Desktop/Portable USB DAC/Preamp/Headphone Amplifier

A super-handy, heavy-duty portable audio device 

iFi Audio brought a "kitchen sink" mentality to the battery-powered, transportable micro iDSD Signature. This compact device as an external DAC, headphone amp, or even a preamp. It sports a tough metal frame and can be used in a desktop setting or on-the-go. 

When connected to your phone or laptop via USB, this space-blue beauty overrides the ugly audio circuitry within your device. iFi's top-notch audio technology takes over. The built-in headphone amp ensures your headphones have enough power to perform their best. The micro iDSD also doubles as a stereo preamplifier, with inputs for handling your digital music sources, plus RCA outputs for connecting directly to an amplifier.

Customize your sound

You get several controls for tweaking the sound and functionality. iFi "crowd-designed" the R&D, and asked the most hardcore music and headphone aficionados what they wanted from a DAC/headphone amp. The result is a collection of buttons and switches that give you control over gain, digital filtering, bass, sound dimensionality and more. The back panel features digital inputs and RCA outputs for using the micro iDSD as a preamp.

Dual high-performance DAC chips

The micro iDSD uses two Burr-Brown DAC chips, each dedicated to a single channel to avoid noise or crosstalk. These high-grade DACs can squeeze out more musical detail from Spotify®, Apple Music®, YouTube®, and other digital audio sources. They will decode high-res PCM music files up to 32-bit/768Hz resolution,as well as single-bit DSD files up to 24.576 MHz (DSD 512). The micro iDSD also offers full MQA support.

Headphone amp with balanced and unbalanced outputs

On the front panel, there is a 1/4" stereo headphone jack along with a balanced 4.4mm headphone output. The latter is the new industry standard balanced connection that helps cuts down on signal noise and distortion. A growing list of headphones from multiple brands use it.

You can select from three different power modes to deliver the proper amount of power for your headphones. In "Turbo" mode, this amp can deliver up to 4,000mW to drive power-hungry, high-impedance headphones.

Power match for high-performance earbuds and IEMs

On the other end of the spectrum, you can use the iEMatch control to optimize the amp for highly sensitive headphones, like in-ear monitors (IEMs). iFi's proprietary iEMatch technology lets you adjust the power output while still preserving the sound signature of your 'phones.
