Which Headphone Amp for Sennheiser 600?

I want to buy a used headphone amp to drive the 600, any suggestions?

I have a Wheatfield HA-2 for sale with a wide variety of upgrade tubes available. It's the top of the line tube amp that Headroom sells. Plenty of power for the HD600s (which I use too) and an extremely dynamic amp. If interested, contact me.
