I'm looking for an amp, specifically to increase bass / bass punch on my sennhesier momentums. I need the amp to be able to work while charging. Budget is < 100 Eur.
I like to feel the cans vibrate my ears with a good bass kick.
 
I have a XiFi Titanium black soundcard at home. I can crank up the bass on it and when I try it with these headphones, so I know they have some potential.

However with my laptop / phone - I can't get some decent bass response. (Whatever EQ settings I use, turning up the bass via an EQ just results in very muddy sound).
Any suggestions? I've been tempted by the Fiio E11k and E6.
I'm using an HTC M8 btw, and a laptop with a pretty bad sound card at work.

For the most control/versatility get the Fiio E07K

E11k and E6 only have basic bass boost. (on or off)
E07K has 5 positive steps of bass boost and 5 negative steps. -10dB -> +10dB in 2bD steps.

But the E7k is also a DAC? Not sure if I need that...

but this is headfi, it's not about what you need

What about the JDSLabs CMOY?
