Don't know the RCD-1072, but in general brass footers work particularly well under CDPs, preamps and amps. I've experimented with lots of footers and the Mapleshade Heavyfoot V3 are the best bang-for-the-buck footers I've heard.
No need to remove original feet, just place in a roughly triangular arrangement under the equipment and in direct contact with the bottom of the chassis. I usually place one of the footers under the heaviest part of the equipment and distribute the other two to balance and stabilize the equipment. With a CDP, I also like to place a footer directly under the disk tray. Improvements include more articulate images, improved dynamics and musicality, and, significantly defined bass.
