Looking for portable headphone amps/dac under $100. I'll be using it with Sennheiser 558's & an iPhone 6. Would just like a little more punch when I'm on the go. 
 
Listening to a mix of ambient, indie, classic rock, jazz & classical.
 
I love the look of these little CMOY Headphone Amps. Are they any good?
 
Thanks!

It might be worth considering the Fiio E11k, it's a good choice at $59.99. It's shape is a little curved so you may have to level it out if stacking. It comes with a bass boost and gain but the volume control switch has no dampening so it's easy to turn accidentally. They're minor gripes, it's still worth considering.

Oh, forgot to ask. Are there any amps I can go out through lightning input/output as opposed to the headphone jack?

CMOYs sound pretty good. But I would rather have the E11K for the practicality of carrying around than the Altoids tin with a volume knob sticking out.

That would mean the unit has a DAC in it too since Lightning only does digital transmission, unlike the 30pin dock. You can get the Ibasso D-Zero MkII, that works with iOS7/iPhone5 and later versions. One problem is that you'll still need to use a camera connection kit.  If you're going to use it as a transportable though (mostly on a desk, but you can easily lug it around) then the D-Zero's a good choice, especially when you can manage cable clutter even with the CCK by putting the iPhone on a sync dock, as I do with my SGS3 and iPad2.
