I am considering buying the V-Moda m100 headphones because I love bass and hip hop music. Along with that I would like to pick up a portable headphone amp. I know a lot of people recommend the Fiio e10k. I am fairly new when it comes to headphones and especially the amps. I use Audio Technica...

Thanks ill take a look into that

I was looking at that or the Fiio E07K Andes because it has great ratings, thank you for the suggestion

I have Audio Technica ATH-M50s, Sennheiser HD428s and Shure se215s which I use mainly through my iPod Touch 4th generation, do you think the Andes would be a good amp to use for them?

And I need something that isn't too large because I'm using them mostly on the bus because I have an onkyo TX-8225 receiver to use for my cans at home

I want to get a portable headphone amp that I can use with my iPod touch 4th generation and iPhone 5 as well as my laptop. Right now I have Shure se215 in earbuds, Audio Technica ATH-M50s and Sennheiser HD-428 headphones. I don't want to spend over $150. Some suggestions would be useful! Thank you!
