I sold a friend my favorite cd player (Nakamichi CDC-200) and was very unhappy with my Denon DCM-444. I ordered spikes for my turntable and ended up using them on the Denon DCM. The difference was night and day. Without any question the Denon Woke up and performed like a different player. Totally accessing more music on the CD's than ever. I have Isolated my turntable, cassette deck, and reel to reel with the spikes. I built a new pair of speakers and added in a plate for adjustable spikes in them also. A DEFINITE MUST ON MY SYSTEM. SMALL ROOM, TOO MUCH BASS!
