The first thing to do is to learn the most important tweak of all: Speaker Position. This is free and can make a very large difference in the sound of your system, more than an amp, preamp or cd player usually. Try different distances from sidewalls and the rear wall. Also try toeing in to the point of crossfiring in front of you a couple of feet. Find the best compromise.
Read up on room acoustics. This will affect the quality of the sound more than different electronics and can make a very large improvement in your sound. The cost per quality of sound unit is excellent.
Most of us here did it backwards in my opinion. We should have concentrated on knowing how to get the most out of our systems as they were before buying better gear. This will get you the best sound on the least amount of money. After thirty plus years in this hobby I feel that this is the most intelligent path and if I were to do it again I'd learn about room acoustics first, not after 20+ years.
