iFi Audio DC iPurifier2 Audiophile DC Power Filter

Drastically reduce the noise and improve the performance of your DAC, streamer, laptop, set-top box, guitar effects pedal – basically, every and any DC-powered device – with the iFi DC iPurifier2 power conditioner. Able to vastly enhance the sound, clarity, and operation of the Switch Mode Power Supply (SMPS) in DC products, DC iPurifier2 uses Panasonic SP-cap polymer capacitors and military-grade Active Noise Cancellation2 technology to reduce noise by a factor of 316x up to 100,000x – or, a noise-floor drop of 50db to 100db! You'll hear deeper-seated details, striking inner resolution, blacker backgrounds, and smoother tones from all your sources. The buzz, noise, hiss, and jitter caused by the power supply will be greatly reduced. All you need to do is insert DC iPurifier2 between your existing noisy power supply and the audio source.

Effective from 1Hz all the way up to 5GHz, and offering extreme enhancements from 20Hz to 20KHz, the ultra-wide-band DC iPurifier2 is compatible with all power-supply designs (5V-24V/3.5A/84W). Three included adapters/pigtails accommodate for different-sized DC barrel connectors and ensure that no matter what type DC device you want to connect, it will work with DC iPurifier2. Built-in polarity protection, copper-alloy shielding that blocks EMI, and custom operational amps all come built into the device. With DC iPurifier2, you'll know why silence never sounded so good. 

Have a Noisy Generic Switch Mode Power Supply? Just Add DC iPurifier2
Generic Switch Mode Power Supply (SWPS) designs are noisy because they were only intended for mainstream. Hence, noise was never a consideration. Now, such distraction is no longer a problem. Simply insert DC iPurifier2 between the existing noisy power supply and the source and enjoy noise reduced by a factor of 316x to 100,000x (or by 50dB to 100dB, respectively). Be it home or professional audio, this is the most simple and most effective way of improving audio performance from one of the most noisy sources in a computer audio system.

Compatibility with All Power Supplies, Ships with Three Adapters
DC iPurifier2 handles 5 volts through to 24V and takes up to 3.5 Amps or 84 watts. For different types of DC barrel connectors, DC iPurifier2 works with 5.5 x 2.1mm but also ships with adapters for 5.5×2.5mm and 3.5×1.35mm. These three fittings cover the gamut of DC barrel connectors and ensure compatibility with all power supplies.
