Clear Sound with the Audiophile iPower by iFi Audio

iFi Audio iPower

Today, we get to present a new kind of power supply for all DAC and Digi Bundles. The iPower by iFi Audio is the audiophile power supply for Raspberry Pi sound systems. We got multiple requests from our community, to add a higher quality option for power supply to our Max2Play bundles. Now, after long consideration, we’ve decided on the iPower. Most Switch Mode Power Supplies can cause various interferences which find their way into the circuit of the Pi. The iPower by iFi Audio offers a solution for that problem. At the input as well as the ouput, it reduces floor noise to an absolute minimum.

According to iFi Audio, the iPower is ten times quieter than any other iFi adapter, twenty times quieter than audiophile linear power supplies and one thousand times quieter than usual wall plugs. At a comparative test of 7 power supplies and one battery, it has been confirmed that the iPower can compete with linear power supplies in completely different price ranges. It’s therefore the perfect SMPS for audiophile applications at the moment and an upgrade for most Pi-DAC and Pi-Digi setups.

What does the iPower have to offer?

  • Active Noise Cancellation+ (ANC) – to cancel all incoming noise

iFi explains: By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. With ANC+® the power line is filtered for audio band and RF noise. The measured noise floor of 1uV (0.000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of.

  • The 5V Version with 2,5A, suitable for all Raspberry Pi sound cards
  • Recommended for Raspberry Pi 2B und 3B
    Attention: Minimize power consumption with Raspberry Pi 3B + to guarantee full power with 2.5A.
  • Four changeable barrel tip adapters (UK/US/EU/AUS), USB and micro-USB to DC connector, as well as a right-angled extension cable
  • Easy and comfortable Installation

The iPower [by] iFi offers a cheap opportunity to give the sound its final touch.

iFi Audio’s iPower supplies are options that should appeal to anyone who suspects that a stock wall wart is less than optimal—as long as one is aware of the current required. The models I tried helped clean up the tangle of cables and supplies behind my rack, and performed well when used judiciously. Where the iPower’s low noise could help, it did; where it didn’t, there was reduced clutter with no harm to the sound. I intend to keep a suite of them on hand. Audio lab test result (translation from Mandarin):

The peak of the highest point [of noise floor] is not more than 1uV, the overall average of 150nV, measured data lower than iFi official data of 1uV, really low-key marketing. It can achieve this kind of performance with maximum loading, no wonder in the listening test it was much better than the LPS, my friends and I have heard. I later looked at the iFi’s official website, maybe this is the ANC+ technology at work, seems a very good “dark-art” technology, indeed should receive some praise.
