Has anyone tried the Shunyata Diamondback PC?

I have the Diamondback. I don't think it is materially better than what you can get for $10 at Radio Shack. I also agree that the IEC connection is looser than it should be.

Although somewhat more expensive, the Audio Arts Power 1 and/or Black Sand Violet Z1 are both real upgrades. Audio Arts is good if you are looking for a bit of warmth, Black Sand is good if you are looking for great dynamics.

Wow. Kudos for such a gracious response. Shunyata will certainly remain on my short list for higher end power cords and power conditioners. But obviously your recommendation to work with a dealer and to "try before you buy" is good advice.

Sorry for the misunderstanding. I used the word "material" to mean "not imaginary", a valid definition, and to refer to the power cord's sound quality, not its physical attributes.

But since you claimed that I was just shooting my mouth off, let me be more specific about my experience with the Diamondback. I was short one power cord last year after adding a DAC to my system. To power the DAC, I decided to remove the Diamondback from my second system and replace it with an $10 power cord I purchased at Radio Shack. To my chagrin, the Radio Shack power cord sounded at least as good as the Diamondback. I can assure you I would have been happyier to learn that the Radio Shack power cord sounded inferior to the Diamondback. Nobody wants to learn he was a fool who has been separated from his money.

Now that I have clarified my statement, feel free to assure us that the Diamondback is more expensive to produce, better accredited, and safer than a Radio Shack power cord.

By the way, I am surprised to learn that the proprietor of Shunyata is going to the mat over an entry level product. I would have thought his time would be better spent on product development and manufacturing and that he would let the end results speak for themselves.
