Power supply iFi Audio - iPower Elite, 15V, 3.5A, gray

The iPower Elite from iFi Audio is a low-noise external upgrade power supply. It works with virtually any DC-powered device, providing silent, clean, better than audiophile power.

The Power Elite by ifi Audio is designed to deliver smooth, quiet power. It gives your streamer/DAC/amplifier all the quiet, clean power of a battery without any of the hassle. Based on military-grade technology, the enhanced Active Noise Cancellation II actively cancels out all incoming noise. It does this in a similar way to active noise-canceling headphones; generating a signal identical to that of the incoming electrical noise, but in opposite phase, actively eliminating it. This is very effective at removing low- and mid-frequency noise, while the passive isolation filters handle higher-frequency interference. This combination is measurably more effective at removing noise that corrupts the USB signal than devices that rely solely on passive filtering.
