I just listened to Radiohead's Kid A over these without even breaking them in using my Native Instruments sound card. Boy was that a pleasure.
I used to have a crappy headphone amp I'd route out of an iPod Classic (using the iPod's DAC) to some Denon AH-D2000s. This sounded pretty bad (shrill highs that hurt my ears) and I sold the whole setup.
I want to try again with the ATH-M50's. They really, really sound good with the sound card I mentioned, but I'm not going to drag a DJ sound card with me to school.
I saw the portable Fiio cards on Amazon, but saw some pretty horrific reviews, and no customer support.
How bad are those products, really? I can't afford anything over $150 for this, is there any other products I can get for such a tight budget?
I did some googling for about 20 min, couldn't find anything cheap other than Fiio.
