iFi's high-end DAC is "a portable powerhouse" aimed at audiophiles who want "uncompromising sound"

iFi has unveiled the iDSD GR 2 portable DAC and headphone amplifier.

Acting as the spiritual successor to the brand's high-end xDSD Gryphon, the new model is, says its maker, "a portable powerhouse designed for audiophiles who wants uncompromising sound beyond the confines of the desktop".

The new iDSD GR 2 has been rebuilt from the ground up, with both internal and external developments making for a unique model. At the heart of the GR2 is a Burr-Brown PCM1795 DAC chip, designed to produce a "warm, analogue character" with "lower distortion and greater dynamic range".

That Burr-Brown DAC is supported by 'K2HD' technology, a harmonic restoration algorithm that aims to brings recordings closer to their original intention by "reintroducing subtle detail" and restoring musical depth and tone.

For physical connections side, the iDSD G2 offers digital SPDIF USB-C inputs, as well as 3.5mm and 4.4mm headphone ports. If you prefer wire-free, Bluetooth streaming with aptX Lossless and LDAC codec support allows for streaming of hi-res files up to 16-bit/44kHz.

The new DAC features a new hybrid power mode, so that when the unit is connected to an external supply, it prioritises mains power. If extra power is needed, the GR 2 will use the internal battery and then switch to the external supply when the demand drops.

The GR 2 uses the iFi Nexis app, through which you can access digital filters, fine tune your listening profile, select input and access over the air updates.

The iFi DSD GR 2 is available now, priced at £529 / $529 / €549. For context, the xDSD Gryphon launched at £599 / AU$699 (roughly $815) back in 2021.
