Do power conditioners really help?


I am a thinking about a purchasing a power conditioner for my system but really don't know much about power conditioners. I have a Denon AVR 5800 home THX with B&W Nautilus speaker set up. I'm also thinking about purchasing a power cable. I am currently using the Denon factory cable. If I buy a good power cable do I need a power conditioner? I'm clueless and wondering if I will hear any sound improvements. Prices I've looked at range from $30 to $2000. If I purchase, used or new, I only am willing to spend $300-$500. Comments welcome.

You can see the Richard Grey P.C. difference right on your
TV.It gets better with the more AC problems you might have
and don't even notice.Your 'blacks' will become really black
not some darker shade of grey.Skin tones look normal not
washed out.PC cords can make a diff but its not as easy to tell w/o a hi rez system. Video cables can make a Big and
easily seen diff, espec S and component cables.
