Thinking of buying a xmas gift for a friend to improve the sound quality of their laptop. Looking to keep this under $60, but when spend a few extra bucks if its worthwhile. My friend mostly just listens to music on a laptop and playing the occasional game with headphones. I have been searching the webs for solutions and I am seeing usb sound cards, dac, amps, and amp/dac combos as possibilities. Totally getting lost in all this, be great to get some recommendations as to what I should do. Thanks in advance.
