I currently have an Acoustic Zen Tsunami in my system. It is the least expensive cord presently in my system. It is the original model, which had an inexpensive Hubbell male plug on it. I found its performance to go up quite substantially by upgrading the plug to a Wattgate 330i. This simple change of male plug takes most, if not all, the quibbles away which other owners have talked about. And just importantly, the duplex outlet is a Porterport, a perfect match for the plug. Tsunami AZ offers a UPOCC plug for $25.00, but the owner, Robert, strongly urges you to send them your cord for them to install the plug. He offered to install at no charge, but you're still out shipping both ways. The new Kaplan cord is one I've got on my wish-list for future evaluation. By the way, I've not tried the Audience and AP power cords, but I did have both of their top line speaker cables in my system and the AZ Satori beat them both out, imho.
