Thanks for the input guys.
I've narrowed down to AMP choice a bit, currently it stands between the Schiit Lyr and the Hifiman EF-5. Both Amps seems to work nicely with the HE-5LE.
How about DACs then? The ones I'm looking at now is:
HRT Music Streamer II
Schiit "?" - Supposed to be released soon
The Yulong 100 ones.
