I'm about to buy some Beyer Dt770 / 80 ohms and I am looking to build a cmoy amp. Are these amps suitable to drive the Beyer's with an mp3 player source (like a penguin amp, or any DIY amps you know of). I'm looking for a guide or plans for DIY cmoy amps also that would be good for headphones.

This is really a DIY forum question. There's a ton if information on cmoys if you just use the search function.
Anyways here's the defacto best guide:
