iFi Audio iPower Plus for Pro iCAN & Pro iDSD (15V)

The central characteristic of iFi is in pursuit of the zenith in audio performance: it leaves no stone unturned. Well, the all new iPOWER is an exemplary example of this. Despite the fact that the iFi Ultra-Low Noise AC/DC adapter was exceptionally quiet and elevated the iUSB and iPhono to punch way beyond their respective categories, the all new iPower is even quieter, up to 10x quieter in fact.

Aimed at the iFi Audio Pro iCAN and Pro iDSD, the iPower Plus offers all of the benefits of the iPower however at a higher output rating of 15V/4A with removable IEC power lead to accomodate for different regional connections and lengths.

Three years ago, iFi’s Ultra-Low Noise AC/DC power adapter set the way and underpinned the whole iFi range from the iUSB to the iPhono leading to their loyal following. Well, not to rest on its laurels, iFi now has a completely new ‘ground-up’ DC powered supply.

Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation+ (ANC+) audio power system. It is so good ANC technology is now a cornerstone of the ever-improving iFi USB audio technology range. An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an onboard system to cancel out the enemy radar signal. By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+® is the perfect ‘antidote’ for power supply noise, the bane of USB audio. With ANC+ the power line is filtered for audio band and RF noise. The measured noise floor of 0.1uV (0.0000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of.

Measured on the Audio Precision 2, the iPower has an astonishingly low audio band noise floor of just 1uV! To put this into context, iFi’s very own Ultra-Low Noise AC/DC adapter was in a class of its own at 10uV. Compared to a typical audiophile Linear Power Supply which measured at 20uV, it is demonstrably clear AMR/iFi power supply technology is unparalleled.

Shaping the face of technology, AMR/iFi not only pushes the boundaries of audio design, but power design too. After all, electricity is the “fuel” behind the audio signal. The 12-Element Output Array dynamically suppresses noise in real-time as it makes its way through the mains. Technology like this is quite simply unheard of in audio power design.
