This project is a bit different from those I normally put up. It’s a kit (actually, a board) for a headphone amp. The difference resides s that it’s not made with what you have lying around, and its more costly.

I made an exception because I have a decent pair of Grados, which I love, and a I drive them with low quality audio mixer, which is OK for the price I paid. The thing is, to properly drive my headphones, I’d need something better, like the M³ headphone amp. Seems interesting. Let me know if you’ve heard anything good or bad about it.
