First off it is an addiction with no cure, patch or silver bullet and none of us would change that!!!

The only way to temporarily stop the craving monster inside is to obtain the latest and greatest sounding gee wiz gadget available at that very moment!!!

Your system looks tight, what source components are you running? To improve sound, I would experiment with speaker placement and, if you do not already have one, look into a power conditioner to maximize your systems overall sound and especially video performance. Otherwise your system sounds killer!!!
