Crucial part changing, Soundcard

If you planning on better sound reproduction came out from your speaker, you need to change your sound source to a better one, in other words you should change your soundcard.
My onboard audio from gigabyte's motherboard was pretty decent for a common listener. But actually I think this motherboard missed some important factor when used for music listening. A bit lack in treble and bass made it sound a bit muddy in my Altec Lansing VS2121. It also produce a so-so bass that neither thumping nor tight. For a frequent music listener like me, who use winamp whenever I turn on my PC, that's pretty unsatisfying. Not that I hate the sound, but if you can improve the audio creation from your PC by changing your soundcard, then why not?
Hopefully, when I was searching for a good soundcard to replace my onboard one, my dad give his not-so-old "EDIROL" UA 25 to me. When I first saw this soundcard, I thought that this was a studio dedicated soundcard. But of course you can also used it as a standard soundcard too. EDIROL brand comes from the same company of renowned pro audio company, ROLAND. This thing was an external type soundcard, so you can plug your instrument in two input jacks ( if you intend to do some recording ), plug your speaker cable through the output jacks, and even adjusting volume level was all made easier. Oh and it support DIGITAL IN and OUT (coaxial) too. But this soundcard not supporting multichannel speakers, and it just have a RCA type connection. It's a recording dedicated soundcard afterall, and I don't really need a multichannel speakers cause I rarely watching movies or playing games in my PC.
Now comes to the sound quality. Well if I compared this to my onboard audio, it produce a noticeable difference. The treble was more crisp and clean thus it gives much more detail from my speakers. Bass and midrange was also sound cleaner and tighter. Though I thought that this soundcard was a bit too bright, but overall it improves the sound reproduction and it indeed better than my onboard audio.
