The iFi iDSD GR 2 is a reference-grade transportable DAC and headphone amplifier engineered to deliver uncompromised desktop-class power and audiophile fidelity in a mobile form factor. Featuring iFi Audio’s custom quad-core Burr-Brown DAC engine, ultra-high output power, precision GMT femto-clocking, and built-in IEMatch technology, it provides effortless drive and absolute acoustic transparency for both delicate IEMs and demanding full-sized planar headphones.
Key Features & Innovations
Quad-core Burr-Brown DAC architecture — the iFi iDSD GR 2 features four interleaved Burr-Brown DAC chips working in a custom interleaved configuration to deliver exceptionally low noise floors and bit-perfect playback up to PCM 768kHz and DSD512.
Massive desktop-class power output — provides substantial drive power with selectable Turbo, Eco, and Normal power modes to effortlessly power high-impedance headphones and power-hungry planar magnetic drivers.
Integrated IEMatch & Active Noise Cancellation II — built-in IEMatch attenuation cleanses background hiss for sensitive in-ear monitors, while ANC II cleanses incoming USB power for dark, silent acoustic backgrounds.
XBass+ & XSpace analogue tuning — features hardware-based analogue signal processing to expand soundstage width and restore deep low-frequency punch entirely without digital DSP manipulation.
Versatile digital & analogue suite — includes ultra-low noise USB-C, S/PDIF optical/coaxial digital inputs, balanced 4.4mm line out, and front-panel 4.4mm balanced and 3.5mm S-Balanced headphone jacks.
FAQ — iDSD GR 2
Does the iFi iDSD GR 2 have an internal battery?
Yes. The iDSD GR 2 features an internal high-capacity rechargeable battery that provides clean DC power to the audio circuits, isolating the DAC from dirty host USB power while enabling portable use.
Can I use the iDSD GR 2 as a desktop DAC for my home hifi system?
Yes. With its rear balanced 4.4mm line output and optical/coaxial digital inputs, it integrates seamlessly into desktop speaker setups, integrated amplifiers, or preamplifiers.
What is IEMatch and how does it help with sensitive in-ear monitors?
IEMatch is a built-in attenuator circuit that reduces background amplifier hiss, lowers gain, and matches output impedance specifically for ultra-sensitive IEMs without compressing dynamic range.
Does it support full MQA hardware decoding?
Yes. Powered by an advanced 16-core XMOS microcontroller, the iDSD GR 2 performs full hardware MQA decoding up to 384kHz alongside PCM 768kHz and native DSD512.
