EDIT: obviously not.
On topic, the Creative effects can make audio more fun, warm, bassy... whatever you want, but obviously move further and further away from the original quality. This is why "audiophiles" change source equipment oe headphones/speakers (as opposed to the file itself) because it can change the way audio sounds, but without actually changing the data (and potentially decreasing quality).
I do put everything to Default and the music just sounds dull to be honest. The high notes arent even there so they go up and i turn the X-FI Crystalizer to 'Max' and i notice a improvement straight away. But as i say, music is fine because im only interested in music playing out on 2 speakers (Entertainment Mode)
But for 5.1 Gaming Mode i want more...
