Very exciting tech! Have you achieved the almost unthinkable, is the clean power so clean that you can't even measure those levels anymore?

Hi,
To answer your question, you may find itinteresting that that we have reached the 'measurment limit' of the Audio Precision - which is 1uV or 0.0000001V.
The Audio Precision that we use is a US$35k piece of equipment, not the cheaper one!
Rest assured, we are applying this technology across the board.
Hi,
ANC is totally unrelated to AIKIDO. We shall not comment on the details of AIKIDO here, but let's discuss ANC.
SPECTRA and Active Noise Cancellation technologies
No, we are not talking the upcoming Bond movie but the nomenclature is opportune!
Stealth technologies used in the military field fall under two main categories; passive and active.
https://en.wikipedia.org/wiki/Stealth_technology
- Passive stealth technologies are based upon deflection and adsorption of the incoming radar from the air defence on the ground. Hence less radar signal is being reflected back to the ground radar.
- Active stealth technologies are based on active cancellation technology. By sampling and analysing the incoming radar and feeding it back to the hostile radar on the ground defence out of phase, thus cancelling out the returning radar echo.
The French twin-engine, canard delta wing, multi-role fighter aircraft; Dassault Rafale, features an integrated defensive-aid system named SPECTRA, which among others, uses Active stealth technologies.

Active Noise Cancellation / Active Noise Cancellation +
iFi’s Active Noise Cancelling (ANC) and ANC+ systems are inspired by the Dassault Rafale fighter aircraft’s active stealth technology.
ANC/ANC+ detects the AC noise in the system and injects an equal, but opposite polarity noise into the system! The end result is that the AC noise in the system is all but cancelled out by this opposite noise signal. Just like this:
The difference between ANC and ANC+ is the ultimate level of residual noise physically achievable. ANC achieves a noise level that is already beyond most so call audiophile “super regulators.”
ANC+ has the lowest noise output currently feasible. It is at the limit of what the Audio Precision can detect.
To lower it even further, one would have to suspend the ANC+ circuit in liquid nitrogen!
