Best power cords in the $250-$400 range?


I am still running stock factory cords and am looking to upgrade.
My system:
Speakers: Proac Studio 200,Proac CC2,Definitive BPZ/A in-walls
Sub: Sunfire Architectural Signature
Front End CD: Denon 2910 Processor: Rotel 1066
Amp: Rotel 1095
Power Center: Monster 3600

What would you recommend for me getting started to hear the biggest positive impact for my DVD and Pre-amp? For my Amp? Should I put more $$ into any one cord? Should I upgrade my CD/DVD and spend less on cords? Hope this will start a good discussion.

Front-end > preamp > amp is the order in which you prioritize your power cords. I've always liked David Blair's CCPC cords, especially the "Top Gun".

And get rid of the Monster 360, and replace it with one of his "Power Blocks"
Black Sand Silver Max.

I am auditioning this right now and it is pretty much on par with my reference (VH Audio AirSine). Most pc's I have tried can't make that claim!
