Is there anyone here who uses the HD-400 with the Fiio X3? Does the amp do justice to the headphones? The X3 did a lot for my HD558 and M50, but worried about the hard-to-drive tag that the orthos have built up. Would love to hear from people who've already heard the combo. Thanks!
The HE400 is one of the easiest to drive orthos. I've tried the X3 with even the Alpha Dog and the sound was very good - sure they can scale higher but the HE400 should still sound both loud enough and pretty impressive with the X3.
