any good tweeks for marantz sa 1 sacd player

Getting the sa 1 this week . Was looking at isolation devices , cones , stones , drones . you know ; the fun stuff. What about Symposium ultra and rollerblocks? What about top support ? I already have an Elrod pc going on it. Would Shaki stones on top work ? Any suggestions would be appreciated greatly . Thanks in advance
The only tweak I've done to mine is place it on a Sistrum rack. It sounds wonderful, along with all the other equipment I put there. There are mods available from Reference Audio Mods that I've seen advertised here, but I haven't gone for that expensive option.
