“Oppomod” linear power supply

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?

The 205 does have the linear power supply for the audio stage. That being said, upgrading the switching power supply of the digital section to a linear power supply will definitely increase the sound quality. In my experience, switching power supplies will create a glare (can be described as a "digital glare") to the sound even though it it only used for the digital "transport" section. A linear power supply will always allow the digital clocks to operate smoother without noise in the circuit. This can definitely influence the sound quality achieved by the DAC/audio board. I did a really long write-up of LPS here:

The OPPOMOD power supply is extremely well built and designed with large capacity Nichicon KW capacitors. The "Clones Audio" power supply looks very nice as well. It appears that the Clones Audio uses a discrete regulator section (as opposed to the monolithic LM78xx/79xx regulators on the OPPOMOD). The Clones Audio also uses a Mundorf electrolytic cap, but only at 10,000uf. I think the OPPOMOD will have a large capacitor bank (probably around 40,000uf for 5V section). Both will probably do well, but knowing what I know about digital sections, I would go for the larger capacitor bank to ensure the smoothest DC voltage.
