What cable first


I currently have a B&K pre and B&K 200.2 amp with factory power cords. I also have an SVS powered sub with factory power cord. I'm considering upgrading in the power cords to something in the $100-$200 range per each peice, although one at a time. Which would make the biggest impact, if any? Also looking at ic's in the same range. I need to go from my Marantz cd player to my pre-amp. Maybe a power conditioner first would be better, and should my amp, sub and other components be on different outlets? If so, would I need multiple power conditioners? Any and all responses are appreciated, including witty sarcasm.

CD player or preamp first, then amp.
Have an idea of what type of sound you're looking for, even reasonable price cords can sound different from each other. The wrong cord will sound worse than stock cord.
When high-end companies started selling cords in the 90's, I thought it was a crazy idea, not until years later when I heard a cord sound good on a cd player, I was amazed.

Power cord is one of those things that some people can hear a day and night difference and some others can't. I personally can't hear any difference between various power cords that I tried over the years. So before you jump in buying, make sure you first borrow some and try them in your own system. It may save you a lot of money.
Thanks for your responses. They may have saved me some cash. What I might do is pick one up and swap it between components and see if I hear a difference. If not, look for it on here for sale! I've seen PS Audio and Virtual Dynamics used for $100 or so.

if it doesn"t make a change after 3 days ( cable comparisons are a joke since real cables need time to settle in),you will not have to spend any money on the subject.Hope this helps Dennis
