I agree with @guiffre
I haven't used a DAP ever but I've used the ES100 for a few months now with the CFA Lyra II, Andromeda, Sennheiser IE80S, and Westone W30 and I can't imagine anyone being disappointed in the quality of audio. I use it as a portable device of course and so I may not be listening as critically as I do when I'm at home with my HD800S and home setup but I think the ES100 brings my Andromeda's to near their full potential and that is wireless. It was also able to drive my HD800S and while not quite as well as it needs it was decent and more than loud enough for me.
I'm thinking of buying a pair of Andromeda's, and wondered about their characteristics/ sound signature when compared with the 800S. I'm new to IEMs, but I am familiar with the 650/ 800S both of which I use mostly with a Chord Poly/ Mojo. I bought an inexpensive pair of IEM's just to find out whether I could physically deal with the earpiece in, rather than over, my ears. I'm fine with that and I'm now ready to upgrade. I'm also interested in pairing the Andromeda's with the Earstudio (which I bought a couple of weeks ago) for more mobility/ convenience and keep the Mojo for more static locations like home or office. I would be interested in any thoughts you might have, or past experience that might be relevent.
