This much has been covered before, but power conditioning does have its ups and downs...you can go too far with it and mess things up tonally and there is usually a wattage limitation and so on. But, I wound up going the "quantum" route (as originally started by Jack Bybee) and went with a company called Alan Maher Designs. They are not yet officially launched, but I fell into their facebook group in 2010 of about 300 or so members that are like early adopters...except a lot of what we buy from AMD amount to prototypes at not much over cost. Alan gets to develop new products and real-world test his gear with feedback folks from all over the globe and we get reduced prices...even if some of those products may be dropped from his lineup in favor of better/cheaper ones before he opens to the public. We are his 'guinea pigs'. Going quantum in this case means bypassing all the associated pitfalls with conditioning. I've been steadily buying his stuff since 2010 and have yet to encounter my first sonic negative or limitation. You can contact Alan directly with a fb message and he will respond quickly. He may or may not offer you a membership into the group. If not, then I'd say that it would be worth it to you to hold off on your decision until you can get access to some of his gear when he opens, whenever that is (you can ask him that, too). But, I suggest you start small..."fuse wraps" @ $15 each, "outlet pads" @ $20 each (fb pricing) (at your AV system duplex)...both of those things are dynamite and if they don't get you started for what can be done for that amount of money, nothing ever will...everything improves.
