Looking for thoughts/recommendations. I have for awhile now used an Ipod classic with a P51 as my portable rig. I have enjoyed this combination. I recently added a CypherLabs DAC with the new generation Ipod classic. The combination of the Ipod => DAC => P51 sounds great. However I am thinking maybe I can do better. The DAC is way bigger than the P51 so going bigger on the amp is not troubling. Based upon all the research I have done it seems that the Portaphile 627x or  AHA-120would currently qualify as the best portable amps out there. Being an RSA guy perhaps the SR71a, although not sure how much of an upgrade that would be to the P51.
 
Assuming cost is not a consideration is the Portaphile or the AHA-20 the best currently available? Should I consider something else? Thanks for your thoughts.
