Modding a Oppo 103

I recently bought a used Oppo 103 from the Bay to tinker with a few SACDs of jazz albums I couldn't find on Tidal or Qobuz. This was a deliberate purchase as I wanted to use the HDMI out into my Bryston BDA3 DAC. While the HDMI route works and plays back native DSD, I'm wondering whether the Oppo can be improved. I've read some older posts on various audio sites about modding the PSU that can level up the sound quality. I came across this: OPPOMOD. I was wondering if anyone has experience in this area? More importantly how likely will the sound improve if I'm already bypassing a lot of the Oppo internals and using the Bryston DAC?  

Thanks!

I used to have an Oppo 93 with Exemplar mods, it sounded very nice for the money. I believe it had the usual stuff like power supply upgrade, nicer opamps, all the regular mods that different companies did with Oppo players over the years. However I think it almost exclusively helped the analog outputs. Because I never noticed an improvement when using the 93 as a transport with external DAC. Granted I only ever tried coaxial digital out and not HDMI but one would think the same applies for both.

That Oppomod power supply is $380 so not the end of the world if you wanted to experiment. I just wouldn't do it expecting major improvements as you might be disappointed.
