While there is much better and more expensive devices I found a combo of pico feet under and vibrapods on top of trap quite an improvement along with my mapleshade platform on my oppo.I would experiment with top and bottom vibration control by the transport of your oppo.
Best vibration isolation device for cd player?
Feet or platform. I have a modified ModWright Oppo BDP 95 cd payer with external power supply. Thank you for your advice!
