Just as an aside, at one point was running Auralic Vega dac and some other streaming devices off battery PS, lower noise floor, lost dynamics.
I have custom build streamer assembled by some of the leading members of that forum, I added JCAT Optimo ATX LPS. This was their top end diy design prior to the Taiko Extreme clones. Unfortunately, I2S output at the level of Gaia not possible, real estate issue. The XDMI interface in new Taiko looks to be a game changer.
