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...

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, the amplifier killer? Part 1 (updated Mar 2022)

Image
 Oh my, these Cobras can kill! I just typed 'Polk Cobra Speaker cables' in my google search (31/1/2021) and the got the following results in order of ranking. Arthur Salvatore's high-endaudio blog followed by two (eBay/hifishark) ads and the fourth result was "I hooked up the dreade d Polk Cobra Cables" (my emphasis). Forum comments on Polk Cobra cables are replete with phrases like "amplifier killer", "only suitable for Tube amplifier", "fries your SS amplifier", "be warned", "high capacitance" etc. I will try to debunk this myth that the high capacitance of these cables caused all those failures. I write this post with a foreboding that I am going to get flamed by some 'Polk Cobra experts' and past users. Well, bring it on, my Hifi-Brothers. Cobras did not kill my SS amplifiers, even six of them together! When I got my first 25ft pair of Monitor Audio Super Speaker cables (Polk Cobra, UK version), I was ...
