Ever think about using an external PS? As soon as I get mine, I'd like to take a look at this option. Disconnect the switched internal PS and use a Wall wart or STEPS to provide the analog power. May require cutting foils though

Looks good though!

I actually tinkered with injecting 12V into the USB power using the following approach, but couldn't get it working


USB...........................................DAC

probably because of that step up converter...it was seeing an over voltage condition.

That makes sense - thanks

Are there any other mods that might be worth considering?

the only ones I can think of are the caps and power supply. From what I've read, this is a pretty capable DAC. Short of changing the D/A chip I think that all you can really do. ....unless you believe better resistors would benefit...

I need to work on getting a better amp before I upgrade the EB01....it'll be a pointless effort otherwise.
