I want to share the schematic. It's easy and could be built on protoboard pretty easily. I hope to offer the PCBs soon

Nice one, only just read the text on your website, but with respect to the "audiophile" remark. The "mosfet and fat resistor" class A approach is widely used in audiophile circles. Nelson Pass did a whole series on class a DIY amps, and there's this headphone amp on headwize too:

I really like this one too:

It sounds great and you can build it with parts any DIYer ought to have lying around.

You really can't beat the sheer simplicity of the MOSFET amp though.

Nice one, didn't know that one, I suppose if you exchange the 2n3904 for something like bc327 you might even get decent power from it.
