“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

Very interesting tweak. I’m actually thinking along those lines. My AC power conditioning allows the lower noise floor of the 205 to be fully revealed; also the fact that finer detail can be much better. I’m thinking perhaps of a Berkely Alpha 2.  Do you know how it would compare to your new unit?
