Deciphering Shunyata chronological history for upgrade paths


Shunyata cables have represented great technology and quality to me as I survey the marketplace. My first and subsequent purchases of the Diamondback & Venom level cables brought pleasing results to my system in staging, imaging and punch.
As I have read other A'goners experiments w/ "source level" power cords it intrigued me to do my own research. In considering a new or used cable purchase, the myriad of improvements and layers added to each manufacturer-or's product lines in this space, I was lost in names and misunderstanding of what has transpired in the Shunyata family of cables chronologically to make a good purchase decision.

Having good experience in calling Shunyata support to identify product distinctions in power purification, I reached out again and received a call from Richard R regarding my question of how to compare the new name sequences (hierarchy) versus the old. Richard was happy to comply and I am sharing this with the community in hopes to provide orientation for others like me deciding on upgrade paths.  Shared w/Richards blessing.

"Richard Rogers with Shunyata here:  Cables below are from least to best performance.

There's basically three eras the older snake named cables and the newer Greek named cables.
- Oldest: Venom ->Taipan -> Cobra -> Python ->Anaconda -> King cobra

- Then newer: Venom -> Viper -> Alpha ->Sigma

- Then newest:  Venom -> Delta -> Alpha ->Sigma

Now, through the time we had different designations and version of these. I broke those down below:

- Original series was just the snake named cable with no suffix

- Then came the Alpha Helix series (snakes) and VX series.
   The VX was for digital components whereas Helix was universal for all components

- Then came the CX series (snakes)

- Then came the Zitron series (snakes)

Then came the Greek series (Alpha digital, Alpha analog, Alpha HC, Sigma digital, Sigma analog and Sigma HC)

Now the current series is just the Venom 14, Venom HC, Delta NR, Alpha NR and Sigma NR. The NR version is a universal noise reducing cable that can be used on any and all components and the best we've ever built. "

"Davidhe19audio", I posed the question to Richard and here is his reply that  kind of addresses yours & "pops" questions...

" The Sidewinder was first a CX series cable that had a short production life due to its stiffness. Due to this stiffness, it was re-designed and became the Black Mamba CX.
We then had a Sidewinder VTX which proved to be more popular then the previous CX series Sidewinder and had a life span of about 3 years.
The Sidewinder models were both one level above the Venom HC and although designed for sources primarily, they will still function sufficiently on amplifiers or power conditioners like the Hydra 4."
BTW, just recently purchased a Python Alpha Cx 15a and initially it seems to have made a nice sonic improvement.

Although I have said the Venom/Diamondbacks were clearly evident compared to my "stock power cords", I will go back and do some A-B-ing as I also changed a source piece, so I want to hone in on the differences.

I'm debating between getting the Denali power conditioner or new power cords.  I even have a debate about which power cord to get. Is there a significant difference between Sigma and Alpha power cords? Does the Alpha offer more value for the money?

@ricred1 > I'm debating between getting the Denali power conditioner or new power cords. I even have a debate about which power cord to get. Is there a significant difference between Sigma and Alpha power cords? Does the Alpha offer more value for the money?

  I’d say look at some other PLCs that are contending as exceptionally well received and reviewed like possibly the CORT 1200 & 1800 models.

Power line conditioners are at times, great spots to affix a PC with noise reduction features. True that IF the noise reduction does not come at the expense of detail reduction or glazing over and leading edge performance dampning, which the VX versions were guilty of regularly. The helix versions seemed to better address actual ‘noise reduction’ without so much of the ‘VX’ ill effects.

RE Alpha value
It would sure seem from what Richard of Shunyata Res said to me, getting two Alphas would be the wisdom if only one Sigma could be swung financially, given the Sigs are twice the costs of a single Alpha.

With only four main entries on the latest SR PC lineup, the Alpha has to be some sort of mix between the performance of the former Taipan & Python cords, and the Sig more like the older Anaconda and or King cobra versions.

It was said the Sigma had a new tech in its build not previously instituted into any other model, ie., HARP.

It would sure be interesting to see the diffs from an Alpha and a Sigma on a source or amp. Just as exciting would be finding out if any for sure diffs were indeed to be realized between the NR versions and the non NR versions somewhere in the system.
