ASL MG Head DT Head Phone Amplifier or Grado HPA-1

I am going to be getting a headphoe amp and headphones, the headphones will most likely be Grado Prestige 125 or 225's. Has anyone compare these headphone amps or have opinions about them. Auntique Sound Labs vs. Grado. I will use them in my main system and also run them with a portable. Thanks in advance!
The MG Head is a poor match with Grado's.

Best to stick with amps from Creek, Grado, or HeadRoom at this price point.
