I'll second Lak's comments,
Given the cost of investing in high-end conditioners, I'd make sure your AC lines are up to snuff first. The bonus of doing so is that you won't have to guess whether or not any power conditioners you try are actually causing a sonic inprovement, or just a different sonic flavor, since you'll know you have a solid AC 'foundation' to compare them to.
