Well, No double you're going to get a variety of opinions about this subject. FWIW, here's mine, admittedly biased by my own experience. I'd suggest at least thinking strongly about buying a used PS Audio P300 power plant for around $500 and buying a couple of sub $250 power cords. The P300's are going for very little money now, good deals to be had on Audiogon. I can tell you the addition of a P300 was a revelatory experience in my system. The combination of a P300 and $500 worth of power cords is going to be likely to offer much more bang for the buck than $1k worth of cords. You could also read reviews of products from Shunyata, Audio Magic, Running Springs, BPT, etc. to see if you think their "house sound" night appeal more to you. Power conditioning is an absolute essential to me now in some form or fashion, it really does transform a system. Mike's suggestions are all good ones for cords. I can tell you I've had VERY good results for very little money by making up DIY cords from Cryo-Parts AC cable and Furutech IEC and male ends. For less than $150, you have a cable that brings a lot of sonic goodness to the party. Virtual Dynamics is having a half price sale for a short time. You can buy a new Power 3 for $152.00. I've got one of those and it's a no brainer for that price. A very good cable at that price. I've used that one on both my power amp and cd player to very good effect.
