i want to ditch my midi hifi system in favour of getting a seperates amp and some speakers. i'm not looking for component advice just yet but my question is this - is it worth it because i have no interest in buying a cd player whatsoever. i intend to play all music from my pc in mp3 format (mostly a minimum of 200vbr). i intend to spend 300-400 notes on the speakers and amp. or am i wasting my time/money as i will be using compressed formats? guess i'll need a new soundcard as i'm still using a sb 4.1 card from years ago..... 
btw only interested in stereo for music, not surround or anything like that for movies.
