Cardas Clear speaker cables: Rev 1 vs older version


After upgrading my interconnects to Cardas Clear rev1 RCA, I’m looking to upgrade my speaker cables to Cardas Clear too. Buying new is over my budget unfortunately, so I have been checking out demo / used cables. I noticed some of the Clear speaker cables on the second-hand market (like my interconnects) are marked with rev1 and other are not. Is anyone familiar with the differences between the rev1 version and the older version? If so, can you please share your experience? Thanks in advance.

That's a great question and one that I do not know the answer to myself.  I would give Brian at Cardas a call and ask him- he is a straight shooter and not a bs artist, so you will get a real answer.
Thanks for your replies, I have sent Cardas an email. Calling is a bit difficult due to time zone differences.
