With warmer player like 801 sounds bloomy and veiled.
The best I have hear my ES10, with ESW11 pads, is with my Audiolab MDac, but that's not very portable!
@jhern I had an Iphone 5, it had the weediest amp I have ever heard, it cant drive any on ear I had. If you must use it then check out the Astell Kern AK10 or Beyer AP200.
