A well sorted $12,000 system is not "rubbish" compared to a similarly well sorted $25,000 system, but the difference should be absolutely staggering (or night/day). One might have a different opinion on whether the money was worth it, but the leap in sound quality will be profound. As opposed to better fuel, this would be analogous to adding a turbo-charger, larger brakes and better exhaust system. I almost feel badly for those who are lost on this. It must mean only one thing- they've never experienced anything more than nuanced upgrades. While those are nice, the big leaps now and again are absolutely real and absolutely necessary in order to continue down the path toward an ultimate experience. It will be interesting to get kevintomb's view of my system once the upgrades are completed.
