Shunyata Research Power Snake Diamondback Power Cord

I have never used that cord, since it was before I became involved with Shunyata. The Shunyata business model is to release new generations of power cords and power conditioners that exceed the previous generation performance at either the same price or lower. Contrast that with a certain three letter company that recently raised prices around 75% on their existing product line.

This review speaks highly of them.

"The Diamondbacks alone, and compared to my stock cables, offered more pronounced clarity and added detail, with a larger soundstage and slightly better imaging. When I played the CD of Andrew Manze and Richard Egarr performing the violin sonatas of Pandolfi [Harmonia Mundi USA 907241 1999], I could hear the bow against the strings of the violin as well as the sustain and decay of each harpsichord note. I wasn't just hearing sounds floating in space, but the actual instruments making music. I've had the pleasure of hearing Andrew Manze and Richard Egarr perform live and can attest to the excitement of hearing these spatial cues again. Before the Diamondbacks, I didn't know my system could transform this recording to sound so realistic."

I suppose you can quibille with the seller to save a few dollars, but IMO $100 seems reasonable.
