Oppo UDP-205 Op Amp, Linear Power Supply

I suggest that before you do surgery (or spend a lot of money otherwise) on your Oppo that you consider letting the Oppo feed an external DAC.  First of all, any modifications, unless they are easily reversible, will kill its resale value.  Also, it has never been very hard to find a DAC at a reasonable price that will outperform the DAC section of the Oppo.

I bought the linear power supply from a guy in South Korea, and I think it is major improvement. It was a direct drop in replacement. I also have mine plugged into a Bybee and Niagara power conditioners. And I have Stillpoints ultra SS underneath.

Like Ozzy, I installed a LPS SE from oppomod into my 203. (One is available for the 205.)  I installed an Orange SR fuse and will be installing an Audio Magic Pulse Gen ZX soon. The LPS mod is plug and play and very easy. Perhaps the most improvement resulted from plugging the Oppo into my Shunyata Everest power conditioner.

PS I have no affiliation with oppomod but am a happy customer.

Clones Audio is a very respectable vendor for what you seek:

Scroll down for the OPPO mod and you'll also see the how-to video that accompanies the upgrade.

All the best,
