I used HD580 (same drivers) with Benchmark DAC1. More money but great sound. It can also serve as a preamp or portable unit for travel with laptop.
Sennheiser HD650 Headphone Amp
I have unexpectedly ended up with a HD650, and do not have a single component with a headphone jack, though it sounds surprisingly good direct into an ipod. I would like to find a headphone amp, under $200 used, or possibly an integrated amp or CD player with a good headphone jack. I liked it plugged into s friend's Decco but would prefer not to spend that much.

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. |
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. |
