I have built the SDS Labs headphone amp using Int'l Rectifier IRF620 and IRF9620 with great success. IRF610 and 9610 could be a better pick but the '20 works like heaven in my amp. Mosfets available at digi-key.com.
I drive a pair of low impedance Grados with it and the amp is dead quiet on idle, have great dynamics and precison.
And yes, you should really put some resistance (I put 221 ohms) in series with the gate of each mosfet or the amp may oscillate.
If in trouble, post again!
