xDSD Gryphon: the new portable standard
Pros: Unmatched versatility
Outstanding design, both physical and functional
Premium build quality
Superb sound quality, both wired and wireless
Cons: Some questionable software 'features' and early firmware issues
Could use more premium accessories
Bluetooth 'bug' prevents LDAC connection on some devices
Once in a while, I come across a product in this hobby that doesn’t quite fit into the normal boxes. iFi’s xDSD Gryphon (or just Gryphon if you’ll allow me) is a good example.

Combining elements from two previous products – xCan and xDSD – and adding some interesting new tech of its own, Gryphon is a new portable DAC and headphone amp platform that combines many different technologies introduced and perfected in other iFi products into a compact, advanced, and very accomplished performer.

In doing so, it ambitiously aims to cover multiple bases for multiple use cases. Whether you want hi-res Bluetooth input (including LDAC support), hardware MQA decoding, a proven multibit DAC with native DSD and DXD support, a fully-balanced amp architecture with 4.4mm inputs and outputs, Gryphon does it all, and much more.

In fact, it tries to do so much that it risks becoming a jack-of-all-trades, but as I discovered in the past few weeks, it pulls it off the juggling act remarkably well, making it far more than the sum of its many parts.


Spec sheet

Before we dive into the review proper, let’s take a bird’s eye view of everything Gryphon:
  • DAC: Hybrid multibit Burr Brown
  • Formats: PCM 768/DXD/DSD 512/MQA Studio Master
  • Outputs (headphone): 4.4mm balanced / 3.5mm single-ended + S-Balanced (3.5mm balanced)
  • Outputs (line): 4.4mm balanced / 3.5mm single-ended
  • Inputs (analogue): 4.4mm balanced / 3.5 single-ended
  • Inputs (digital): USB-C (up to 768kHz), SP/DIF (up to 192kHz), Hi-Res Bluetooth (up to 96kHz)
  • Bluetooth (input only): v5.1 support (SBC, AAC, AptX Adaptive, LDAC, HWC)
  • Battery: Up to 8 hours, separate USB-C charging port and dual digital input/charging port
  • Power output (single-ended): >320mW @32 Ω (headphone); 3.5V variable (line out)
  • Power output (balanced): >1W @32Ω (headphone); 6.7V variable (line out)
  • Output impedance (headphone): <1 Ω
  • THD: <0.005% (1V @ 16Ω)
A boxful of tricks

The unboxing experience is much the same as that of other recent and past iFi products, which is to say very high quality. Gryphon ships in a lidded box, complete with a colorful cardboard sleeve full of specs, features, and lots of pretty pictures. Inside, you’ll find Gryphon covered in a soft wrapper, along with a warranty card, fold-out user guide, a velvet-lined carry pouch, and three cables: two short USB-C to C and USB-C to Lightning cables for connecting to smartphones and tablets, and a longer USB-C to A cable for hooking Gryphon up to laptops and desktops.

I would have preferred a harder protective case (I have one on the way from my go-to case maker, Miter), which would have been a welcome addition for someone like me who babies gear against all manner of domestic household dangers. Also, since Gryphon is small enough to be used in a stack with a phone or DAP, I’m surprised iFi didn’t include any elastic rings to keep the stack together. Quibbles aside, the accessory list is more than sufficient, and any of the add-ons I mentioned should soon be available to buy separately anyway.


Build and design

On seeing Gryphon for the first time, I had two reactions: it really does look just as good in person as it does in the marketing material, and it also looks and feels substantially smaller than I expected it to be for such a full-featured device.

The last iFi DAC/amp I owned was the original Micro iDSD, and that was big, bulky, and rather ugly by comparison. Gone are the industrial lines of the iDSD, replaced by a flask-like two-tone shell with a premium-feeling (and importantly, fingerprint-resistant) space grey matte finish. The case itself is about the same size and thickness as a pack of playing cards, which is to say shorter than a modern oversized smartphone but more than twice as thick. It’s also fairly stocky at 215g, which is understandable given all the tech and components it crams inside the metal shell.

Inspecting the buttons, dials and knobs reveals high-quality, precision mechanical finishes with just enough tactile give for fluid movement and haptic feedback, but without feeling too loose or wobbly (I’m aware of some reports of rattling volume dials, but my unit has no such issues). Four slim rubber feet adorn the base, cleverly keeping it stable on a tabletop and safely raised off your smartphone or DAP when using them as a source.

For all the possible permutations, not a single space, button or knob is superfluous. Make no mistake, Gryphon is a brilliant piece of industrial design, and one that can serve as a blueprint for even more potential functionality in future iterations (more on that later).


Features and functions

It’s worth covering all the buttons and their associated features together, because of how interconnected they all are to each other.

Starting with the most visible of these, the volume dial, not so much a dial as a multi-function knob, acts as an on/off power switch, menu selector (when inside the settings menu), and most importantly as an analogue volume control. Did I mention it can also be used to mute the volume (single press) and, with the latest firmware, gives you full pause/forward/reverse track control when connected with Bluetooth?

The fit and finish of the dial is top-drawer. Turning the dial feels very satisfying and solid with perceptible click-click-click feedback in small intervals for fine (1dB) adjustments, but without ever feeling like it’s going to slip or skip multiple volume steps (unless you turn it faster). The way it’s been positioned slightly forward means you can set Gryphon flat on a desk or hold it in one hand and still turn the dial with a gentle one-finger push or pull, which is very well thought through.

While Gryphon features a variable brightness OLED screen, you can also eyeball the volume level by the colour of the LED ring around the volume dial and the LED light on the dial itself. There are six possible ranges, from mute (no light) through to -2db to +6dB (red). Visually setting the dial to magenta (-56 to -39dB) or green (-38dB to -21dB) is an easy and safe way to know you’re not going to blow your ears off when you hit play with sensitive IEMs or headphones plugged in.


Speaking of which, I’ll be remiss not to mention the elephant in the room when it comes to the volume issues that plagued Gryphon initially. Gryphon includes a new iFi feature called CyberSync that attempts to take control of the volume function from the host device under certain circumstances, so that changes to the volume on the host or Gryphon adjust both devices simultaneously.

It’s a good idea in theory, but as it turns out, a rather confusing (and with the original firmware) potentially dangerous one. For a small number of users, connecting Gryphon to some devices (most commonly Windows PCs but also some smartphones and Macs), and then using certain host software (like Tidal) resulted in a sudden and unpredictable volume spike, setting Gryphon to full volume (6dB +Turbo). As you can imagine, having IEMs in your ears when this happens is not a pleasant experience.

The biggest problem, it seems, was not only a CyberSync bug that caused the dangerous volume jump (thankfully corrected with the latest firmware update), but also the inconsistent nature of the CyberSync adjustments on Gryphon and/or the host device. For example, I can still connect Gryphon to my Macbook Pro running Audirvana, and if my master volume is set high on the Mac, it will be sometimes be adjusted up on Gryphon or down on Audirvana. I’m sure that if I take the time to observe when it does what, I can better predict what’s going to happen, but it’s unnecessarily complicated for a feature that’s meant to simplify volume control.

Since it’s purely a software feature, I’d like to see a future firmware revision that allows me to manually disable CyberSync in the settings menu, and to therefore have the option of controlling the volume from Gryphon independently with any device. Another useful firmware function would be to set a volume limiter on Gryphon, which would at least prevent earsplitting disasters if CyberSync is left unchecked.

All that said, I have never had a single volume-related issue with my Gryphon and MacBook, DAPs or smartphones, but I’d still suggest getting into the good habit of lowering volume level before you hit play.

There are two more mechanical push buttons on the front face – a smaller selector button (furthest right) that switches between input types (more on these later), and a slightly larger button that toggles between the built-in XBass II and XSpace functions (again, more on these later), and also activates the settings menu with a longer press. Opposite the buttons, on the left-hand side of the face, are the two headphone output ports, 3.5mm S-Balanced and 4.4mm fully balanced, sized the same as the adjoining buttons to create a neatly symmetrical layout on the fascia.


There are also two other levers on Gryphon: one on the base that lets you activate two different levels of iFi’s IEMatch technology for sensitive IEMs, and one at the back, which toggles between three different options for the XBass II feature.

Starting with IEMatch, the options are labeled 3.5mm, 4.4mm, and OFF (default), supposedly because the more powerful 4.4mm output requires higher output attenuation than the ‘weaker’ 3.5mm output, although both settings work with both outputs. Since I don’t use IEMatch I didn’t spend much time testing for quality differences between the two, but iFi have since confirmed this is the same IEMatch technology used on its standalone and well-received balanced IEMatch accessory, which makes it a great value-add for sensitive IEM users (notably any IEM from Campfire Audio).


The additional XBass II functionality is quite different, and as far as I know, unique to Gryphon. According to iFi, with XBass II ‘you can select ‘Bass’ and/or ‘Presence’ so that the upper midrange frequencies are correctly added back into your favourite recording’. This is something I would have missed entirely had I not checked what the back toggle was all about. It also means that XBass II is more than just about bass, because it can boost upper midrange independently of bass, a potentially useful feature for IEMs or headphones that dip the presence region but don’t need any bass correction.

Combined with XSpace, which mainly affects the treble frequencies to add more air into recordings, Gryphon now has limited but effective analogue-based EQ toggles for bass, upper-midrange and treble, either independently or together in different combinations. I can personally attest to using all three settings to add flavour to some recordings, and in different ways depending on the IEM or headphone I’m using. The fact that it’s so easy to do, and that the effects are never overdone, makes this a very powerful addition to Gryphon’s feature set.


Even more features

Given the smorgasbord of genuinely useful features packed into Gryphon, perhaps the best feature of all is the DAC itself. When I reviewed iFi’s other new portable Bluetooth DAC/amp, GO blu, I noted the ‘missing’ hybrid multibit Burr Brown DAC that iFi uses for almost all of its products. Thankfully, the BB DAC is back with Gryphon, and with it, the very respectable hi-res decoding numbers and formats I felt were lacking on the smaller dongle, including full PCM 768, DXD 768, and native DSD 512 support.

Admittedly these ultra-hi-res formats are only available with direct USB input, but the fact that they’re available at all is the point here.

The DAC is ably supported by a plethora of hardware and software features, including a customised negative feedback amplification design that iFi calls OptimaLoop, which apparently uses different types of negative feedback circuits for optimal performance. Another amplification tech iFi calls PureWave is meant to be a type of optimised dual-mono balanced topology (previously only found in iFi’s higher-end NEO and Diablo amps) for Gryphon’s balanced inputs and outputs, which in theory reduces distortion and improves linearity.

Switching to software features, Gryphon offers a choice of three DSP ‘filters’ (in fact two filters and one unfiltered bit-perfect mode), selectable via the settings menu from the OLED screen. STD is a moderate digital filter with zero pre-ringing and modest post-ringing properties, while GTO (Gibbs Transient Optimised) is a proprietary iFi digital filter that upsamples all content to 384kHz/352kHz depending on the clock source, with only moderate pre- and post-ringing, which, from what I understand, combines the advantages of oversampled delta-sigma processing without the associated ringing artefacts.


Whether or not you think these filters add anything useful is again entirely up to you to decide, but I have to admit hearing some added clarity and dynamics in the sound with GTO enabled, without the presentation becoming too digital.

Speaking of the OLED screen, this is yet another major feature that’s entirely new with Gryphon, and to my mind changes it from a dumb terminal-like DAC/amp (i.e., every other iFi portable product) to something entirely different, and better. Not only does the screen look really cool, it’s also dimmable, can be switched off, and offers a second, very visible and very easy way to check which settings, volume levels, Bluetooth codecs, and inputs and outputs are active at any one time.

The screen also makes it easy to visually make fine volume changes, and is a good way to double-check you’re not about to blow your eardrums with a CyberSync malfunction. iFi has also gone as far as using special low-power circuits for the screen that supposedly don’t add any interference (noise) to the sound. They’ve even given it a name, SilentLine, if you can believe that.

But aside from being a marketer’s dream device for cool-sounding feature names, Gryphon is undeniably packed full of genuine audio-optimised hardware parts from the likes of Alps, Kemet, MuRata, Panasonic, TDK and Diodes, and I believe the quality of parts reflects in the quality of sound.


Ins and outs

Okay, this is the last stop before we get to the good stuff about sound, but to me, the star of the Gryphon show is quite simply its versatility. By that I mean all the different ways it gives you to get your music in from different devices, and the simple yet powerful ways it lets you push it out again with exceptional quality.

Starting with inputs, Gryphon supports an almost full range of digital and analogue inputs, especially for a battery-powered portable device. These include 3.5mm single-ended and 4.4mm balanced analogue inputs, S/PDIF optical and USB digital inputs, and the piece de resistance as far as I’m concerned, hi-res Bluetooth digital input. There’s even a separate USB-C input port for charging the battery independently, letting you charge up while connected to any other input (though you have the option of charging while connected to the USB-C digital input as well).

For playback, Gryphon features four types of outputs: dedicated 3.5mm (single-ended or iFi’s 3-pole 3.5mm S-Balanced) and 4.4mm fully-balanced headphone outputs, and dedicated 3.5mm and 4.4mm line-outs. To save space, Gryphon’s analogue inputs cleverly double as line-outs, switching function automatically whenever you’re using a digital input (like Bluetooth or USB) at the same time.

Since most of the above is self-explanatory, I want to rather spend some time focusing on what I consider Gryphon’s biggest advantage over other similarly-priced (and even higher-priced) portable DAC/amps: Hi-Res Bluetooth. While Bluetooth input is nothing new, the level at which iFi has implemented and refined its Hi-Res Bluetooth input technology sets it apart from any other Bluetooth-equipped device I’ve heard to date. If GO blu surprised me with the quality of its Bluetooth sound – which was only marginally inferior to its wired input – Gryphon pushes Bluetooth quality even closer.

In fact, the difference in sound quality between Gryphon’s LDAC and USB inputs is so small, for anything but the most focused listening sessions, I don’t even bother to wire it up.


There is a small sting in this tail, however. I found a bug – not in Gryphon, but rather in some source devices, like the LG V60 smartphone and a few other smartphone models – that prioritise the AptX Adaptive codec over LDAC, and therefore won’t allow Gryphon to switch into LDAC mode. While this is a very niche bug that affects a very small number of devices, the solution is seemingly a simple one – allow users to manually enable/disable the various Bluetooth codecs in Gryphon’s settings menu. By disabling AptX Adaptive in Gryphon, the buggy sources will see it as an LDAC device.

Sadly, this is not possible, yet, but I’m reliably told that the feature request has been escalated, and hope to see it made available soon. It’ll certainly return Gryphon to optimal functionality for my use case.

There’s also one more feature I’d like to see added, either to the current Gryphon – if it’s at all possible – or to a future version: Bluetooth transmission. While it might seem counterintuitive to pack Gryphon full of dedicated, high-quality audio components designed specifically for analogue output – only to bypass all of them by switching to Bluetooth – there’s a case to be made for turning Gryphon into the ultimate audio interface with this one, simple tweak. Just a thought, iFi; you can thank me later.

Sound impressions

This is the part where I tell you how amazing Gryphon sounds compared to anything else you’ve ever heard. Seriously though, I always add a disclaimer before discussing how a source device – be it a DAC, amp, or both in this case – actually sounds, because they don’t actually have a sound of their own other than how they control and affect the sound coming from your IEMs and headphones. Give two people two different IEMs and one Gryphon, and you’ll get two versions of what Gryphon ‘sounds like’.

All that aside, I can tell you how I hear Gryphon with my IEMs and headphones, how it compares to other sources I own, and what I think about the overall quality of the pairings based on my own preferences and music choices.

I mainly tested Gryphon using a pair of Sennheiser IE 900 IEMs, but I’ve also made notes on how it sounds with other IEMs and headphones, including Sony’s IER-Z1R IEM and MDR-Z1R headphone. Digital sources included HiBy’s RS6 DAP, LG V60 Thinq smartphone and MacBook Pro. I used a variety of test tracks that I’m very familiar with, including (but not limited to):
  • Lana Del Rey – Dark But Just A Game
  • BEYRIES – Alone
  • Brandi Carlile – The Story
  • Eagles – Hotel California (Live)
  • Agnes Obel – The Curse
  • Bjork – Hunter
  • Daft Punk – Contact
  • James Gillespie – What You Do
  • Jillette Johnson – Bunny
  • Jethro Tull – The Waking Edge
  • Angels of Venice – Trotto


I hear Gryphon to have a fairly neutral and linear tonality, with slight warmth in the lower registers, but overall a clean, balanced, and generally transparent presentation. It follows a similar tuning philosophy to GO blu, which again seems to be a departure of sorts from the company’s more pervasively warmer house sound that it still uses in the Micro iDSD series.

This is not neutral in the sense that it’s reference or worse, lifeless, but rather strikes a very healthy balance between overt cleanliness and musicality. It’s not overly analytical, though it won’t do much to change the analytical nature of IEMs that lean that way unless you make use of its sound-shaping features. Instead, I find it delivers quite a rich palette for IEMs and headphones to work with, excellent timbre throughout, and just the right amount of emphasis without oversaturating the sound.

It doesn’t make sense to break down the bass, midrange and treble response other than to say there’s no obvious boost or dip in any of these frequencies, other than a slight emphasis on note solidity and speed down low, and some added air up top. Whether or not that’s a good thing for you depends on what you’re looking for from a source, and what you’re pairing with it. Personally, I prefer linear and transparent sources that support rather than those which affect specific frequencies and run too warm or too cool.

In saying that, with XBass II (and its midrange-shaping capabilities) and XSpace, Gryphon can indeed ‘correct’ the shortcomings or enhance the qualities of IEMs or headphones that need some tweaking. More importantly, it does this in hardware, not software, so there’s no quality hit to the audio chain.

I found XBass II’s bass impact is more prominent than GO blu’s, but can be tempered down using the Bass + Presence setting. The Presence-only setting is also useful for restoring upper midrange bite to IEMs like IE 900, in cases where its dip in this region is too deep for your liking.

XSpace is less a treble bump and more a subtle spatialisation effect, still affecting mainly the treble region but less obviously so than GO blu. If you’re using IEMs or headphones with limited stage width, depth or height, it’ll give you some much-needed breathing room, but I mostly left it off since stage size is never an issue with my gear.



The key to Gryphon’s technical performance is its ultra-low distortion and noise floor, allowing the technical performance of the IEMs and headphones I used to shine through. I don’t perceive any drop in detail or resolution, and if anything, resolution is slightly improved over the R2R-based HiBy RS6 (I’m splitting hairs here, but the RS6 does cost almost three times as much as Gryphon).

Essentially, you’re not making many – if any – technical compromises to resolution, imaging, dynamics or layering and separation when switching from a higher-end source to Gryphon. Some may perceive a slight drop in stage width compared to higher-power desktop amps, but this really depends on what you’re driving, and how well your IEMs/headphones scale with more power. In every torture-test I put Gryphon through, such as the collision sequence in Daft Punk’s brilliantly atmospheric ‘Contact’, it didn’t skip a beat, keeping the different elements separate but cohesive, and keeping a tight grip on the drivers, be they 7mm in IE 900 or 70mm in MDR-Z1R.

There are caveats to this otherwise sterling scorecard, of course. You will hear a slight drop in technical performance when switching to Bluetooth input, especially when using lower-bitrate codecs like AAC or (shock-horror) SBC. Even with LDAC, with its support for almost 1Mbit of bandwidth, the soundscape will flatten, and the fringes of vocal and instrument transients may not be rendered quite as crisply as they would with a bit-perfect wired connection.

Gryphon is also, ultimately, a highly portable, hand-held source, and as such it won’t give you the same headroom as even a basic AC-powered desktop stack. But again, unless you’re driving large planars or similarly insensitive headphones, you probably won’t notice the difference, especially with easily-driven IEMs.

Even if performance is not 1:1 on par with similarly-priced desktop gear, the convenience and freedom of being untethered from a desk (or phone) outweighs any performance issues. Moreover, Gryphon is less affected by cable power noise issues that can be problematic on desktop sources, and sometimes cost more than the sources themselves to mitigate, so you may in fact find its performance exceeds your desktop gear in some aspects.


Select pairings and comparisons

Gryphon is one of three recent releases in iFi’s portable product portfolio, along with GO blu and hip-dac 2. hip-dac lacks GO blu’s Bluetooth input functionality, but compensates with added power and more robust format support with its Burr Brown DAC and higher-end audio components. Gryphon combines the best features from both devices, and ups the ante across the board: more power, better Bluetooth quality and range, higher-spec components, broader format support, more inputs and outputs, and an overall bigger, better user experience.

Compared to Go blu ($299), Gryphon refines both wired and wireless sound quality. You can step further away from your source when connected wirelessly, and take advantage of higher-res format support, and even questionable software features like CyberSync if you’re so inclined. Both devices are tuned similarly, with a clear, crisp but still engaging and musical presentation, but Gryphon adds more note weight, definition and stage size, and is able to drive bigger and less sensitive headphones. Its sound shaping features and DSP filters are also more robust.

Where GO blu wins hands-down is ultra-portability, and the simplicity of being able to connect-and-forget while on the go, and sound performance is close enough to leave Gryphon at home and take GO blu on the road, even for longer trips.


Compared to HiBy RS6 ($1400), Gryphon takes a different approach sound-wise, being more neutral and transparent compared to RS6’s warmer, fuller and more organic tilt. RS6 does sound more natural with certain genres, especially with vocals, by virtue of its discrete R2R DAC, although Gryphon’s hybrid multibit DAC and features like the GTO digital filter get Gryphon really, really close in terms of naturalness. Gryphon also has more output power and a lower overall noise floor, even though both devices are hiss-free and more than powerful enough to drive all but the most stubborn headphones. In terms of absolute SQ, Gryphon matches RS6 blow-for-blow and is even slightly more advanced technically, with a wider stage and better clarity.

I’ve actually found the two to be complementary in the time I’ve spent with them so far, often using RS6 as my wired and Bluetooth source for Gryphon, especially when I want to use Gryphon’s extra output power. Another benefit of using the two together is connecting them using a balanced cable, effectively combining RS6’s excellent R2R DAC with Gryphon’s powerful, low-distortion amp.

Since RS6 is a self-contained DAP, it has its own advantages over a DAC/amp like Gryphon, not requiring external sources for one, and being able to navigate and manage multiple music sources from the device itself. If you’re after a standalone device for music playback and want to keep your music player, phones and computers separate, then RS6 is an excellent Segway from devices like Gryphon, but if sound quality is your only measure, you won’t lose anything with Gryphon and it’ll cost you significantly less.


I can highly recommend iFi’s brilliantly-made 4.4mm interconnect cable if you’re planning on tethering Gryphon to a balanced DAP or desktop amp – easily one of the best-looking, best-built and best-performing interconnects I’ve had the pleasure of using.


It’s been a while since I’ve used any of iFi’s larger portable devices, and I haven’t had the pleasure of trying out the newer xDSD and hip-dac series for that matter, but I’m confident enough to say that I don’t really see a use case for myself with any of them. Gryphon’s Bluetooth support and quality, for instance, makes the thought of using a wired-only external DAC/amp or dongle unpalatable at best. We’re fast-moving towards a time when wireless source quality will match wired performance, and with Gryphon (and GO blu to a lesser extent), the differences are already too small to warrant wired sources most of the time.

What hasn’t changed is our reliance on wired IEMs and headphones for maximum sound quality. Pairing Gryphon with a good pair of IEMs is the optimal use case for me, and the synergy with both the IE 900 and IER-Z1R is exceptional. But Gryphon is just as adept at powering easy-to-drive full-size headphones, like Sony’s MDR-Z1R. Unless you need the absolute portable freedom (and advanced features) of true wireless IEMs or headphones, you’ll get maximum sound quality with only a small loss in portability using Gryphon as a Bluetooth streamer for your wired IEMs, and if you want to get even more portable, GO blu.


Verdict and closing thoughts

When I first read about Gryphon, I didn’t quite see how it would fit for me, having switched to using IEMs exclusively, and using them exclusively with a DAP. It was GO blu that opened my eyes to the usefulness of a Bluetooth-enabled source for my wired IEMs, especially when I wanted to use my higher-end IEMs on the go. That’s when I joined the dots and fully understood Gryphon’s potential.

In one compact and still (for me) very pocketable device, iFi has evolved the concept of a portable Bluetooth streamer, bringing along all the advantages – and sound quality – of its upmarket wired DAC/amps, throwing in a few extra new and improved features in the bargain. For much less than the cost of a high-end DAP, you can now buy equivalent sound quality, better versatility, and enough power to drive not only IEMs but also full-size headphones, and still be able to move about freely with your music.

From the very first time I used it, Gryphon started changing the way I engaged with my music. For one thing, I credit Gryphon with encouraging me to re-look at getting a full-size headphone as an alternative to my IEMs. Then, using a smartphone with more ‘smarts’ and speed than any DAP, meant I didn’t have to skip a beat between the music player interfaces I’m already familiar with (specifically UAPP on Android).

With its outstanding Bluetooth input quality, I also wasn’t constrained by having to wire up the phone, and in fact, could even use the DAP as a source if I needed the phone for other tasks. And, when I wanted to max out sound quality, Gryphon includes everything I need to wire up my sources in the box.

iFi may have been a bit ambitious in claiming Gryphon as the ‘birth of a head-fi legend’, but I will say it’s easily the best portable device I’ve used in all my time as a portable audio enthusiast. That includes the flagship Lotoo and HiBy DAPs I’ve used in the past (and still use today), both in terms of sound quality but, just as importantly, flexibility, functionality and versatility. It liberates you from worrying about how to get your music in or out, which sources you can connect to, or which IEMs, headphones, or even speakers you want to use, without having to worry that sound quality and driving power will be compromised.

Sure, it had some teething issues, CyberSync being the most obvious and one that I suspect will still take some time to fully resolve. It has some missing parts – a case would be nice, and some stack loops too while we’re at it – and if someone at tech central could please fix the annoying AptX Adaptive ‘bug’ for me that would be much appreciated!

But these are hair-splitting gripes. Gryphon is just about the complete package, and I believe it’s only going to get better as iFi fine-tunes existing (and potentially new) features in firmware. Where it goes from here is anyone’s guess, but knowing iFi, there’s an upgrade path in development, if not already in production. As a version 1.0, Gryphon sets the standard for what’s possible in portable audio today, and I keenly await to see how the platform evolves in the future.

If, like me, you prioritise portability as much as you do absolute sound quality, and don’t want or need the extra headroom (and potential benefits) of full-size desktop gear, then Gryphon is an unequivocal must-buy. Highly recommended.

In fact as reviews go; this one is ‘quality’, for eg:

It also means that XBass II is more than just about bass, because it can boost upper midrange independently of bass, a potentially useful feature for IEMs or headphones that dip the presence region but don’t need any bass correction.
where covering the full extent of the ‘bullet point’ features is determinedly applied to real world usage..

Not trying to review your review; just wanting to establish to any ‘skimmers’ that this article goes a long way to ‘one stop shop’...

:) Cheers

@iFi (not really!) ‘silentLine’? (keeping the power fluctuations associated with screen electronics free from the audio circuit? (yes please!)
gLer I really feel you understand where hardware fits in the market and what users dollars will scale towards. This sort of review is as useful to techheads as it is to casuals, and congratulations are due for bridging these social crowds together- giving something (practical) for everyone. (succinctly even!). You are a source of usefulness (rather than noise). This review HELPS headfi. Outstanding!
You really get the ‘realworld’ product useability out in the open.. and those photos are terrific too. (thanks again)

xDSD Gryphon Review
Pros: Sonic performance & staging, excellent tonality, aesthetically pleasing, BT performance, musicality
Cons: Cybersync (Volume Sync with device), noise floor with ultra-sensitive iems & IEmatch increases output impedance, battery saver doesn't work and no setting to enable it. Sub bass rolloff/freq compression.
Earlier in the Gryphon thread I had posted some early impressions and comparisons of the xDSD Gryphon compared to some other units. While those impressions still stand after a good number of weeks I've become more familiar with the device and would be happy to share my full review. The xDSD Gryphon to me strikes a fantastic balance between neutrality and musicality. The device is linear with a wide sound stage yet doesn't let the analytical nature of modern devices take over. Going forward let's cover my thoughts on the features and sound quality of the device.

As a disclaimer my xDSD Gryphon was purchased personally and was not part of a demo/review program.


The xDSD reminds me of the iDSD BL series in terms of system compatibility - even more so with what they've crammed into this device. 4.4mm is the new standard for mobile friendly balanced (and for good reason) and is the perfect choice for the Gryphon. With it you get the full power for your harder to drive headphones. On the back you've got 3.5&4.4 connections that can either be used as output from the internal DAC or inputs to use the Gryphon as a dedicated headphone amp. XBass&XSpace are rather enjoyable implementations that do not overpower the sound like some previous devices did when enabled. With my stable I did not prefer using these but I can definitely see it's use for certain headphones or perhaps listener preferences.

Easy swapping between USB, SPDIF, BT and Line In are possible with the front buttons, as is accessing the menu and navigating it. It's incredibly easy to get the Gryphon running and the speed of swapping between each of these is blisteringly fast. It's so nice being able to get the Gryphon going in just about any scenario I want with excellent results. Bluetooth performance is exceptional as well with only a minor degradation in sound quality, you'll really have to focus to detect the difference between wired and wireless.

The Volume knob changes colors based on power output easily letting you know where you're at and the tactile feel of it is incredibly pleasing. The buttons are easy to use and the screen brightness can be adjusted. Fit and finish is exemplary and it shows that Ifi took their time on the hardware side of designing the Gryphon. Jacks are all solid and there is little concern for durability with the Gryphon. The screen is bright and clear, and doesn't appear to induce noise which is fantastic. I do wish they'd used glass instead of acrylic as a cover for the screen but, this is a minor nitpick.

**EDIT** The Gryphon has a built in battery saver, this is always enabled. Great job Ifi!
Missing however is an ability for eco battery when used as a desktop DAC/Amp. Ifi states to turn on the device then plug it in so that the unit doesn't charge all the way, though in practice I've not had much luck and you'd have to unplug and turn it off every time you are finished using it, then turn on and plug in when you are ready to go again. There is an option in settings however to have one cable both charge and supply data - which is an excellent toggle addition if you've got clean USB. If the battery charge control would be implemented as a menu option in settings the Gryphon would be a completely desktop friendly device in my opinion.

Cybersync is a feature better in marketing and not so much in practice. This allows the volume of the Gryphon to be controlled by the device it's connected to. Ever accidentally maxed out your OS or phone volume with too long of a button press? Imagine that combined with 1W of power and a set of IEMs. Before a firmware update was provided by Ifi myself and others had experienced volume spikes between tracks in certain players and in other scenarios with the Gryphon. When dealing with 1W of power and a device marketed as IEM friendly this is a big problem.

Firmware has thankfully corrected most of these volume issues, but knowing I could accidentally adjust the volume on my android device while it is in my pocket is a constant worry. What if my phones volume button were to be held down while exercising or moving about blowing my ears out or damaging my IEMs? This concern has made the Gryphon unusable while on-the go and forced it to the desk or sitting positions where I know I've got full control of the environment. A firmware option to remove this 'feature' would be very welcomed.

IEmatch is another feature issue of the Gryphon, though mostly for users of ultra-sensitive IEMs. Unfortunately as a CA Solaris owner I was impacted here. The Gryphon is very powerful, and thus the noise floor presents itself with ultra-sensitive IEMs. The 4.4mm IEmatch setting squashed dynamics and changed the FR of my CA Solaris IEM. Without IEmatch the Gryphon hissed quite loud. 3.5mm is serviceable, though not ideal. The output impedance changes up to almost 10Ohm with IEmatch enabled which is important to keep in mind. With other IEMs I did not have an issue and the Gryphon performed incredibly well.



The Gryphon's signature is more neutral leaning with a hint of warmth. It's decently fast yet not sibilant. I think it's a rather nice balance however I will start with the obvious "Birth of a Head-Fi legend" as being a bit of a marketing overstatement. It's not nearly as fast and detailed as my dedicated desktop devices, though it is important to note the price of the Gryphon is a fraction of what my desktop rig costs.

What does push it towards legendary though is that I prefer it's presentation, sound quality and overall experience to the iDSD BL. For a do-it-all device this puts the Gryphon into being a benchmark for this segment. The soundstage is well represented with fantastic positioning. Instruments are defined and the three blob soundstage of the iDSD BL series is gone. This is replaced by correct placement and significantly more precise imaging. A very slight bit of warmth really helps the package come together. Mids are fluid and come across neutral yet are forgiving. Highs are extended and airy with great sparkle. Bass is engaging and tactile, despite not being the end all in bass resolution I've not heard a device this size present such a fantastic grip on the lower registers. It however does not dig deep into the sub area, pushing focus towards lower mid bass. This is still an incredible accomplishment for Ifi.

As a DAC the Gryphon performs admirably well. Feeding a signal into my Freya S was made easy with a 4.4 to XLR L/R cable. The experience was more than acceptable and I was toe-tapping in no time. The Gryphon is so incredibly close to a do-it-all device leader in it's price segment. As an amp I felt the Gryphon did quite well. I feel that the amp of the Gryphon has it's own sound characteristic - and it's a rather pleasing sound at that. Given the internal DAC performance though I don't see myself using the Gryphon as a dedicated amp. The Gryphon shines as a combo plenty bright.



The Gryphon on a hardware level is a fantastic device. Nothing on the market currently is pushing such a diverse featureset like Ifi and the Gryphon's sonic performance carries it to the skies. Unfortunately software and marketing choices have kept Gryphon from being above the clouds. Ifi can easily correct these issues through updates, aside from the IEMatch/Noise floor - this is a hardware level problem impacting Campfire IEM owners but let's be honest, MOST devices have problems with CA IEMs so this really is a nitpick of compatibility. If Ifi was to offer a Cybersync free firmware and proper battery saving this review would easily be rated higher and I'd be free to use this device on the go, in the chair and at my desk without any issues or concern. If this occurs I shall update my review - thanks for reading!

It does not. 3.5 is serviceable, 4.4 is completely crushed. This is with 4.4 output - 3.5 setting still impacts 4.4.. it's... weird. I'll need to test 3.5mm output on its own. It is likely much quieter.

Hey @Voxata, can you do a quick comparison with your WM1A pictured?
It was in my prior comparison. I prefer the soft modded WM1A for it's unique flavor.

Ifi-Audio produce another great bluetooth DAC/AMP
Pros: Sound Quality
Build Quality
Ease of use
Cons: Minor niggles (although improved with updates)
Disclaimer - I was sent this by Ifi-Audio for my honest opinion, it is not a free sample. I will either send back or purchase after review period.


The Gryphon is IFI-Audio's newest addition to their portable range of DAC/AMPS that can be used either with Bluetooth or wired to a source. My usage has been exclusively with my Samsung S21 Ultra smartphone (UK model). I haven't tested with either of my laptops as I already have options I use with them one being the excellent IFI Senn Signature AMP/DAC duo.

I recently reviewed the GO Blu from IFI and really love the little device, works flawlessly from my phone and drives my IEM's with ease. Liked it so much I bought and found myself using my DX300 DAP less and less, not because the Go Blu was better but just so easy to use and cracking sound quality for the price. I had high expectations for the Gryphon.

Like many others on Head-fi I seem to search for what I consider to be the ideal solution for a source. I always like the idea of a DAP but they inevitably end up disappointing me due to the majority having a reliance on Android, although this always seems appealing I find myself being disappointed due to them not being able to compete with my mobile phone in regards to ease of use and speed of the operating system, I also find that I have issues with the apps that I use for streaming. This always brings me back to the idea of using a DAC/AMP solution with my handset. Over the years I've tried various different options both wired and bluetooth but always find them lacking in some respect, either due to interference issues, sound quality, poor build or various other reasons.

For the last few months alongside the go Blu I had been using a DX300 which I loved the sound quality from but again found issues with Android and software/apps.

The Gryphon

Comes nicely packaged with a little felt like carry case and a usb-c to c cable for connecting to smartphones (Android), and a USB-C to USB-A cable is also included.

The Gryphon itself is a lovely looking unit and very tactile with its ridged body, has a narrow OLED screen that runs the length of unit, this shows sample rate, volume and battery level etc. Buttons and connections are well laid out, 3.5mm SE and 4.4mm balanced on the front of the unit and two usb-c connections on the back, one for charging and the other for connecting to source. There is a S/PDIF connection as well as 4.4mm and 3.5mm analogue connections.
I only used the USB-C connection and Bluetooth so can't comment on the other connections.

Ease of use

There really isn't much to say here, for my purpose it was easy to set up and had no issues with the process, pairing was quick and simple, found my phone with no issues, the whole time I have been using it has held a constant LDAC codec at highest audio setting.
Wired connection with the Samsung S21 Ultra was a little problematic initially due to Samsung's poor implementation of USB Audio drivers and limited sample rates (that's my basic understanding of this). This means that you often hear pops and crackles when playing some tracks from streaming services, Audioquest (similar issue with Cobalt) explained to me that it is a limitation of Android and Samsung that causes this. I've had various DAC/AMPS that have struggled with this if they don't use their own driver.
Using USB Audio Player Pro app is a good workaround, it uses it's own audio driver and can now be opened as an app then it will use it's driver while you use apps such as Apple Music or Amazon that are not supported within the app.

Sound Quality - Wired

Equipment used

Etymotic EVO
Fiio FD7
64 Audio U6T
IMR Elysium
Sennheiser 660s
Mitchell and Johnson MJ2

Some comparisons with Ibasso DX300, IFI Audio Go Blu and very briefly with Astell and Kern SP2000T

Selection of tracks used including

Mogwai - Mogwai fear satan
Mogwai - My Father My King
David Bowie - The Rise and Fall of Ziggy Stardust and the Spiders from Mars album
The Smiths - I Know It's Over
The Smiths - Well I Wonder
The Velvet Underground - Oh Sweet Nuthin
Lou Reed - Waves of Fear
The Wedding Present - various tracks
Belle and Sebastian - various tracks
Pet Shop Boys - various tracks
New Order - various tracks
Martin Rossiter - Three Points on a Compass and Drop Anchor

Most tracks were streamed in their possible quality from either Amazon HD, Tidal or played from memory on the handset.

Low/Bass response - The Gryphon does a really good job of pairing well with all of my earphones to produce accurate bass that is never overwhelming but will give a kick when the track requires, an example of this being the two Mogwai tracks, Mogwai's music to me has a constant low frequency rumble especially when listening to live versions of the tracks, the gryphon reproduces with great accuracy and depth, bass is detailed and layered with excellent sub bass response.
Bass on electronic tracks from Pet Shop Boys and New Order is snappy and again very accurate.

Mids - These are probably the stand out for me, smooth and detailed which is how I like my mids to be on any device. In a similar vein to the bass response the mids are very accurate and never feel forced or unnatural. They don't sit far forward in the mix either, on the Martin Rossiter tracks which are just vocal and piano the mids are simply stunning, the emotion in his voice coming through wonderfully.

Highs - Starting to sound repetitive but again these are wonderfully presented and don't stray from the natural sound of the rest of the frequencies, guitars on Wedding Present songs have the crunch and snarl I would expect from them and the punch of guitars from Mogwai on their quiet/loud presentation is again stunning. The highs don't add anything extra that they shouldn't, if anything they may be slightly laid back compared to the other two but that maybe just to my 50 year old ears, and when I say slightly laid back that is a mere smidgen, if anything I probably hear this on all of the IFI equipment I have owned/tried. I always consider them to be a fairly natural sound with an excellent musical presentation and it's maybe this slight laid back approach of the highs that create this sound.

3.5 S-Balanced and 4.4mm connections both sound excellent to me, I had no issues with any hiss or background noise, clean signal at all times to my ear and headphones. The 4.4mm connection is the one I probably used most and it provided plenty of headroom and power to my Senn 660s. Never had to go above 70-75% on either connection, Etymotic EVE sounded wonderful from the 3.5mm, as is usual with Etymotic, the more power you give them the better they reward you and the Gryphon was no slouch with them.

Soundstage and depth is very good, competes with my DX300, maybe not quite as depth but not far off.

Features such as IEM match, Xbass and Xspace I only briefly tried. Probably not enough to really comment, xbass gives a little boost to the low end but I never felt I needed to use it.


As can be seen from the specs the Gryphon supports a wide range of Bluetooth codecs, my use was with the LDAC codec and it never skipped a beat. Connection was reliable with no drop outs even when going into a different room, a lot better than my Go Blu that can drop out at times when using LDAC.
Sound quality from Bluetooth is virtually identical to wired, there is a difference but it's barely noticeable unless you are really scrutinising. It is by far the best wireless sound quality I have heard from a device.
There isn't much I can add to the wireless thoughts really, it is quite simply stunning.

Brief comparisons

IFI-Audio Go Blu - Different level really, don't get me wrong the Go Blu is an amazing device for the price but it can't compete either wired where it's support for higher sample rates is limited and although it is excellent as a bluetooth device it doesn't sound as good as the Gryphon, less power and not as detailed and less depth to the overall sound.

Ibasso DX300 - Now this is really interesting and there will be people who won't believe this but in many respects the Gryphon is as good as the DX300. The level of detail in the mids and highs competes with the DAP, the bass response is also more natural to my ears but maybe not as deep as the DX300. Overall soundstage and depth goes to the Ibasso but I found myself reaching for the Gryphon more as the weeks progressed, partly because it's a snappier experience with the high end smartphone but also because it just sounds so good and despite being half the price it runs the Ibasso close.

Astell and Kern SP2000T - Now this is very brief as I've only had it a few days but again like the Ibasso the Gryphon does a good job against a player that is 3 times its price however I think the gap is bigger. The AK SP2000T with it's tube/hybrid amp mode gives it an edge that neither the Gryphon or DX300 can match. The level of detail in the mids and highs on the AK are a different level of stunning, however this is probably not a fair match up.

Reported issues

There has been some reports on the Gryphon thread of issues with build quality around buttons (only 2 users i think) and volume spikes when using Tidal.
I've had no issues with build or quality control, it is built like a premium product and feels like it, buttons are excellent with no rattles etc.
I did experience the volume spike once when starting Tidal but never between songs or during songs. It happened when I connected in a certain way, never happens if I connect in a slightly different way and it hasn't happened since latest firmware update.
Some mis reporting of sample rates on the Amazon HD music app however this is something that happens on my DAPS and on smartphone, seems to be an issue with the Amazon app which is a truly terrible app.
No issues with Apple Music (only briefly tried) or Tidal (since update)

Overall impression

I've really enjoyed my time with the Gryphon, to me it is a potential replacement for those who don't want to use DAP's especially if you are mainly a music streamer. The sound quality and ease of use was was enough to make me sell my DX300, not because it was better but because for a fraction of the cost I could get within a certain percentage of the sound quality. Despite this I did buy the AK as I was curious about the triple amp system, I will keep the AK and need to decide if I will buy the Gryphon....Chances are I probably will, it gives me enough of a different sound experience and I'm more likely to use it outdoors than the AK so it will serve me well in that respect.

The Gryphon is another great product from IFI Audio that ticks all the boxes in regards to build, ease of use and most importantly excellent sound quality

Appearance and kit

xDSD Gryphon comes in a presentable white box, the top of which is a print wrap. Above is the brand logo, next to it there are already two golden stickers, Hi-Res Audio and Hi-Res Audio wireless, in the center is a photo of the device in all its glory, and below is the designation of the model and its type of activity: xDSD Gryphon - Ultra-Res portable DAC + Headphone amp.


A complete list of technical features and specifications can be found on the side and back of the package.
Next, put forward a boiled white box with silver letters "ifi". Everything, as always, with my beloved Britons - stylish, laconic, neat, but without the slightest hint of boring stiffness.

With trepidation, we open the box and extract all the contents from it: the xDSD Gryphon itself, three connecting cables (USB type-C / USB type-C, USB type-C / Lightning, USB type-C / type-A), then we take out the fabric case, an "iFi" sticker, instructions and a warranty card.


Well, now let's get down to admiring the device, without this, in the case of iFi creations, it is absolutely impossible.
Like its predecessor, the first xDSD, Gryphon received an original and striking appearance. It resembles an exquisite cigarette case or flask with longitudinal ribs. However, a number of key points have been improved here.

To begin with, the dimensions of the device have slightly increased (123 x 75 x 19 mm), its weight is 215 grams, the color is now silver-gray matte metallic, the material is aluminum. Looks Gryphon, I want to tell you, unusually beautiful, but in the hands it feels even better!


The upper part has taken over a nice oblong OLED screen, which displays all the necessary information about the format being played, connection, battery level and additional functions.

On the front panel of the device there are two headphone outputs (3.5 mm TRS and 4.4 mm Pentaconn TRRS balanced), two indicators that display the selected input and the frequency of the reproduced signal, and a round volume control with a small LED signaling the level in different colors signal. The regulator, in combination, is also a button, when pressed, the device turns on / off. Slightly to the right are two indicators of the XBass + (bass increase) and XSpace + (space expansion) modes, the button for switching these modes, which, when pressed for a long time, takes us to the function menu (all information is displayed on the screen): Selecting a digital filter - Standard / Bit-Perfect / Gto; Voice assistant; Adjust the brightness of the screen; Dual USB Type-C charging capability, and reset function. Next comes the button for switching inputs: USB / BT / SPDIF / Line-Out. She, when pressed for a long time, searches for devices for pairing via the Bluetooth protocol. All information is clearly displayed on the screen of the device.



On the rear panel there is a switch (Bass / Presence), a USB type-C connector for connecting a power adapter and charging the device (under it there is an LED indicating the battery charge level), digital inputs: USB type-C and S / PDIF, and also two analog line outputs: balanced 4.4mm (BAL) and 3.5mm (SE).

The bottom side received a three-position iEMatch: switch (3.5mm / 4.4mm / Off) and four silicone feet placed at the corners of the device. The back side of the case, where the BT-receiver is located, is covered with plastic, as a result of this approach, there should be no problems with the wireless signal.



The build quality raises no objections, no backlashes and gaps. Everything is extremely reliable.
Separately, I would like to mention the chic volume control, reminiscent of a flask lid, with precise, "clacking" adjustment, an unusually smooth ride and a multi-colored LED.

The battery, when switching between different digital signal sources (USB / Coaxial / BT), on average, lasts about 8 hours. Charging time takes approximately 4 hours.
As I already mentioned, the battery charge level is shown on the screen, and is also highlighted by an LED on the back of the device (a handy thing, especially if you charge the device in the off mode):
Green:> 85%
Yellow: ≤ 85%
Red (flashing): ≤ 10%
The indicator flashes / lights up while the device is charging.

Now let's summarize what's new in the second version:
1) Informative OLED display.
2) 4.4mm Pentaconn balanced output (TRRS).
3) High power of the device.
4) Bluetooth 5.1 QCC 5100 / (codecs: aptX, aptX HD, aptX Adaptive, aptX LL, LDAC, HWA, AAC and SBC).
5) Full support for MQA x16 up to 384 kHz.
6) Choice of digital filters: Standard, Bit-Perfect, GTO.
7) Improved work of functions: Xbass + and Xspace +.
8) iEMatch for 3.5mm / 4.4mm.
9) New volume control.
10) USB type-C charging and USB type-C digital input
11) Updated design.
12) Kit.

With such updates, Gryphon can honestly be considered a completely new product!
At the same time, we have not yet reached the main reason for which this review was written - the "voices" of our hero. And here, I want to inform you, the most impressive leap has occurred. But let's talk about this a little later.



When connecting the device to a computer via USB, it is recommended to go to the manufacturer's website and install the appropriate USB audio (ASIO) driver. The driver is downloaded and installed quickly. After installing the driver, an icon with the iFi brand logo appears in the tray and the system automatically finds the xDSD Gryphon. If you, like me, use the foobar 2000 software player, go to preference / output and select the device we need from the list. I also recommend updating the product software (firmware), which is also posted on the manufacturer's website in the "support" section. Personally, when I received the device, I fully charged it and immediately rolled the new firmware.

My scenario for using the device turned out to be the following: xDuoo x10t II digital transport via S / PDIF (optics, coaxial), Huawei p20 pro smartphone (USB) using the UAPP software player + Bluetooth (HWA) connection, Samsung Galaxy Tab S7 plus tablet - Bluetooth (LDAC), PC via USB with foobar2000 player (Asio iFi driver). In all these cases, no problems arose.

Well, we seem to have figured out the kit, appearance and functionality, now we raise our wings and fly forward to the sound heights!

Sound Impressions

The xDSD Gryphon's capabilities are impressive without any caveats, both for wired and wireless connections.
The device is built on a Texas Instruments Burr-Brown DSD1793 DAC chip.
Before listening, the device was burn-in for about 70-80 hours.

We used: Beyerdynamic DT250/250, Phonon SMB-02, Phonon 4400, Softears RS10 & RSV, FIR Audio M5 & VxV, 64 AUDIO A12t & A18, Vision Ears VE8, EVE20 & VE4.2, InEar ProMission X & ProPhile 8.
Mostly the 3.5mm output was used, with the exception of the IEM FIR VxV which was connected to the 4.4mm balanced output.
The device played very well with all IEM / CIEM / Headphones, no genre deviations were noticed.

Digital signal sources: Dell XPS laptop, Huawei P20 Pro smartphone + USB Audio Player PRO, Samsung Galaxy Tab S7 plus (BT), xDuoo X10t II portable digital transport.


Let's start with impressions when using USB and S / PDIF connections.
In fact, it is quite difficult to describe the sound of the device, which is almost impossible to find fault with.

From the very first minutes of listening, the device takes a rather serious approach to sound production, demonstrating excellent dynamics, practicing attacks, separating instruments, as well as working out plans, with a stunning transfer of the volume of an imaginary space. This is a neutral, well-balanced and unusually melodic manner of conveying the material.


The device transmits well the timbre component, the development of quiet and loud sounds, reverberations, as well as macrodynamics with a moderate, sensitive display of micro-contrast.
Gryphon does not try to push forward all the smallest details of the composition, he does it delicately, correctly outlining the volume of virtual space, portraying audio images harmoniously and proportionally, in a balanced and extremely naturalistic way.

In terms of the "level of competence", so to speak, the sound of xDSD Gryphon gravitates to what the flagship iFi shows us - iDSD Diablo, but in terms of sound habits, their handwriting, their manners are still different.

Where the older brother strikes with scale, conveying the width of an imaginary soundstage and his analytical manner of presenting material, Gryphon, with a slightly restrained rendering of the width of space, takes depth, conveying volume and macrodynamics. That is, switching from iDSD Diablo to xDSD Gryphon is not perceived as a transition from a higher quality sound source to a lower quality one. Rather, it is like comparing two exemplary audio systems with partially similar and at the same time different manner of sound delivery, realized in different acoustic conditions.



And, of course, it is worth noting here the fact that the scenario of using the iFi iDSD Diablo with sensitive IEM/CIEM is very doubtful, since it has excess power for this. Whereas xDSD Gryphon is ideal for such purposes.

In general, I will say this, if you need a sound source that can cope with a wide range of headphones, including even planar full-size models, and for all its portability can be a good replacement for a stationary system, then you probably won't find a better iDSD Diablo. And if you need portability in a more compact size, with a flexible use case and the ability to work with both sensitive in-ear IEMs and high-impedance full-size headphones (we do not take planar models into account, here you need to look towards the older brother - Diablo), then the choice Gryphon would be the best solution in my opinion. Well, do not forget that there is still the possibility of receiving a digital signal over the air (Bluetooth), which is perfectly implemented, which the older brother does not have.

Ok Ok, let's go back directly to the description of the sound of our hero, otherwise I got carried away a little by comparisons.



The sound of the xDSD Gryphon is thoroughbred, smooth and clean, with a bodily filling of sound images. The device has a wide dynamic range, excellent speed characteristics, excellent tonal balance and amazing musicality. This is a living layer of sound, in which a plastic, neutral, well-balanced manner and refined melody coexist harmoniously.

Frequency amplitude

The low-frequency range is worked out precisely and bitingly, striking the ear with a clear pop and a tight, powerful blow. The bass is fast, prominent, dense and well-assembled, maintains the atmosphere with its dynamic manner, keeps the rhythm clearly and fills the middle with a dense velvety substance. The drums are extremely accurate, like artillery volleys, shoot their blows, scattering on both sides of the listener, and the parts of the bass guitar, cellos and double bass are transmitted unusually deep, lively and dynamically. The strength of each individual blow is clearly discernible. The register is transmitted cheerfully and harmoniously, powerfully and with the proper pressure!

Mids are distinct, smooth, natural, rich in timbre and texture. Here, every musical instrument and audio image is conveyed accurately and vividly. It is a well-balanced, pliable and multidimensional picture, with striking contrast and wide dynamic range, where every sound or instrument and every note played is clearly in its place in space. Stringed instruments, pipes and pianos - everything sounds pure, noble and harmonious. Male and female voices are displayed in relief, dense and naturalistic. There are no bright peaks or dips, everything is clear and to the point. This is a neutral, unusually dynamic, melodious, detailed and at the same time comfortable manner, presented in a melodic form.

High frequencies cleanly and clearly work out their own, correctly adding gloss and charm to the listening compositions. There are not many and not a few of them, just as much as needed. They are moderately restrained, there is not the slightest hint of friability or distortion in them. Everything is as honest, accurate and natural as possible. xDSD Gryphon transmits this register extremely competently, gracefully and multifaceted, smooth and informative, with good articulation, which completes the overall frequency harmony. Qualitative development of this range and nothing more. How I like it!


In terms of preference for musical genres, no weak points were found in the iFi xDSD Gryphon. He perfectly copes with everything: classical music, instrumental, jazz, electronics, old school rock and all kinds of brutal music styles.

Signal transmission via Bluetooth protocol.
When switching to a wireless connection, the sound of the device remains at a sufficiently high level, which is truly surprising. This is still the same manner as through the wires, but a little denser, with a little warmth and a greater depiction of the depth of the imaginary space.
Yes, the audio canvas loses a little in the transmission of micro-contrast, but at the same time it adds plasticity in relief, giving audio images more convex, and in general it becomes more musical. An amazing result. To be honest, I have never heard such sound quality when using various devices via Bluetooth. Although, it would seem, only recently I was very surprised by the capabilities of the iFi Go Blu baby, which I am not parting with now, but here the iFi engineers went further, making the sound even more serious.



xDSD Gryphon is, without exaggeration, an amazing machine! Everything is perfect in it: from design, implementation of the technical part, to the main thing - sound. It is a completely complete device in all respects, harmonious and balanced in everything. Without a doubt, the xDSD Gryphon will become one of the most revered and beloved portable tsapoi among audiophiles and music lovers.
I warn you that very loud words will be heard further, but this is my fully balanced opinion. So, I believe that at the moment in the world you can hardly find something better, given such functionality, sound quality and price. Although, of course, don't forget about the excellent Diablo! But here, when choosing, you need to proceed from the needs and scenario of using the devices.

At the time of writing, the MSRP for the iFi xDSD Gryphon was $599. Without a shadow of a doubt, I highly recommend this portable audio combine for your purchase.

You asked the question, "I have a portable amp that I may combine with xCAN, the small portable amplifier. Is the amp in xCAN performing as well as the amp in xDSD Gryphon?" I answered you. Perhaps I misunderstood you?
I am confused about your answer. Can you answer clearly if the amp in xCAN sounds better, worse, or the same as the amp in xDSD Gryphon?
Gryphon sounds better
