IFi IDSD GR 2 Portable DAC/Amp With AptX Lossless (IF0310006)

iFi iDSD GR 2 Portable DAC/Amp with aptX Lossless (IF0310006)

The iFi iDSD GR 2 delivers high-resolution audio and powerful amplification, while its compact design keeps listening portable. Moreover, the Burr Brown PCM1795 chipset and balanced amplification provide detailed, controlled sound. Meanwhile, Bluetooth 5.4 with aptX Lossless adds flexible wireless connectivity. Finally, its colour touchscreen makes everyday control simple, whether you use headphones or a home audio system.

Burr Brown PCM1795 DAC for Detailed, Natural Sound

The iFi iDSD GR 2 uses a Burr Brown PCM1795 DAC, while delivering true 32-bit resolution and lower distortion. Moreover, its current-output design gives the analogue stage greater flexibility for a warm, natural sound. Meanwhile, PCM 768kHz and DSD512 support handle high-resolution audio formats with ease. Finally, the result is detailed, smooth playback that keeps musical nuances clear and engaging.

Fully Balanced Amplification with More Headphone Power

Some headphones need more power to perform at their best. The iFi iDSD GR 2 addresses that challenge with up to 50% more headphone drive than the original xDSD Gryphon, delivering greater headroom and improved control.

Its fully balanced architecture extends through the amplification circuitry, while Class A op-amps help maintain a natural analogue character. Refined circuitry reduces distortion, and upgraded iEMatch technology uses low-impedance MOSFETs for more consistent performance.

With up to 1,513mW RMS balanced output at 32 ohms, the amplifier provides the power needed to handle demanding headphones while keeping bass controlled, transients defined, and dynamics expressive.

Bluetooth 5.4 with aptX Lossless Audio

Want the convenience of wireless listening without sacrificing CD-quality detail? The iFi iDSD GR 2 combines Bluetooth 5.4 with aptX Lossless technology to support lossless 16-bit/44.1kHz audio transmission when paired with compatible devices.

It also supports LDAC with bitrates up to 990kbps, providing another high-quality wireless listening option. Additional codecs include aptX Adaptive, aptX, LHDC/HWA, AAC, and SBC, giving you flexibility across different Bluetooth sources.

K2HD Technology Restores Musical Depth

Digital recordings can sometimes lose subtle harmonic information during the digitisation process. The iFi iDSD GR 2 incorporates JVCKENWOOD's K2HD Technology to restore harmonic content, tonal richness, and musical depth that may have been lost.

Think of it as bringing back the finer textures of a recording. Rather than simply increasing volume or emphasizing certain frequencies, K2HD works to recover the natural character and nuance of the original performance.

For listeners who prefer a more subtle adjustment, K2 mode provides similar enhancement without upsampling.

Intuitive Colour Touchscreen and iFi Nexis Control

Managing audio settings shouldn't interrupt your listening experience. The iFi iDSD GR 2 features a capacitive TFT LCD colour touchscreen that places essential controls directly at your fingertips.

Instead of navigating complicated menus, you can access core functions through a responsive interface designed for speed and clarity. The touchscreen can also be locked while you're on the move.

For additional customization, iFi Nexis compatibility provides access to advanced settings and over-the-air updates. This allows the device to receive future refinements, features, and improvements.

Note: All USB-based iFi Nexis functionalities are additional features exclusive to Android devices.

Hybrid Power Mode for Flexible Listening

The iFi iDSD GR 2 introduces an intelligent hybrid power mode that balances external power with battery operation. When connected to an external power supply, the device prioritizes that source and draws additional energy from its battery only when needed.

Once power demand decreases, it automatically returns to external power. This approach reduces unnecessary battery cycling during extended listening sessions.

Its built-in 4,900mAh lithium-polymer battery provides approximately seven hours of playback, while USB-C charging takes approximately 3.5 hours with a suitable power supply.

Versatile Digital and Analogue Connectivity

From portable headphones to a wider home audio system, the iFi iDSD GR 2 offers several ways to connect your favourite equipment. Its combination of digital and analogue connections makes it adaptable to different listening setups.

• USB-C digital input for compatible audio sources
• Optical and coaxial S/PDIF digital connectivity
• Bluetooth 5.4 for wireless audio playback
• 4.4mm balanced and 3.5mm single-ended analogue inputs
• 4.4mm balanced and 3.5mm single-ended line outputs
• 4.4mm balanced and 3.5mm S-Balanced headphone outputs

Whether you're using it as a portable headphone amplifier or integrating it into a larger listening system, these connections allow you to move between different sources without changing your entire audio setup.

Compact Design Built for Portable Audio

The iFi iDSD GR 2 measures 141 x 75 x 19mm and weighs 268g, while keeping advanced audio features portable. Moreover, its compact size works well for listening on the move, at home, or at a desk. Meanwhile, flexible connections and controls support different setups. Finally, it delivers powerful headphone amplification and high-resolution conversion without requiring a large desktop component.
