Headphone amp for Sennheiser HD600


Any recommendations and where to get them? Are there any other choices besides Headroom?

I have a set of HD600 connected to a Headroom Max amp. It is a bit expensive, but it sounds fantastic to me. I use an Anthem CD1 as the source for this setup, it is what I listen to in the office.
In my most humble opinion there is only one amp for the Sennheiser HD 600 headphone, and that amp would be the Wheatfield HA-2 tube amp, I am a lover of that glowing bottle. Have been using one in my system for well over a year. One must sample this amp to truly understand what it can do to headphones. I will say there is no substitute for the main system, but, when the requirements are that my house be quiet, I do use it with great success and infact look forward to the session. The Headroom people are the sole sellling agent of this amp. Good luck.......
I got both the X-Cans & Creek SE amps from AA for a couple weeks. The X-Cans worked a little better w/ these cans. However, REPLACE STOCK TUBES ASAP W/ AMPEREX NOS and now it is no contest. Either Bugle Boys or A-Frames softened the Tizzy sound on some mainstream recordings while letting great extension come through. Incredible difference in the bass w/ the NOS tubes. Much deeper and tighter bass. These cans are very easily tweaked w/ interconnects too. I either use the Harm Tech Pro Silway MKII or Cardas Golden Hexlink 5C w/ them & again it takes it to another level.
Thanks to everyone for excellent advices. Although the Wheatfield is a nice amp, at over $10K, I think my wife would hang me before I finish listening to my first album. EarMax, MG Head, and X-Can v2 all seemed to be good contenders with MG and X-Can at roughly the same price.

I am leaning towards the X-Can as I have a huge collection of 6DJ8 NOS tubes available already.
I got it confused! I was thinking of the Sennheiser tube amp that I saw at HeadRoom's website for $12,000!
