Go to quieter and beyond, with the iPower2 Ultra-Quiet Power Supply, by iFi Audio.

Got underlying noise in your system? An irritating noise that you can’t explain? Sonics grainy? It could be as simple as your power supply. Upgrade to the iFi iPower2 to feed your system’s circuits with ultra-quiet, ultra-clean audiophile-grade power.

Simply use an iPower2 as a replacement for your regular power supply and get clean, noise pollution free power into your device.

The new iPower2 boasts improved components and a thicker gauge of wiring to deliver improved output/input noise suppression. And with Active Noise Cancellation II to cancel out all incoming EMI and RFI noise, you will never feel powerless against noise and graininess again. It is more than 10 times quieter than most audiophile power supplies.

Based on military tech, the improved Active Noise Cancellation II actively cancels all incoming noise. It does this in a similar way to active noise-cancelling headphones – it generates a signal identical to that of the incoming electrical noise but in the opposite phase, actively cancelling it out. This is highly effective at removing low- and mid-frequency noise, while passive insulating filters deal with higher frequency interference. This combination is measurably more effective at eradicating noise corrupting the USB signal than devices relying solely on passive filtering.

Available in 5V, 9V, 12V or 15V. Each voltage is individually available for your particular region and includes a reverse polarity adapter for centre pin negative products. Includes a set of 5 five differently-sized adapters to suit over 73% of DC plugs including a reverse polarity (white plug) for professional audio products that require a centre negative feed. Add the iPower2 into your system to bring life back to your music, and discover lost detail today.
