Until you get the official answer, this helps explain the Alpha.
Shunyata Research: Products: Signal Cables: Zitron Alpha Digital
My understanding is the digital device generates the noise and it reflects back onto the power line. From there it affects other components. The Alpha filters this reflected noise, which removes it from the power input to other components. Take that with a grain of salt, so to speak.

Mine is amazing. It actually makes my digital sound good - really good!
The landscape of high-end audio is shifting toward more digital source materials and to a corresponding preponderance of equipment to playback and process digital audio. We are seeing more media servers and computer based audio systems. Components with CPUs and DSPs and other digital circuitry tend to produce significant amounts of very high frequency noise that is passed through the power supply onto the power line and is radiated as EMI.
Personally, I have been working with a variety of media servers and hi-rez files as many of you have. While the source material is superior, the addition of the media servers (computers, drives, monitors) added significantly to the noise and RFI on the power line. For me, this made the system virtually unlistenable compared to a system using a turntable or a good CDP. We looked for a solution that could isolate these component's EMI and switching noise. There are and have been power cables designed to reduce RFI but these invariably use ferrous materials (ferrite beads and carbon coatings) that reduce DTCD producing a compression of sonic dynamics.
Our research in the past several years has been focused upon power supply noise and how best to intercept and sink it. Some of our recently released products are the result of that research. Products like the VENOM DEFENDER and the new ALPHA DIGITAL PC cable deal with noise specifically and locally as opposed to generally in a large power conditioner. Digital components operate in the Megahertz and Gigahertz frequency ranges. The digital PC intercepts noise from the power supply of the digital component, preventing it from contaminating the power circuit. Noise and EMI are most effectively reduced when addressed at the source. The cable has a significant performance effect even if you already have a first rate power conditioner.
We are continuing along this design philosophy and there may be other application specific products announced in the future.

Thanks. I'm glad you mentioned the Defender. I have my Classe' CA M600's plugged into 2, 20 amp dedicated circuits. I have no room for a conventional power conditioner , so I was wondering what kind of benefits the Defenders will give me. BTW, I've already ordered them.

Interesting. I have been half-way wondering why my Triton didn't handle this noise. Seems like a nice addition to the next generation of power conditioners.

Welcome to AS Caelin.
The Alpha Digital PC from the Triton to the Esoteric K-01 player has really worked wonders for my system.
It does everything as described. Thanks, Caelin, for an excellent product.
