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 bought a pair of HD 600's with my Benchmark DAC-1 and am very happy with it. The benefits obviously being that for the 850.00 you get a very high quality DAC.

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.

shows a Larocco amplifier which was designed to use with HD 650s. It's off PPA design.

Ive used my rkv with my hd600s for four years now, sounds fantastic but I cant compare to anything else as I havent heard any other amps. Ive never felt on the other hand that anything was wrong so never thought about upgrading. Its worked wihout fault for four years but I think I should look for some new tubes for a possible upgrade.

I bought an RKV secondhand a few months ago, no problems to date. Remarkably immune to tuberolling. Seems like a sturdy piece of equipment to me.
