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?

The best? If you like tubes, then the best is a Cary 300sei (a lot of bucks!). Now, this is true for me; to my ears. Next best? Earmax Pro.

The Grace sounds fine but it is definitely solid state. The internal dac is not a very good one (sound-wise). The very high end HR Max stuff does sound very good (better than the grace) but also sounds solid state and costs way too much money. Just my two cents.
