basic steps to freeing a system
1) use 15 amp fuses not 20
2) loosen all the outlet plates in your audio room (plates that are on your audio system line)
3) loosen the screws on all components
4) take covers off the components
5) remove rubber feet from any component
6) use low mass IC and power cords
7) hard wire pass the AC connection on the back of components whenever posible

use as low of a gauge speaker cable as posible (I use 22 gauge)
9) loosen the screws where the RCA plugs are attached
10) take the barrels off of your RCA's
11) replace the cups on the back of your speakers when posible to a lighter weight one
12) place the speaker cables in without tightening them
13) loosen screws on drivers (just cracking them usually is enough)
14) remove heavy dampening products or drapes from the room
15) treat the upper corners of the room with barricade acoustical treatments
16) if you have a rack against the wall in front of you try pulling it out a little (usually in 8' tall rooms 16 to 18")
17) take grills off speakers
18) make sure speakers are not sitting on carpet
19) take out transformer locks when posible
20) remove any ties on any cables
21) try not to let cable touch each other inside the components
22) if your a tweak or have a technician remove your transformer away from circuit boards
I'll think of more but here's a start.
