Hi there, this is my first post here. I'm quite new to the world of audiophiles so please excuse any ignorance I may show in my questions.
I own a pair of V-Moda M-100's and also a pair of Audio-Technica ATH-IM70's. I use the IM70's mainly for their ease of portability. I am hoping to get a portable headphone amp and have been looking at the Fiio E07K portable headphone amp. It's within my price range and has had some very decent reviews. When I'm out, I mainly listen to music on my smartphone (Samsung S3). If at home then I use my computer.
My question is, do I really need the portable headphone amp for the IM70's? From what I've read on these forums, I think my M-100's may benefit from the E07K. However, what I'm concerned with is that the specs of the E07K list the headphone impedance range as being 16 Ohms - 100 Ohms, where as the IM70's have an impedance of 10 Ohms. Will using the E07K with these IEM's damage them in any way? Will it even make a difference in audio quality if they can be used?
Also the IM70's have a listed maximum input power of 200mW. The E07K has a listed output power of > 220 mW@32Ω /> 250 mW@16Ω.Will this also be an issue if I use them together?
Thanks in advance for any replies XD
