the overdrive is also a good headphone amp right?
what are some of the best headphones with the overdrive with no separate headphone amp?

I  highly recommend a tube headamp with ANY headphones.  I use a Bottlehead SEX1.2, which is currently on sale.  Its a kit.  Change the tubes to grey-plates and it sounds magnificient.  Never heard better.

I use Hi-Fi man HE-400's with it.  Beats Senns by a mile.
