hai. i need some advice from sifu here.

i'm looking to upgrade my speaker system and currently using AL VS4121 BLK.

for now i can say that Edifier S330/S330D is pretty much in the radar.

what my concern is, i really like my current speaker as i'm not really listening to loud-house-shaking music. rarely go more than 50% of its volume.

so i'm thinking that, changing to new speaker system may not make much different, isn't? how about buying usb sound card since im using laptop (realtek HD audio)? would it make any good?

im using my speaker mostly for movies>music. rarely gaming. my budget max rm7xx.

thx!
