The Shunyata web site has a discussion of the underlying technologies used in the new Anaconda and Python signal cables at:
I have the new Python interconnects and speaker cables. I was very skeptical as well. They are more transformative in my system than any single Shunyata Power cord and I own the Anaconda CX's. I hear increased transparency, detail, bass, better PRat, etc. I've never heard cables do anything like what they do. That's just my experience. People owe it to themselves to audition them.
It's always a good idea to take advantage of discounts on older lines when Shunyata releases an upgrade. I never auditioned their previous wire.
I *will* say this: the Pythons utterly destroyed my previous reference cables, which cost $2K for an 8-foot pair. I'd say it was like going from zip wire to my reference, but that wouldn't be true. It was more like going from a low end cartridge to a top-of-the-line Dynavector. It's too bad they couldn't come up with a way to disguise these cables in a big metal box because it's hard to believe mere IC's and speaker cables can yield the results I'm hearing.
I am also interested in any comparisons between the new Shunyata interconnects and earlier generation such as Aurora and Stratos.
Nothing I have tried so far is as musically satisfying in my system as Teo liquid STD mkII interconnect.
I am considering comparing Shunyata(old or new) to my Teo so would be interested to hear others thoughts on them.
According to Shunyata, even the the new Black Mamaba IC's are a major step up from the Aurora and Stratos...at a fraction of the cost. The Absolute Sound will be reviewing the Anacondas in the February edition. Galen Carol Audio, the Cable Company and Music Direct all have loaner/return policies that only involve shipping costs (usually $30). The buzz (and i concur) is that these wires are game changers. Only your ears will know for sure. Hope you get a chance to audition them.
