The iFi iDSD GR 2 is the ultimate solution for on-the-go audiophiles, boasting impressive power, exceptional performance, and a brilliant OLED touchscreen display. Its K2HD restorative tech, great XBass and XSpace filters, and impressive build quality only help it to improve on the already impressive xDSD Gryphon, and it even has a lower list price than its predecessor at launch. You can’t ask for much more than that.

With the iFi iDSD GR 2, a seemingly arduous task was at hand. British hi-fi brand iFi had to produce a portable DAC/amp that could improve on the spectacular xDSD Gryphon, which we handed a rave five-star review. But boy, did they pull it off.
The iDSD GR 2 provides upgrades that feel meaningful, practical, and tangible. It delivers around 50% more amplification power than its predecessor, making it easier to drive more demanding headphones, all while providing enhanced dynamic range and lower distortion. What’s more, it adds K2HD tech, licensed from JVC Kenwood, which helps to restore warmth and musicality that digital recordings sometimes lose.
Oh, and it fixes our only major gripe with its predecessor, by adding a vivid OLED touchscreen display, making it feel intuitive and easy to use when switching sources, toggling XBass and XSpace processing, or accessing settings. As a result, it easily competes with the best headphone DACs that money can buy.
It's a fantastic performer, delivering articulate, layered, and balanced sound. I paired the DAC/amp with the Astell & Kern A&ultima SP4000 music player and a range of headphones/IEMs, including the Sennheiser HD 600, and the results blew me away. The GR 2 supplied intricate instrument separation, punchy bass, phenomenal mid-range clarity, and expressive treble, making for a captivating listen, no matter what genre I threw at it.
What’s more, the DAC/amp has higher battery capacity (4,900mAh) with adaptive power, meaning I could indulge in long listening sessions without interruption. Combine that with a neat companion app, numerous connectivity modes, and a lightweight feel, and the GR 2 is the ideal device for audiophiles to carry while on the move.
At launch, the iFi iDSD GR 2 is cheaper than its predecessor was at the point of release, despite making a whole host of improvements. And while it would’ve been nice to see a case bundled in at this price-point, and while there are cheaper options on the market, I still think this model offers impeccable value for money when considering the sheer volume of tech crammed into this little device. As a result, it’s all too easy for me to recommend the GR 2.
The iFi iDSD GR 2 released in June 2026, and is the spiritual successor to the brand’s popular portable DAC/amp, the iFi xDSD Gryphon — a model that hit the market back in 2021. Despite offering a number of upgrades over its predecessor, the GR 2 is cheaper at launch, coming in at $529 / £529 / AU$849.

The iFi iDSD GR 2 is rammed with features, and improves significantly on its already impressive predecessor.
Some of the most captivating options are back, including XBass and XSpace filters, which you can use in tandem or individually. XBass provides a tasteful bump to low-end sounds, while XSpace aims to deliver a more expansive soundstage — both work brilliantly, and I found myself using them often for more hard-hitting hip-hop and dance tracks.
You can select these via a new OLED touchscreen interface, which is phenomenally responsive and very easy to use. Here, you can access a range of settings, including Bluetooth pairing, dual charge mode, a voice prompt toggle, volume sync and more. The main menu also enables you to sift through the GR 2’s vast array of sources, such as Bluetooth (with higher-res aptX Lossless and LDAC support), USB-C, optical, coaxial, and line in. There’s also a lock button if you want to avoid accidental screen touches.
On top of this, the model features dedicated 3.5mm and 4.4mm headphone ports and a USB-C charging slot. Speaking of charging, it will take about 3.5 hours to get to 100% from flat, which isn’t particularly impressive, although I still found that I got quite a lot of playtime from the GR 2 without having to juice it up. That’s because the model features an upgraded battery capacity of 4,900mAh, which should be good for around 7 hours of use — though this will vary depending on volume and if you’re using sound filters.
You can use the GR 2 while charging it via its dedicated USB-C port, a very useful feature if you find you’re indulging in long listening sessions (as I did during testing). The DAC/amp also brings a new adaptive power feature to the table, which balances external power and battery operation. So, if you’ve got the GR 2 hooked up to an external supply, it can prioritize mains power, and in the case that additional power is required, it can be drawn from the device’s battery. The GR 2 will also automatically return to external power if demand drops.
