Thx for your impressions guys! I will take the sh440 (for rock and electronic music). However, due to the euro/dollar parity, I will also take a cheap headphone amp/dac. I am thinking about Asus Xonar Dx or HeadRoom Total AirHead or Nuforce icon mobile. Any advice?

Hi guys Is it better to buy a sh440 + cheap amp (NuForce Icon Mobile) or sh440 unamped (Realtek codec) or sh840 unamped (Realtek codec)?
