Change the balance only if you have some permanent problem. Like trying to balance non-balanced drivers. Sensitivity issues with one ear etc,. Stereo width could help you with soundstage, they can also be used just in case you need to put some life into otherwise dull recording. Compressors are like auto level correction modifiers. They are not recommended, unless you have lot of dynamics in your recording and you do not want them. Usually these could be with classical music, where at onestage you have very light passage and the next moment you have the choir/ensemble joining in. Usually recording engineers take an account for the compression. But its good to know that you have the options. Good recording companies like Chesky rarely use compressors in their track recording.
You could try eq only if you find that your headphones or earphones are not sounding the way you want your sound. They can also be used to eliminate hiss or other recording problems. Most modern songs do not need eqs, because of good recording technique and equipments. Few driver problems also could be corrected and many more.
Change your eq by abt 3 to 5 db at each step and then fine tune it.
Depending upon your selection your batteries will drain out (faster).
I think that Rockbox could void the warranty. My suggestion would be if you looking for warranty do not rockbox it. Once you are pretty certain that your player will not go bad, may be you could try them.
