Simple High Performing Headphone Amp

So after gathering dust for several weeks, I finally completed my though-hole version of this awesome amp.

Dead quiet, kickass bass and excellent dynamics. DC offset is around 5mV on the left and 7mV on the right - pretty decent.

Thank you TimS and XRK!

Hi Donthertzme,
Nice through hole boards. Any chance you can share the PCB lay out!

It’s a public design so you can post if you want. But if folks want a ready-to-build version that has a low noise PSU already, check out the JPS64 layout over in the GB thread.

Simple High Performance DC Coupled Class A HPA with sub PPM THD

Here are the Eagle layout files. I've included 2 versions - the one you see in the picture (100 X 85mm), and one with more readily-available standard SK104-style heatsinks (85 X 85mm). Let me know if you'd prefer gerbers.

I left out the power supply so I could try various power options. But JPS64's complete version is also very good.
