iFi Audio iDSD GR 2 Portable DAC, Preamplifier, & Headphone Amplifier

A Legend, Perfected.
The iDSD GR 2 continues the story of one of our most celebrated portable designs - the xDSD Gryphon. Rebuilt from the ground up, it introduces a new DAC chipset and refined architecture, unlocking greater potential for sound quality than ever before. A new capacitive touchscreen interface and Nexis compatibility bring every setting directly to your fingertips, with no barriers between you and control.

From high-resolution digital inputs to advanced analogue connectivity and lossless Bluetooth, the GR 2 brings every element together in one uncompromising design.

It is our most versatile true-portable yet.

PCM1795. Pure Conversion Magic.
The GR 2 breaks new ground as our first DAC to feature the Burr-Brown PCM1795 chipset. It delivers the warm, analogue character we’re known for, but elevated with true 32-bit resolution, lower distortion, and greater dynamic range.

As a current-output DAC, it gives us complete freedom to engineer a bespoke analogue output stage - so we can extract the very best from the chipset.

Advanced Amplification.
With the change to a current-output DAC offering greater architectural freedom at the analogue stage, our engineers set to work on a new approach.

Class A op-amps offer a more natural analogue character, while refinement of the circuitry - now fully balanced from end to end - has considerably reduced distortion. iEMatch circuitry has also been upgraded with low-impedance MOSFETS.

The result is simple, but powerful - lower distortion, greater transparency, and more consistent performance over time.

Control, Evolved.
A new capacitive touchscreen OLED display brings direct, intuitive control to the surface of the GR 2.

This colour screen means core settings are now immediately accessible, removing the need for deep menu diving. The interface has been purposefully designed around speed and clarity, making device adjustments feel natural and responsive.

Restoring Musicality.
Digital recordings can often lose the warmth and natural richness of the original performance, leaving music feeling flat or clinical.

The GR 2 incorporates JVCKENWOOD’s K2HD Technology to restore depth, tone, and musicality - reintroducing subtle harmonic detail to bring recordings closer to their original intent.

The result is a more natural, engaging listening experience, with digital playback feeling less processed and more connected to the emotion of the performance.

For those who prefer a lighter touch, ‘K2’ mode offers similar enhancement without upsampling.

Power That Adapts.
The GR 2 introduces a new hybrid power mode that intelligently balances external power and battery operation. When connected to an external supply, it prioritises mains power first. If extra power is needed, GR 2 then draws from the battery, and automatically returns to external power once demand drops. That means you can leave GR 2 plugged in for longer listening sessions without constantly cycling the battery.

One GR 2. Any Setup.
Despite its compact footprint, the GR 2 is built to slot effortlessly into almost any listening chain. USB, Bluetooth, S/PDIF via coaxial and optical, and dedicated line inputs give you the flexibility to connect sources old and new. Headphone and line outputs extend that versatility even further, whether the GR 2 is driving headphones on the move or serving as the heart of a wider system.

Control Beyond the Device.
The GR 2 is fully compatible with iFi Nexis, extending control beyond the device itself. Through the app, advanced settings are easy to access and fine-tune, giving you a deeper level of personalisation without complicating the everyday experience. iFi Nexis also enables over-the-air updates, so the GR 2 can continue to evolve over time - adding refinements, features, and improvements long after it leaves the box.
