1+ djones, Just changing the height of the speaker can make a significant change is sonic quality. You can actually measure this. If a floor is really bad decoupling the speaker physically from the floor will not stop it's resonation. Whether or not a move makes a system sound better or worse is a judgement call. You can certainly say it sounds different. This is particularly true in terms of bass.
Having a calibrated microphone and measurement program is very useful when it comes to setting up speakers. IMHO, thinking your ears are accurate measurement devices is a mistake.
