Read the reviews of Shunyata conditioners and cords in Absolute Sound and Stereophile and consider their wide use among mastering professionals. Shunyata, Running Springs and Audience are widely considered to be the top three conditioner lines, depending upon tastes. If you have very serious power source problems, you might consider PS Audio's latest power re-generator.
I won't comment on specific power cords because they are so "component specific" and tastes vary so widely. However, I will say that claims that $50 boutique cords are as good as even Shunyata's $99 Venom 3 cord just don't stand up to a quick audition. ( see Neil Gader's survey of power cords) The folks at the Cable Company can send you a couple of things from the top two or three contenders and you can be the judge for the price of shipping.
