Alpha Series in comparison to Zitron Python or Anaconda

Without question, I would look to the Alpha HC. It is the best value. They are measurably filtered and contain our most recent conductor technology. Second, I'd recommend any of the older CX Series power cords. Black Mamba HC for amps, CX for sources or Python/Anaconda CX. Hey, if you get a good price on a CX for Alpha HC, take it.

Your comment about reading an anecdote of radiation noise is a microcosm of what is wrong with posted internet opinion because anyone, even complete idiots, can post opinion. It's not your fault at all, we all read opinion and many time's its worth less than a penny.

Caelin has addressed this issue emphatically and in detail. Its a silly argument from one layman that wandered around with a tri-field meter thinking he knew something about measurement.

We beta things to death. We measure and re-measure. We spend a huge amount of resources just to vet the products. The power cords, power and signal products are brick-solid accurate and quiet. They do not communicate noise and we've done live and video measurements to validate that. A random guy wandering around with a tri-field meter was ridiculous and we addressed it.

Using shielding on power cords has limited value past entry level power cords because the shielding compresses the conductors to a small but audible degree. There are better ways to deal with radiated noise.. The EMI radiation is within an extremely narrow field, almost immeasurable in the way it affects surrounding cables or components, so the idea that it has some profound affect is simply not accurate to be kind. Proper cable-dressing is a far better way to address noise field energy. Crossing conductors or cables at 90-degrees, etc, not running everything in parallel with twist-ties, which I see ALL the time--would be a start.

I've stood in front of some of the smartest electrical engineers in the recording and medical fields and done demo's hundreds of times. There are no questions we are unwilling to address. Still, scant internet naysayers will have their way and it gets repeated.

Anyway, I appreciate the opportunity to reply and your sincere questions. I hope some of this is of some help.

Best regards,

Hi,

If it's me choosing and you already have Sigma in the system. I would hold out for an Alpha HC. It is truly a superior cable on any type of amplifier whether high or low current. Alpha Analogue power cords should be relegated to pre-amps and line level gear, maybe a DAC. The added money spent on an Alpha HC is worth it, in my experience. I would say the Alpha HC and Sigma Analogue are our Swiss Army knife power cords. They work with everything. However, if you have a pure digital output device like a NAS, hard-drive. video digital, then the the Venom Digital or Alpha Digital power cords are fine. Anything that has a dynamic-draw power supply, even a DAC? Alpha HC or Sigma Analogue if you can swing them, otherwise, Venom HC. I am a fan of bigger gauge for almost all non-digital-output components when it comes to our power cords.

I hope this is of some help. Feel free to write me at grant@shunyata.com with your system details. I would be glad to help.

Best regards,

Grant
