I have the ATH-M50 and I don't think amping would help much. ( have the Pico Slim/E-17 and the ELE-Dac ). I'm not sure if I have the right amp though but since your deployed, check your Base Xchange for Vmoda M80. I just scored one for $119 in Kandahar. They still have few left when i bought mine.
Cheers!.. be safe..
