Also, if the above mentioned are a little to pricey, check out the excellent Wheatfield headphone amps.
I own an HA-1 (w/Senn. HD600's) and love it! All tube, PILLIOD transformer, built like a tank.
Around $530.
Here's a link to a review; http://www.northcoastweb.com/david/wheatfield/home.htm
can be purchased through "Headroom's" wb site (see under manufacture's list ander "H").
Good luck!
