Try whatever your heart desires, then a Synergistic Research AC Power Coupler. I'll bet it's the one you'll keep. Opens up the sound stage, great dynamics and solid, fast bass drive. With or without the active shielding, they are great PCs. You can try most through these guys, then keep the one you like: ( http://www.usedcable.com/cgi-bin/TheCableCompany.storefront/ ) Click on, "Power" then "Show All", and it's really easy to peruse everything they've got in stock. My second choice, in your price range, would be a Kimber PowerKord 10 Gold.
