It is my belief and experience that most systems do not perform anywhere near potential because they have not been tweaked out properly. Resonance control, power conditioning, flux reduction, room acoustics, CD/DVD treatment, etc. These are the things that bring a system to life. This is the 'X Factor'. Upgrading to a new component can make a difference, but in most cases it will be modest to an already good system. Tweaks take time and experimentation, but typically are the most cost effective things that can be done to find the 'holy grail' as Raymonda calls it.
