Both caps and resistors will likely increase resolution and lower perceived noise floor. Retaining the tonal balance with these upgrades is a delicate balancing act. Most caps I've dealt with increase brightness to some degree, usually this can be adjusted for elsewhere in the system.
Modding power supplies may be helpful as well, particularly with the transients. I'm upgrading my Cayin's phono pre bridge rectifiers with HEXFRED's and bypassing the electrolytic caps with film caps next week, should have some answers soon. I'm looking for increased transient behavior, specifically more slam.
If you do go the modding route, just remember you can always undo the changes. I've also found modding to be the most interesting aspect of this hobby, really amazing sonic upgrades here! Endlessly replacing components is way too costly and relatively boring.
Mods are the way to go if you have some guts and soldering skills! Practice on cheaper pieces, gradually working your way up to more expensive components.
