheres. If you google Sorbothane and get to the Sorbothane website the info. there will guide you. My guess for a Denon CD Player would be 3 or 4 30 Durometer hemispheres would do the trick.
There are many audiophiles who are Sorbothane detractors...don't be misled by anti-Sorbo. buzz. If you buy the right Durometer Sorbo. and mass load your player appropriately, the Sorb. can yield great results for little money
