Sound Your Way: XBass, XSpace & K2HD
The GR 2 puts real-time sound shaping directly in your hands with iFi Audio's suite of analog and digital enhancements–and you don't have to choose just one.
XBass adds low-end extension and weight to the sub-bass, delivering a fuller, deeper presentation. Bass-heavy genres impact and authority, while the overall tonal balance remains controlled and musical. XSpace expands the soundstage, recreating the dimensional quality of a live performance. Congested midranges open up, giving instruments room to breathe and fine details space to emerge. It's ideal for vocal-centric recordings or tracks that feel compressed.
K2HD Technology from JVCKENWOOD restores the harmonic depth and tonal richness that digital recordings can strip away. It reintroduces subtle detail lost in digital conversion, making playback feel less processed and more connected to the emotion of the original performance. K2 mode offers a lighter touch without upsampling, while K2HD delivers the full restoration.
The GR 2 also includes iFi's selectable digital filters, including GTO (Gibbs Transient Optimized), giving you additional control over transient response and high-frequency presentation. Enable one enhancement, combine them, or turn them all off. With a tap of the touchscreen, you can customize your listening experience to suit each new track.

Despite its compact footprint, the GR 2 fits effortlessly into almost any listening chain. USB-C, S/PDIF coaxial and optical, Bluetooth, and a dedicated analog input give you the flexibility to connect various sources, from a laptop at your desk to a full-fledged hi-fi system.
The headphone amplifier drives both a 4.4mm balanced and 3.5mm se output, extending versatility whether the GR 2 is driving high impedance headphones on the move or serving as the heart of a wider setup. Bluetooth 5.4 with aptX Lossless delivers a wireless experience that preserves full CD-quality detail at 44.1kHz/16-bit. Additional codec support includes aptX Adaptive, aptX HD, aptX Low Latency, LDAC, HWA/LHDC, AAC, and SBC–covering virtually every wireless standard available. Wired or wireless, nothing gets left behind.
Power That Adapts.
The GR 2's 4,900mAh battery delivers approximately 7 hours of playback on a single charge via USB-C charging, backed by a hybrid power mode that intelligently balances mains and battery operation. When connected to an external supply, the GR 2 prioritizes mains power first, drawing from the battery only when extra headroom is needed, then automatically returning to external power once demand drops. The result is extended listening sessions without unnecessary battery cycling, preserving long-term battery health.
Upgrading from the Gryphon?
The GR 2 isn't just a cosmetic refresh–it's a generational leap in every category that matters. The fully redesigned signal path with the PCM1795 chipset replaces the Gryphon's MultiBit DAC, delivering measurably lower distortion and a cleaner, more resolving tonality. Power output jumps dramatically with a fully balanced architecture from end to end and Class A op-amps for more consistent performance.
Add Bluetooth 5.4 with aptX Lossless, integrated iEMatch, K2HD Technology, and the new touchscreen interface, and the GR 2 represents a fundamental step forward. Whether you're coming from the iFi Audio xDSD Gryphon or xDSD Gryphon Black, stepping up from a Hip-DAC2 or xCan, or experiencing iFi Audio for the first time, the GR 2 is built to elevate every aspect of your portable listening experience. And if you've invested in an xDSD Gryphon case, the GR 2's similar form factor keeps it feeling familiar in hand.

PCM1795. Pure Conversion Magic.
At the heart of the GR 2 MT is the same Burr-Brown PCM1795 DAC chipset that defined the sound and design of the original iDSD GR 2. It delivers the warm, analogue character we’re known for, but elevated with true 32-bit resolution, lower distortion, and greater dynamic range.
As a current-output DAC, it gave our engineers complete freedom to design a bespoke analogue output stage, purpose-built to extract the very best from the chipset.
Advanced Amplification
The GR 2’s new DAC chipset offered greater design freedom at the analogue stage, so our engineers set to work on a new approach. Class A op-amps offer a more natural analogue character, while refinement of the circuitry – now fully balanced from end to end – has considerably reduced distortion. iEMatch circuitry has also been upgraded with low-impedance MOSFETS.
The result is simple, but powerful - lower distortion, greater transparency, and more consistent performance over time. The iDSD GR 2 MT takes this philosophy a stage further, with upgraded components worthy of Steve Levine’s iconic sound profile.
The changes begin as soon as the analogue signal is output from the DAC chipset, with precision audiophile-grade resistors improving channel balance and delivering a quieter, more stable soundstage, while Audio Note Keisei capacitors in the amp stage add warmth and richness throughout the midrange. The result is perfection, redefined.
Control, Evolved.
A capacitive touchscreen OLED display brings direct, intuitive control to the surface of the GR 2 MT. This colour screen means core settings are now immediately accessible, removing the need for deep menu diving. The interface has been purposefully designed around speed and clarity, making device adjustments feel natural and responsive.
To infuse the GR 2 MT with an immediate sense of aesthetic prestige, the device logo found beside the touch screen is now fully illuminated – a striking visual statement befitting the design advancements made in the Master Tuned edition.
Headroom, Unlocked.
As well as physical control through the interface, we’ve also unlocked greater control over what you hear.
The iDSD GR 2 MT 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.
Freedom Without Loss.
The GR 2 MT joins our latest generation of portable audio and is suitably paired with a new generation of Bluetooth performance through 5.4 and aptX Lossless.
Together, they deliver a wireless experience that preserves full detail at CD quality (44.1kHz, 16-bit).
For those seeking the highest available bitrate before going fully lossless, LDAC delivers premium-quality listening at up to 990kbps.
From high-resolution audio playback digital inputs and advanced analog connectivity to a hybrid power mode that protects long-term battery health, the GR 2 reimagines what portable listening looks like today. It's iFi Audio's most versatile true-portable yet.

Design
The GR 2 joins iFi Audio's portable lineup with a familiar, yet distinctive look. It shares the body style of the first-generation Gryphon–small with round edges and grooved detailing–but enhances it with a new finish, longer display screen, and overall larger size. The GR 2 is almost an inch longer than the Gryphon and just a smidge slimmer in width and a tad taller, making it easier to hold in one hand or slide into your back pocket.
iFi Audio has swapped out the signature silver finish for a bold charcoal grey, which, in my opinion, is an excellent choice. Silver is safe and black is boring, but charcoal grey is not–at least that's what I'm calling it. It's cool-toned yet rich, and it's got this subtle blue undertone that tricks the eyes. Is it black? Is it gray? Is it blue? Who knows. This new finish creates a harmonious balance between the black display screen and matte black bottom panel.
And if you're looking closely, you might notice some additional tweaks to the chassis. The straight edge connecting the top panel and the front has been upgraded to a beveled edge, making for a smaller front panel. The power/volume wheel is smaller with the same grooved detailing as the overall chassis, and the Hi-Res Audio plaque has been removed from the top. They've cleaned up the back panel, removing the bass presence switch on the OG Gryphon, and opted for black lettering over white.
Aside from its striking new finish and subtle physical tweaks, the GR 2 stands out with its new capacitive touchscreen OLED display. Yes, I know, that was a mouthful. Not only is it larger than before and no longer sporting a mirrored reflection, but it's also colored and a touchscreen!
If you're familiar with how the first-generation Gryphon works, then navigating the GR 2 will be like riding a bike. On the Gryphon, the functionality was rudimentary. You used the large round power button to turn the unit on and off, cycled through inputs and outputs via the button on the control panel, and accessed settings through a series of short and long presses via another physical button. The hardest part was having the patience and eyesight to navigate through the options and read them on the tiny display screen.
Despite the Gryphon being only 5 years old, the technology feels ancient compared to the GR 2. Powering the GR 2 is the same, but instead of using physical buttons to cycle through inputs and outputs, the luxurious touchscreen does the heavy lifting. It's never been easier to change inputs, access settings, enable sonic filters, and mute/unmute the volume–all available from the main menu display. No more Morse code sequences of short press, long press, and short again here! Just smooth sailing from the jump.
It's a natural next step for the hi-fi manufacturer, but this feels like a leap and bound for audiophiles. I'm 27, and I have nearly perfect eyesight. Navigating a tiny display screen isn't difficult, but it's certainly not enjoyable for long periods of time.
And while the footprint of the GR 2 might be small, it's not strictly limited to portable listening. USB, Bluetooth, S/PDIF via coaxial and optical, and dedicated line inputs give you all the flexibility to use the GR 2 in various settings, be it connected to a computer via USB, a small desktop system, or larger 2-channel setup. When it comes time to listen to music with your favorite headphones and IEMs, you've got a few options. The GR 2 comes equipped with two headphone jacks, a balanced 4.4mm and single-ended 3.5mm, plus Bluetooth 5.4 with aptX Lossless for wireless listening. When using Bluetooth, the GR 2 preserves full detail at CD-quality, 44.1kHz playback, and supports LDAC with bitrates of up to 990kbps.
The GR 2 is fully compatible with the iFi Nexis app, available on Android and Apple iOS devices. This is where you'll access advanced settings for additional personalization and enable over-the-air firmware updates that add refinements, features, and improvements.
With a full charge, you'll get roughly seven hours of playback, which is an hour less than the Gryphon, but iFi implemented some neat tech to combat that. The GR 2 introduces a new hybrid power mode that, when connected to an external power supply, prioritizes mains power first. If extra power is needed, it'll then draw from the battery, and automatically returns to external power once the demand drops.
Overall, the design improvements of the GR 2 make for a seamless user experience from start to finish. It comes with two USB Cables–one USB-A to USB-C and one USB-C to USB-C–a protective bag, a quick start guide, and an instruction card. Everything you need to get started and nothing that you won't use.
Sound
Listening at my desk, I connected the iDSD GR 2 to my computer via a USB-C to USB-C Cable, plugged in the Campfire Audio Chimera IEMs using our Silver Dragon IEM Cable, and logged into Qobuz. From my years of testing iFi Audio gear, I'm quite familiar with their most notable spatial enhancements, XBass and XSpace, as well as K2/K2HD–their newest addition. They're great features for those who own gear with different tonalities and listen to many genres. I tend to hop all over the spectrum: hip-hop, pop, indie, psychedelic EDM, etc., so for me it's a huge perk.
The Chimera has a dynamic, engaging sound quality but lacks some of the low-end rumble I enjoy, which the XBass setting makes up for. It took the Chimera's textured, punchy bass response and added substantial weight to the sub-bass. The overall presentation became fuller and deeper. Hip-hop tracks from Don Toliver were more impactful. The sub-bass was beefy and visceral, while the mid-bass had just enough slam and energy to resemble what a live concert with crazy good subwoofers would be like.
XBass and I have a soul tie, and it was very difficult to part from it when it came time to test the other enhancements. Where XBass adds low-end extension and visceral bass, XSpace expands the soundstage, recreating the dimensional quality of a live performance. It's perfect for tracks that sound congested or lack top-end resolution and articulation. While I personally prefer XBass, XSpace has its place in my listening experience, and that's when Frank Sinatra, ABBA, or Enya is playing.
In recent years, I've grown quite fond of Reggae–all shapes and forms. The only downside is how hard it is to decipher what some of these artists are saying. With XSpace enabled, the congested midrange where vocals and instruments collided became wider. More space for instruments to breathe and fine details to emerge beautifully.
But the great thing about all of this is that you don't have to choose one or the other. You can have your cake and eat it too. Enable both at the same time. Turn one off. Turn both off. With the tap of a finger, you can customize your listening experience to suit each new track.
K2HD is a newer technology that iFi Audio has been incorporating in its latest products, and for a while, I didn't get the hype. Maybe because I was too infatuated with XBass, but after testing it out on the GR 2, I can't believe I let it sit on the sidelines for so long.
K2HD is designed to restore the musicality in digital recordings that can get lost in the shuffle. It's one of those things that you might not notice is missing. You just assume that's how your music "sounds." But K2HD reintroduces those lost harmonics for a sound quality that's more vivid, deeper, and engaging. When enabling K2 mode, the difference is so subtle it's barely noticeable, but when I switched over to K2HD, frankly, I was appalled I'd been listening to "that" sound quality and calling it great. K2 mode offers similar enhancements without upsampling, but K2HD is the mac daddy.

This chipset delivers a warm, analog character to the overall sound quality, but elevates it wth true 32-bit resolution, lower distortion, and greater dynamic range. As a current-output DAC, it gives iFi Audio complete freedom to engineer a bespoke analog output stage, so they can extract the very best from the chipset.
Headphone Amplification: If there's one thing an iFi Audio product never lacks, it's power. They've mastered the art of squeezing powerful amplification into compact, portable devices, and the GR 2 is the perfect example. The iDSD GR 2 delivers up to 50% more headphone drive than the previous generation Gryphon, giving it the headroom to handle more demanding loads with ease. The sonic results are evident: bass stays composed, transients remain defined, and dynamics open up more freely, even with harder-to-drive headphones.
The GR 2 introduces a new hybrid power mode that intelligently balances external power and battery operation. When connected to an external power supply, say a USB-C cable connected to your laptop, the GR 2 will prioritize mains power first, and if extra power is needed, it then draws from the battery and automatically returns to external power once demand drops. That means you can leave the GR 2 plugged in for longer listening sessions without constantly cycling the battery.
JVCKENWOOD K2HD: The GR 2 incorporates a newer technology featured in several of iFi Audio's latest products, JVCKENWOOD K2HD. Digital recordings can often lose the warmth and natural richness of the original performance, leaving music feeling flat or clinical, which is the opposite of what we audiophiles are chasing. K2HD restores the depth, tone, and musicality of a recording, reintroducing subtle harmonic detail to bring recordings closer to their original intent.
The result is a more natural, engaging listening experience, with digital playback that feels less processed and more connected to the emotion of the performance. It's a feature that can be turned on and off as you please, with a K2HD and K2 mode available. For those who prefer a lighter touch, K2 mode offers similar enhancement without upsampling.
Comparisons
iFi xDSD GR2 vs. xDSD GR2 MT
Less than a year after the GR2's release, iFi Audio launched an updated version, the GR2 MT. This swift upgrade left GR2 owners contemplating their purchase, but the two units serve two separate customers.
The GR2 MT is built on the same foundation as the GR2. What truly sets it apart is a few finishing touches guided by Grammy Award-winning Producer Steve Levine. Levine used his expertise to fine-tune the GR2's sound quality, adjusting timing, imaging, detail retrieval, and so on so forth. The sonic differences are subtle and truly only noticeable when you're performing an A/B test with both units.
Where the GR2 had a lush, musical midrange, the GR2 MT had a slightly cleaner, almost studio-neutral voicing. The GR2 MT's sonic adjustments can be best described as refinements–a little more detail, sharper imaging, tighter bass, tiny tweaks here and there. Like a head chef in a kitchen putting the final touches on a dish before they send it out, that's Levine's contribution–plus a new digital filter for PCM playback.
With the GR2 already under the knife, iFi Audio went ahead and made some micro adjustments to the PCB material, DAC I/V stage, amplifier stage, and display. Both units use the same Burr-Brown PCM1795 DAC chip, but the GR2 MT features an upgraded op-amp with tantalum resistors for lower noise and more stability.
What's New on the GR2 MT:
Digital Filters: The GR2 MT includes a new Steve Levine filter for PCM playback, as well as the original four digital filters. For DSD playback, the default filter has been revised to a signature DSD filter by Levine.
PCB Material: The GR2 MT uses an aerospace-grade hydrocarbon ceramic PCB in place of the GR2's FR-4 board. This material has near-zero signal loss, so more of the music's fine detail survives its journey through the circuit.
DAC I/V Stage: The GR2 MT pairs the OV4627A op-amp with tantalum resistors, where the GR2 uses the OV2637A and surface-mount resistors. Tantalum resistors are lower in noise and more stable.
Amp Stage: The GR2 MT uses Audio Note Kaisei capacitors in place of standard electrolytic capacitors. Kaisei capacitors are designed specifically for audio and are valued for their natural tonal character.
Display: The GR2 MT adds an illuminated silkscreen logo alongside the same touch screen display found on the GR2.
Deciding between the two units comes down to personal preference. The GR2 is the right pick if you want every feature and all that power for less. As a warm and musical listener who mostly listens to pop, hip-hop, and EDM, GR2's rich midrange is my personal favorite.
But if you listen to vocals, acoustic music, or classical recordings, you might prefer the MT. It’s also a great choice for listeners who appreciate premium components and want something no other device offers, like Steve's two exclusive filters.
iFi xDSD GR2 vs. xDSD Gryphon
While the GR 2 sports a different name from the first-generation xDSD Gryphon Headphone Amp DAC, it doesn't take a rocket scientist to deduce that this is the next evolution of the renowned portable DAC Amp. Regardless of how or why the GR 2 received its new name, it embodies what made the Gryphon a cult classic while ushering in a new generation of technology, features, and aesthetics.
In the design section, I touched on some of the physical differences between the iDSD GR 2 and Gryphon, being the finish color, addition of the touchscreen, redesigned volume wheel, and inputs and outputs. The biggest difference between the two models lies in their core architecture. The GR 2 uses a fully redesigned signal path with a Burr-Brown PCM1795 DAC chipset, while the Gryphon features a Burr-Brown "Multibit" DAC. This upgraded architecture means lowered measured distortion–down to 0.0005% via the line outputs–and an overall cleaner, more resolving tonality. It's still distinctly Burr-Brown, but it's just better.
The GR 2 has significantly more power than the Gryphon, delivering better headroom for planar magnetic headphones, improved dynamics, and more control at higher volumes. It's fully balanced from DAC to preamp to headphone amp, and the integration of Class A op-amps delivers more consistent performance and cleaner transient response. Other incremental upgrades include Bluetooth 5.4 with aptX Lossless support, iEMatch integrated directly into the unit, and K2/K2HD Technology for harmonic restoration.
Should I Upgrade from the Gryphon to the GR 2?
Look, if you're asking me whether it's worth upgrading from the Gryphon to the GR 2, the first thing I'm going to say is this: If you're even questioning it, then you probably already know the answer–it's a yes. But if you want the facts, here they are: every year, hi-fi technology advances. The latest and greatest DAC chip is suddenly replaced by a better, more advanced one, and manufacturers find new ways to pack more features and tech into smaller units.
For the audiophile who uses the same headphones daily and doesn't plan on upgrading anytime soon, then maybe the GR 2's new features and tech upgrades aren't worth it to you. If it ain't broke, don't fix it, right? But, for the listener who finds joy in upgrading, swapping, and testing out new gear, then it feels like a no-brainer.
Much like Apple iPhones, with each new generation, the previous ones become more and more obsolete. The Gryphon might be getting the job done now, but what about in 5 years? 10 years from now, when your headphones demand more power or those firmware updates stop coming out. This isn't just a new finish color on a retrofitted chassis with a touchscreen. These are major improvements in performance, amplification, features, and overall user experience that make a big difference in the grand scheme of things.
And if you're not a Gryphon user, but you're still considering an upgrade from your current DAC Amp, analyze your current setup, assess your needs, and see if the GR 2 fills them. Don't go backward and get the Gryphon because it feels like a safe option. Take the leap, make the upgrade. Your headphones and your ears will thank you.

Verdict
At the end of the day, the GR 2 isn't just a follow-up to the Gryphon — it's a generational leap. iFi Audio took everything that made the Gryphon a cult favorite and rebuilt it from the ground up: a more resolving DAC architecture, dramatically more amplification headroom, an intuitive touchscreen that finally makes portable hi-fi navigation feel modern, and wireless performance that no longer asks you to leave quality at the door. Add in the K2HD harmonic restoration, a sophisticated new finish color, and app-based control via iFi Nexis, and you have a device that feels genuinely ahead of the curve.
Is it perfect? The battery life dips slightly from its predecessor, but for the audiophile who wants a single portable device that handles everything without sacrificing fidelity at any stage, the GR 2 delivers on all fronts.
Whether you're coming from the Gryphon, upgrading from another portable source, or jumping into iFi Audio for the first time, the GR 2 is designed to meet you where you are and take your listening further than you thought portable could go. It's the most versatile, powerful, and thoughtfully designed portable device iFi Audio has ever made. Pair it with one of our Dragon USB Cables like the Black Dragon USB Cable, and you've got a high-quality unit designed for stable transmission regardless of whether you're using your smartphone, a tablet, laptop, or computer. If you're on the fence, step off it.

- CCCraig C.Verified BuyerRated 5 out of 5 stars1 week agoThis unit rocks … literally.
I’ve owned the iFI iDSD GR2 DAC Headphone Amp for a few months now. Amazing ‘bang for the buck’! Paired it with some high end IEM’s and my iPhone 17Pro. Truly remarkable at this price. Easy to use. Compact. Tremendous quality in build, aesthetics, and sound. Good options and flexibility for processing choices too. So far … many hours of happiness!

Volume is restricted.
- RDROBERT D.Verified BuyerRated 5 out of 5 stars1 month agoI am totally amazed with this unit.
IFI GR2.
I have been listening to high end headphones and IEM’s since the 90’s. I have the Shure SE846 with a Questyle M15i and i also have the Etymotic ER4XR with a Questyle M15i for portable use. Both combinations sound great. Until recently i used the original Grado Hemp headphones with the IFI Gryphone. My Hemps cracked so I ordered an IFI GR2 from Moon audio with the new Grado Hemp V2 headphones. This is when the magic happened. In all my listening years I never heard this level of compatibility. The voicing and the amazing imaging totally complement each other. I find that I am making extra time just to listen. I use the iphone 17 pro max with Tidal for the source. The GR2 is a great unit and performs far better than its predecessor. i highly recommend it.
- ABAndrii B.Verified BuyerRated 5 out of 5 stars1 month agoLove it!
Finally I can enjoy my U12T and Abyss Diana V2.
So pleasant.
For music source I use Mac Book Air m4 with Apple Music High Res Lossless streaming.
I do like X-bass and K2HD ( to beat AK SP 2000 for musicality)
