iFi Audio iDSD GR 2

The iDSD GR 2 marks a generational leap forward as the successor to the legendary xDSD Gryphon, re-engineered to redefine portable audio. At its heart lies a premium Burr-Brown current-output DAC, introducing true 32-bit resolution that preserves iFi's signature warm analogue character while expanding dynamic range. Wrapped in a sleek chassis with a vivid colour OLED touchscreen, this powerhouse effortlessly bridges the gap between desktop performance and on-the-go convenience.

This current-output architecture allows for a bespoke, fully balanced analogue output stage built from the ground up. Utilizing custom Class A op-amps for a natural tonal signature, the GR 2 unleashes an astonishing 1,513mW of RMS power - a 50% increase in headphone drive over its predecessor. Paired with an upgraded MOSFET-driven iEMatch circuit, it easily commands demanding planar headphones while remaining dead-silent with sensitive in-ear monitors.

Beyond raw power, the GR 2 uses next-generation connectivity and processing to restore the emotional depth of your music. It features JVCKENWOOD’s K2HD Technology to reconstruct lost high-frequency details, alongside a selectable 'K2' mode for enhancement without upsampling. Complete with Bluetooth 5.4 (aptX Lossless), a battery-preserving hybrid power mode, and Nexis app control, it stands as an incredibly adaptable portable audio command centre.

A New Generation of Portable Audio
The iDSD GR 2 builds upon the award-winning legacy of the xDSD Gryphon, completely reimagined from the inside out. This updated architecture strips away traditional processing bottlenecks to unlock the true potential of your high-resolution library. By combining flexible input switching, elite decoding, and massive amplification into a pocket-sized design, it sets a brand new benchmark for what a premium true-portable system can achieve.

Burr-Brown PCM1795 Architecture
As our first design to utilize the premium Burr-Brown PCM1795 chipset, the GR 2 delivers true 32-bit resolution with ultra-low distortion and expanded dynamic range. This sophisticated current-output DAC provides the organic, smooth presentation iFi is celebrated for, while granting our engineering team complete freedom to craft a bespoke analogue stage. The result is a transparent digital conversion that uncovers hidden textures in your music.

Discrete Class A Amplification
The completely redesigned analogue engine features custom Class A op-amps within a fully balanced, end-to-end circuit layout. This premium signal path minimizes crosstalk and distortion to unleash an immense 1,513mW of RMS power, providing the headroom required for demanding full-sized headphones. Additionally, the upgraded iEMatch circuitry utilizes low-impedance MOSFETs to guarantee a dead-silent, hiss-free background for sensitive in-ear monitors.

Intuitive Touchscreen Control
Say goodbye to complex button combinations and tedious menu diving. The GR 2 introduces a vibrant colour OLED display with a highly responsive capacitive touchscreen interface. Crucial system settings, digital filter adjustments, and input selections are brought directly to the surface of the device, making real-time audio tweaks exceptionally fast, clear, and tactile.

JVCKENWOOD K2 & K2HD Processing
To counteract the sterile, flat nature of standard digital files, the GR 2 incorporates JVCKENWOOD’s legendary K2HD Technology to revive authentic harmonic depth and tone. This processing intelligently reintroduces the subtle high-frequency elements lost during the recording process. For absolute purists, a secondary 'K2' mode applies this organic enrichment without upsampling the underlying audio file.

Intelligent Power & App Expansion
A smart hybrid power management system prioritizes external mains power during desktop sessions, drawing from the 4,900mAh battery only during massive transient peaks to shield the internal cell from premature degradation. The device is also fully compatible with the iFi Nexis app for seamless over-the-air firmware updates and advanced tuning, with expanded USB-based control options available exclusively for Android users.
