I've built a couple of these and they sound quite good.

Also, member rjm(Richard Murdey) offers a kit for his Sapphire headphone amplifier that's pretty popular.

I read something about that... what other choice's do I have to go along with the 15 volt trafo?
gonna use DT770 250ohm on it.
Even if an amp has a low offset it would still be prudent to use a pair of coupling caps on the output, or better still, a transformer. You don't want to lose your expensive cans from a failure of a relatively cheap headamp.
