Sorry, if you were an "audiophile" and you listened to some of the competition, you wouldn't have gotten an iPod. Don't pat yourself on the back too hard.
Have you tried another set of cans to see if they exhibit the same problems? If it turns out to be the headphones and the they are under $100 or so it's not worth fixing generally (unless your into DIY).
You for sure need to do some more research to make sure it's a good fit as a replacement driver. There's lot's of resouces out there with info on this. I did a quick search and found The Subwoofer DIY Page. But there's alot more to replacing a driver than matching the power handling and size...
I second the vote for an iAudio X5. Better SQ, more features, format support and cheaper than an equivalent iPod. iPods are way overpriced for what you get imo.
You can't just pop in another driver in an enclosure and have it sound good. There's alot of factors to consider. Trust me, you don't want to go there.
Well consider the iAudio 5XL that I have is rated up to 35 hours playback time it still destroys most DAPs in the market for battery life and then some.
And FYI a firmware update will provide ID3 browsing AND viewing by file structure very soon. But until then nope.
I'm a Grado fan, but I'd never use them for gaming. You do alot better with some closed Sennheiser or something like an Audio-Techinia A900. I agree with ya there.
I have a Colorvision Spyder Plus since I do alot a photo work and it's crucial that my output matches what I do on screen. It's a little pricey (approx $280 since it does printer color calibration as well). You can get a screen only basic hardware version for under 100 if you need TRUE color...
All laptop lockdown devices can be defeated super easy. Only ones that might help are the ones with alarms in case something is moved etc. alot like a car alarm.
If your college is that bad, maybe you should reconsider :)
