Best headphone amp for new Senn 650's


I just ordered a pair of the 650's with an upgraded cable from Drew at Moon Audio. I have been over at head-fi.org and Headroom Corp. and looked through these forums too and have come up with several possibilities for a new headphone amp. My question is, is there something that would considerably improve upon the Antique Sound Labs MG Head (older version with transformer, and Telefunkens) that I currently use with my Senn 600's? I am tempted by the Headroom new Max, the Grace 901, the Sugden Headmaster, and various other esoteric things I read about at head-fi. There are a lot of headphone listeners here, too. Any thoughts on whether I could substantially improve on the MG Head? Maybe other tubes than the Telefunkens I now use?

I am forced to chime in with my opinion on the Earmax Pro. I had a Headroom Max (SS amp) and the Earmax Pro is simply superior with HD650s--more liquid sound, less fatigue (crossfeed notwithstanding), amazing bass.

Be aware that the Earmax PRO is NOT the same as the Earmax--the Pro version can drive some of the more difficult headphones that the standard Earmax cannot drive effectively.
