“Oppomod” linear power supply

I had that mod done to my 103 - astounding difference...air, life, ease, extension, clarity in spades.

I had done it to my BDP-103 and the improvement was worth it. It wasn’t OPPOMOD but something similar. If you want something that some would consider higher quality, check out Clones Audio. Funjoe makes a very high quality LPS and has a nice YouTube tutorial showing all the necessary steps to do it right.

I did it to my 105 to excellent effect, but now only use it to spin SACDs DVD-As...Maybe 5 months ago I bought a Audio Alchemy DAC/PRE just for the pre, but eventually tried the internal dac and was blown away by how much better it is than the 105s 

I tried one that was > $350, but had fitment issues as  well as getting it to work. I sent it back and replaced it with one for ~ $115, it is a huge upgrade, but if you listen to music you need a much better dac circuit than the 105 has
