I've been busy at work as of late, so I completely forgot to write my impressions. Before I start, I'm the kind of guy who can't hear a difference in cables and can barely hear difference between FLAC and MP3 for the majority of music (even though my collection is all FLAC). Well, here I go:
The little guy is convenient. The line-out at the back is good for hooking up a stereo system. The E10k can be connected to Android via. USB OTG, and it's very portable. The amp has plenty of power, but not too much (I keep it at about 3 on the volume dial). The bass boost is fun, but with this headphone, it can be overpowering.
It sounds good, but don't expect great ASIO on it. Even ASIO4ALL struggles with buffer sizes. I can't hear much of a difference anyway, so I don't mind much.
About the sound, I can't hear much difference compared to the Creative X-FI XtremeMusic, but it does tighten everything up a bit. I tried the Aune X1 MK2, and it had similar effect (but that is double the price and extremely powerful).
I do recommend this product for the X1, since it seems to pair well (and it has a nice and low output impedance).
