I’ve done extensive mods to it, I’ve detailed what I did on a UK hifi forum here:
1 Linear power supply with circuit breaker installed rather than fuse.
2 Dampened inside of case
3 Replaced thin sheet metal BD Drive mechanism cover with thicker aluminum
4 Fitted i2s output board for direct connection to Directstream i2s input
5 Upgraded system clock with OCXO Femto clock board (in progress…)
6 Silver wired Furutech IEC Inlet
The mods cost more than the player, but worth every penny for improvements to audio and video. The Oppo as a foundation to build on has seriously untapped potential.
Getting the best of the upgrades with i2s Directstream connection, really bringing out the best of what the Oppo can do now.
Love the fact that it acts as a Roon endpoint and can output as i2s, an improvement over the Bridge II in my system.
