I built an O2 Headphone Amp

I’ve always enjoyed good quality sound, and I’ve also always heard that amping good headphones is a good practice.  My Sennheiser HD595 cans don’t need much amping at 50 ohms, but it’s been said on the interwebz that an amp can only help them sing to their full potential.  I figured, what the hell?

So I decided it was time to put my soldering iron (thanks for the wedding gift, mom!) to good use and get my EE skills back in action.  I was about to construct a headphone amp in an Altoids tin until my good friend Allen told me I just had to build an O2 amp.  I took his advice, and here it is!  (I’ll review it in a later post.)
