Oppo 203 setup/tweaks


I auditioned then purchased an Oppo UDP 203 having had the BDP 105 for some years.  I first resolved that the Digital Filter setting was critical for best audio performance  that setting being the 5th, super slow (roll-off rate).  I have found setup/tweeks to be very important in maximizing performance and would like to get personal experiences specific to this player where improvements were made.

If you're using an Oppo 203, the best upgrade you can make - and the first place you should look - is to replace the switching power supply (SPS) with a linear power supply (LPS).  It's a 15 minute direct swap with a screwdriver and no "tweak" will come close to the upgrade that an LPS will make in performance across the board, whether you're using the analog outputs, digital outputs, or using it for movies.
