Wish I had put more emphasis on cables earlier

My dealer, Audioconnection, sold me the AQ Thunders. He said if I didn't like them, I could send them back. 
Don't get me started on the William Tell speaker cables...

@OP,
I, too, was skeptical about power cords. I just bought inexpensive Zu cables and called it a day.
Then I listened to the new AQ cables-speaker, interconnect and power- and became a believer in what cables can do to a system.
Unfortunately, they can become costly.
Though it depends upon your equipment, and budget, I would recommend Audioquest Thunder power cords. They are the least expensive of the newest bunch released and will give you a taste of what a PC can do. They are popping up used nowadays, but I will say these cables are a bit unwieldy, so be sure to add additional length as well as some right angle connectors.
