I don't know much about audio, but I've been using this software called FXSound for the past 20 years (called DFX Audio Enhancer back then). Simply having it install and turned on improved my audio. I guess it's just an equalizer app, but it makes a noticeable difference in quality. It used to be software where the free version was gimped (such as only being able to go up to 5 out of 10 on the levels like bass or treble), but now the whole product is completely free.
I've been using Cyber Acoustics 2.1 speakers for my PC for 15 years, and finally had my first set crap out on me last year (very loud static if I so much as sneeze on the cables for a while but I can't remember if it finally died completely or if I got tired of that problem). I upgraded to a newer model, and I'm having issues with it. Every now and then, the bass goes completely out for a couple mins. That first set was maybe $30 from Office Depot/Max though. Can't believe they lasted 15 damn years. I'm thinking about getting fancier speakers though. I'm not an audiophile, but I do like higher quality audio.
