iFi audio SilentPower iPower2 5V Power Supply Adapter

SilentPower iPower2 5V — Ultra-Low-Noise DC Power Supply

This plug-in upgrade replaces noisy stock wall-wart adapters on any 5V DC device suffering from hiss or hum. Active Noise Cancellation II injects an opposite-phase signal to cancel incoming electrical noise at the source, dropping the noise floor to roughly 1µV. With a 5V/2.5A output, USB-C and USB-micro pigtails, plus five interchangeable DC barrel tips including a reverse-polarity white plug, the unit covers around 73% of common audio gear.

Why upgrade your stock power supply

Most bundled wall adapters leak EMI and RFI noise straight into sensitive DACs, streamers, and phono stages. The iPower2 5V feeds those circuits with cleaner, more stable DC so the rest of the signal chain can do its job without fighting contamination from the mains, all from a compact 82 x 43 x 43mm, 165g housing.
