Hey there.
So, about a year ago I bought myself some Audio Technica ATH-M50's to use with my computer, so as not to keep others in my house awake (Night owl). I've also got some incredibly old computer speakers that I absolutely hate; they buzz, they cut out, and frankly I'm finished with them.
So, I'm on the lookout for new speakers, or a new set-up that would
1. Make use of my ATH-M50's
2. Include some decent speakers
3. Preferably have an easy to access jack for my headphones, as currently, I've got to go to the back of my computer, and switch the jacks for my speakers.
4. A subwoofer is not necesarry, as I'm living in my current situation for 2 more years and there is very little chance of it ever being used effectively.
So, I've got a budget of about 150$ and I'm unsure as to what route to go. I'm looking for them most bang for my buck so to speak, and I'm not sure about what would be the best for that: is it getting a stereo reciever and hooking everything up to that, or trying to get a sounds card and run eveything off that, or simply looking for some specific computer speakers with a head phone jack so as to save myself some trouble.
I think that, right now, my M-50's aren't being used to their full potential, as I've got no amp, or sound card.
Thanks for any information or suggestions you can give me.
My 1st idea is something like an Asus Xonar DG sound card and run cans off front panel of case and either amp + bookshelf speakers or active monitors off rear line out at the back of case 
Also i take it these are speakers that are right beside you when using the PC so they won't be more than say 2-3 feet away from your ears?
