yes, the AD8397 worked as OP and BUF in E11, but only worked as BUF in E11K, that is what we try to make the sound better. so you will still have the advantage of the huge current output of AD8397 but OPA1642 will decide the sound color.

Holy powerful! FiiO, you seem to have outdone yourself based on those specs! Is the clipping problem I had with bass boost on going into 32 ohms above 5.5/8 volume fixed too?

This amp looks lush.

I've been toying with the idea of getting a portable amp for quite a while now. My iphone 5 does seem to cut it in terms of driving my m50x's. I was keeping my eye on the E06 but I'd love something with a bit more umph

But it sucks that it only has 1 bassboost and it's not as good as the older E11 right.....?

I'm on a budget so it seemed like the best one for me. Although I would be prepared to dash out on something which looks as nice as this. Also, I'm not in it for the bass, I want something which can actually gives my headphones enough juice to play songs at high volume.

What is the actual output impedance of the E11K?

lol! M50X do not need an amp. A phone with half as much power as an iPhone 5 could power it completely. Save up, and buy a decent open back headphone and an amp. Portable closed back cans dont normally need amps... The only reason you should buy an amp with the M50X is if the iPhone isn't loud enough at full volume... Do you listen at full volume and want more volume than the phone has? EDIT: Read your other post... I suggest not listening at that loud of a volume for more than 20 minutes. You will damage your hearing.

That's exactly why I want a portable amp. Also I do find that bassier tracks seem to distort slightly at the higher volumes, whereas on my hi-fi amp they do not (ruling out a source or a headphone problem).

well at least turn down the treble lol. The higher frequencies will damage your ears. I'm ok with bassheads... I am an audiophile/extreme basshead myself... I just don't like when people play music that loud, and don't turn down treble. Damages ears. Have you considered an open back can? I don't like the m50x's... About as much detail as a beats by Dre studio 2.0. (they are actually pretty good.) or a v-moda m100. All three strictly portables.

Yeah, I totally agree with you, ruins the music in all honesty. I'm really savvy when I comes to changing EQ on the higher volumes. I do think there is a problem with my iphone as it does seem to play a little on the quiet side.

Do you know if there are any portable amps which run directly out of the lightning connector on the iphone? That would be very interesting for those of us who dislike the sound produced by the cirrus chip and aid in the powering of a portable amp.

  so its better in this department , still 1.3 ohm on the 11k is not bad , and the 16hrs battery is good !! i will wait for the price .
