See if you can find a used Little Dot tube headphone amp.
I have one and it works great with my HD580's.

Sennheiser HD650 Headphone Amp
Bottlehead Crack OTL headphone amp is $219 new. It was designed for high impedance cans like Sennheiser HD650. You'll find plenty of technical info and owner comments in the Bottlehead forum. |
I use the HD600 hooked to a Firestone Audio "Cute Series" amp with a matching power supply. Inexpensive and works well. I was unable to drive the 600 with the headphone output of a Mcintosh pream or with an E-Mu USB interface. The 600 needs a little more drive than say a Grado 60, but not a ton. The Firestone amp works fine. |
