    Hi there,
    I think the fact that these infamous cables now have their own blog is wonderful. I have had one pair (the semi-oval unbranded type) for around 5 years and would never sell them. I have not yet heard a speaker cable which sounds clearer and more transparent to my ears. Following with interest!

Polk Cobra User comments & reviews Upated 11 October 2022

 This page is dedicated to user comments and reviews of Polk Cobra cables.  Those who have not used/listened to Polk Cobra cables please listen/try before commenting. Thank you. I will add some of the reviews and comments in the main post with permission by the author. I will leave all other comments in the comments section. Review by Sujesh Pavithran for Audiofi.net (Malaysia) This is an excerpt from a professional review of Accuphase E470 integrated amplifier.  Quote One final thing – I went through a variety of speaker cables, and a couple of weeks before I sat down to write this review, I managed to procure a pair of Japanese-made wires which, back in the 1980s, were marketed by Monitor Audio and Polk Audio (as Cobra) and have attain cult/mythical status. These took the performance of the E-470-1.7i to another level –  nuances were better revealed, there was an on-the-edge quality to the bass that will shock ribbon panel sceptics, and more clarity and r...

Polk Cobra Speaker Cable User Guide (Updated August 2021)

Introduction: These cables are rather special because of the design and manufacturing method that is unlikely to be replicated. ·          So called ‘Litz” speaker cables are easy to find. But unlike some so-called ‘Litz’ cables, Cobra is a true ‘Litz cable’ (not just Litz woven cable). The positive and negative strands are braided together without any Teflon (or similar) insulators. The individual strands are electrically isolated only by enamel (magnet wire or Litz wire). ·          The enameling process is world-class. There is no oxidation almost 40 years after manufacture! ·          A single run of Cobra contains 144 woven strands, 72 strands each for positive and negative! ·          The strands are made of extremely thin high purity copper. This seems contrary to what a speaker cable should be (more suitable f...

Re-engineering the Cobra (Thanks to Henry Fellner)

Here is a new post after a long break (been busy at work).  First of all, I would to thank reader Henry Fellner for starting me down this path with his post about removing the outer sheath, the inner damper and fluffing up the cable diameter (to remove dielectric materials and increase overall diameter). Although I agree with Henry's thinking (remove dielectric materials & increase cable diameter), I wanted to make it user friendly. Leaving the cables with no outer sheath (for protection) and no inner scaffolding (to maintain the shape and diameter) is hardly practical. Experiments: I removed the outer PVC sheath from my 1.5m single pair. Then I tested the following combinations. All original but without the outer PVC sheath. No audible change in sound. Removed the inner 4mm diameter Silicone damper and replaced with same diameter Teflon tube. No audible change in sound. Hmm...this was a surprise as I expected the removal of the solid silicone rubber damper to make a difference...
