For what it is worth, most audiophiles will tell you that changing out the weakest link will make the biggest difference on overall sound. Thus, if your amp is the weak link, changing it out will make the most difference. If it is the preamp that is the weak link, swapping the preamp will make the most difference.
The post that said that 95% of the sound is room, speakers and source material is embellishing somewhat... but not that far off. I'd say it is 70% and that ones CD player is 15% and amp/preamp is about 10% and interconnects/cables are 5%.
