The following are free, and are probably the most important things you can ever do.
- check the set-up of your speakers, and correct it if they are off even by a little bit
- try putting some natural room treatments at the obvious spots and see if it helps with either diffusion or absorption
- clean your contacts, all of them
These others are relatively cheap.
- have an alcoholic beverage of your choice, in moderation
- do something to improve the power delivery to your components, be it a conditioner or replacing stock power cords
