How bad is the original power cable? The main problem with most cords is the cheap nickle plated brass plug with the injection molded plastic housing. As long as the power cord gauge is sufficient you might just try upgrading the plug.
You can easily spend $100 for just a plug but if you want to experiment with something cheaper check out the Sonarquest line. The housing is not as heavy duty as the pricier brands but the internal connections are tight and they use pure copper connectors (not brass). I used the red copper unplated connectors but for a little more you can also get silver or rhodium plated.
Just the plug for $12.50
