Hi TBG, I have seen many discontinued Tara labs cables sold quite alot here on Audiogon, I have seen my model that is being sold currently by Tara Labs, The Zero Gold I/C sale at least 7 times on Audiogon in 3 years, but the speaker cables I have, The Omega Gold, not to be confused with cables that say omega only, I have only seen Omega Gold speaker cables on all sites in 5 years to be 3 times ever, their is a pair on audio asylum trading post for nearly $10,000.00 for a few years old used mint condition Omega Gold cables, But never have I seen on any sales site The Tara labs Zero Evolution I/C and matching Omega Evolution speaker cables, or Grandmaster Evolution cables, likly, one might not see that happen for a few years to come, also TBG, Not all Tara labs cables are the best, that is why Tara labs now makes cables that are 2 different classifications, called, controlled Band width and extended Bandwidth, Tara labs just started that in 2014 to better suite all systems synergy.
