I readily subscribe to Goinbroke's suggestions: optimise what you have, PARTICULARLY placement of spkrs in the room.
A contact enhancer is useful in helping "ohmic" contact BUT keep in mind that precious metals migrate so eventually the silver contained in the enhancer will migrate into your contacts. This may or may not introduce noise into the system. But it's cheap, even if you go for the branded stuff Jgiacalo recommends.
The ONLY thing that MAY make a marked difference in MUSIC playback with minimal outlay is the use of a good atteuator instead of yr pro. A transformer volume control for example could help and is not very expensive...
IMO, upgrading yr sources, yr speakers, etc will be very expensive; keep in mind that the spkrs-room combo usually introduces a lot more distortion than upstream electronics.
