Headroom, Unlocked.
As well as physical control through the new interface, we’ve also unlocked greater control over what you hear.
The iDSD GR 2 delivers up to 1,513mW RMS output — 50% more headphone drive than the xDSD Gryphon — giving it the headroom to handle more demanding loads with ease.
Bass stays composed, transients remain defined, and dynamics open up more freely, even with harder-to-drive headphones.
Better Bluetooth.
GR 2 marks a new generation of portable audio, now paired with a new generation of Bluetooth performance through 5.4 and aptX Lossless. Together, they deliver a wireless experience that can preserve full detail at CD quality (44.1kHz, 16-bit).
For those looking for the highest available bitrate before going fully lossless, LDAC ensures premium-quality listening with bitrates of up to 990kbps.
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. Due to iOS limitations, all USB-based iFi Nexis functionalities are additional features exclusive to Android devices.
