iBasso

iBasso Audio's Amp12 is now released as an ultimate separate amplifier module for their flagship DX320 music player, its large, dual batteries ensuring iBasso could take this module's analog circuit to town. Clean, precise and infinitely detailed, with plenty of headstage, air and also a rumbling, authoritative bass, Amp12 is a product of the comprehensive discrete circuit built within, one Headfonia says "enhances the player signature in many ways, giving you a more natural approach to the sound", complete with pictures. [See Product Desc. For More] Indeed, iBasso built Amp12 to act as a most faithful conduit to your music, allowing it to remain truthful to the way it was recorded. The voltage gain stage is tuned to provide a vast and open soundstage, while the power stage takes that and preserves all the low-end authority in your music. Headfonics throws this back to when iBasso championed the term neutral, in days gone by, Audio-PH talking about its perfect balance. Audiophile Heaven adds Amp12 gave music a new lease of life. Plug any big can from Sennheiser or ZMF Headphones straight in to be immediately impressed, or use its dedicated hardware line-out as the ultimate source for Cayin Audio's C9.

Nutubes return to iBasso Audio, bigger and better through Amp13 for DX300 and DX320. The size and power supply afforded by their flagship music players allowed iBasso to take this tube design to new heights. That extra circuit board space has allowed Korg's sixth-generation Nutube direct-heated triode to achieve new levels of signal-to-noise ratio, transparency and output power. Still Headfonics say Amp13 does all the above while offering the liquidity tube lovers desire with an even-harmonic character through single-ended operation. Musicality won out for Audio-Ph. Upgrading to iBasso's mature Nutube tech was totally worth it to Audiophile-Heaven. [See Product Desc. For More] Placed on Amp13's voltage gain stage where it will yield the biggest sonic difference, this Nutube's small output then gets boosted by a Toshiba FET buffer. This preserves square law at its input, such that it gets enough juice to drive the rest of DX320's solid-state output stage.  READ ALSO DAPs have gone down the tube iBasso built Amp13 with dual 3.5mm outputs. The hybrid Nutube section directly feeds Amp13's low noise, low output port (2.5Vrms) for sensitive IEMs. Meanwhile, an intermediary solid-state driver stage gets added for the high output port (4.1Vrms) to push Focals and Fostexs needing more gain. DX320's dynamic range spec is maintained through NJR's NJU72315 digitally-controlled analog volume part, and iBasso hide yet another trick up their sleeve: forcibly driving the ground signal of Amp13 to increase output power and reduce noise. The separate 2,000mAh analog battery aboard the DX3XX line supplies the backbone of power for Amp13's high operating voltages, with four clean, individual DC power sections for crucial parts of the module. The anode packs 21 volts of supply, while eight volt output rails continue to maintain excellent open-loop linearity before negative feedback. Such is expected of a high-performance iBasso Amp13 module that yields excellent distortion and noise specifications, while capturing the romance of tubes in DX320.

iBasso Audio didn't just add a 3.5mm output to its classic 4.4mm discrete Amp8, MKII also injects some DX320 magic straight into the DX240 music player. Twister6 thinks this completes iBasso's mainstay with a "resolving dynamic sound". Headfonia says it adds to DX240's flagship feel.  Audio-PH believes the ease of the Amp8 MKII upgrade was "to embody your skills and demonstrate them to a large audience", and MOONSTAR Reviews definitely seconds the added variety and sound quality. [See Product Desc. For More] Based off the stock Amp11 MKII of DX300, a high 8 volt operating voltage grants AMP8 MKII excellent open-loop linearity, with the ability to effortlessly reproduce large dynamic swings in your music.  That's all backed by discrete buffers capable of 2 amperes output to form a potent power stage, able to maintain excellent drive into the ever decreasing impedances that are typical of bone conduction or electrostatic IEM hybrids.  Add Amp8 MKII to your DX240 for a controlled sub-bass boost and detailed emphasis in your upper midrange, while giving your big, transparent, Craft Ears and Empire Ears flagships the footing necessary for them to show everything they can do.  Also browse the rest of iBasso's line-up here, or our other music players here.

ESS Technology DAC chips debut here in an iBasso Audio USB-C DAC/amp dongle, and boy does it show in the way the 3.5mm DC05 sounds. Plenty more involvement and detail shows in the way this dual ES9219C dongle that plays Tidal MQA sounds, reminiscent in more ways than one of the flagship DX240 music player. Headfonia consider DC05 a "very serious option", and Headfonics add it has everything for a 3.5mm DAC/amp. This iBasso made its way into Audiophile-Heaven's Hall of Fame. To turn your Android, iPad or other mobile device into something mimicking iBasso's reference DAP is no mean feat, but hearing is believing. Enjoy lots of involvement through the mid-range in particular where the majority of your music lies, though that doesn't detract from plenty of presence still in the lows and highs.  Drive your favourite earphones and headphones alike through DC05, or browse iBasso's other offerings here and our other DAC/amps here.

The mobile revolution continues as driven by iBasso Audio. DC06 is their latest balanced 4.4mm dongle supplied by dual ESS Technology ES9219C DAC chips, with analog volume control aboard. iBasso claim 123dB of signal-to-noise ratio as a result, for music player levels of detail and fidelity even from USB's 5 volt supply. It's solutions like DC06 that continue to see USB DAC/amps raise their game. Headfonia praise DC06 as "something really catchy ... a possible must-have". Headfonics confirm it does it all. Audiophile-Heaven recommend it for "a super natural, clean sound with excellent staging and instrument separation". [See Product Desc. For More] Further pushing decoding precision is an outboard clock that means DC06 does not rely solely on its USB receiving chip for a master clock. iBasso derive a clean clock signal via PLL, pushing down phase noise and reducing jitter even at this form factor. DC06 also decodes 16X MQA, to boot. Pure, clean analog is therefore derived from your mobile sources, and this pristine little dongle DAC isn't afraid to push big cans either – promising up to 320 milliwatts from its 4.4mm output. The DC06 platform comes with a detachable cable and can be adapted for a range of mobile applications, from smartphones to iOS Lightning and laptops.

Returning to the market that DX160 defined, iBasso Audio give you its successor DX170. This condensed, rocket-powered Android 11 music player gives you a huge helping of the high-end, and appeals to all levels of music lovers. Whether you're just starting out exploring what 2022 brings in terms of portable digital audio, or an experienced aficionado looking for something light and small to carry portably, iBasso has your backs with its streaming, 8X MQA-ready DX170. It went onto Audiophile-Heaven's Hall of Fame, and Ear Fidelity's Highly Recommended list. ichos Audio had nothing meaningful to criticise. Dual Cirrus Logic CS43131 DACs provide the decoding backbone for DX170. iBasso have bolstered the performance of these popular chips with a FPGA-controlled clock and data master. [See Product Desc. For More] This FPGA sees DX170 overachieve by supplying its CS43131s the same pure I2S as iBasso's bigger DX240 and DX320 siblings, pushing down DAC phase noise and jitter for a stable decode. After decoding, iBasso's generous use of negative feedback quashes distortion and claims up to 130dB of signal-to-noise ratio. The employment of this feedback also sees DX170 achieve massive bandwidth that's effectively flat 10Hz to 40Khz. That means phase reproduction in the audible human hearing region is stellar, for realistic reproduction of dynamics and natural transparency – a triumph of iBasso's entry-level music player. The quality of DX170's signal will translate to nearly everything you choose to drive from its balanced 4.4mm output, or 3.5mm. Powerful output buffers supply current and mean iBasso's wonderkid promises high damping factor while maintaining its low distortion into low impedances typical of IEMs, Focals, Fostexs and Rosson Audio Designs. Still the closed-loop internal gain remaining after the application of negative feedback around DX170's op-amp IC analog circuit remains high. So where she really shines is in swinging voltage, opening up the sound of any high-impedance Audio-Technica, Sennheiser and ZMF Headphones while barely breaking sweat. On the go, DX170 will see you retain so much of what defines iBasso's reference DAPs. You'll want to get your music aboard via your favourite streaming apps. And their future-proof Android 11 software will mean Google Play Store app support of Tidal, Spotify and Apple Music for years to come. Backed by a SOC processor that has posted AnTuTu scores in excess of 100,000, that's one more sign of smooth daily operation ensuring you'll never part from your DX170. That is, unless you move up to one of iBasso's bigger reference cousin's here, or one of our other music players here...

iBasso Audio have shown Head-Fi what the entry-level DX170 and flagship DX320 are capable of. And it's been left to the DX240 to act as the crossroads of them all, bringing together all the best traits of iBasso's DAP prowess into one single device.  DX240 is so good, in fact, it displaces DX300 on Headfonia's Recommended Buy list and joined its big sibling there on Audiophile-Heaven. DX240's owners are entitled to three free amp card endplates and a matching leather case worth $149, while the upgrade to Amp8 MKII updates capabilities further! [See Product Desc. For More] Revitalising the popular form factor that the original genre-defining DX200 and DX220 packed, the DX240 is another cumulation of the progress iBasso have made. With stock Amp1 MKIII, this versatile player promises an abundance of transparency and plenty of involvement through a liquid mid-range, particularly with female vocals. ESS Technology's ES9038Pro top-dog – outputting in current to a proper I/V stage for best distortion characteristics – arrives as the decoding backbone. The refinements made around this DAC chip bring DX240 into portable audio's future.  Trickling down from the DX320, a FPGA acts as a clock and data master, presenting raw I2S for the ES9038Pro in the cleanest, quietest and most precise manner. Joining those are the Snapdragon 660 CPU, along with 4GB of RAM and 64GB of storage.  Headfonics say DX240 lands with real purpose in the world of modern music players. Major HiFi met "really no setbacks to this device whatsoever". MOONSTAR Reviews says DX240 delivers sonically, and in terms of usability. "Every dollar works out completely" to Audio-PH.  Twister6 found this iBasso a jack of all trades and master of them all too. Full Google Play Services and Android 9 usability is a breeze when viewed through DX240's 1080p screen. Play up to DSD512, 16X Tidal MQA and full Hi-Res Lossless Apple Music online or offline – entirely bit-perfect through iBasso's bypass of Android sample-rate conversion. Truly, DX320 miniaturised desktop DAC/amps – and DX240 miniaturised DX320. With a palm-and-pocket-friendly form factor, DX240 is reminiscent of DX170 – but with added amp card modules. Amps1 through 8, developed for iBasso's DX2xx line, are compatible here, so your collection of cards will find a new lease of life. At the same time, enjoy the new Amp8 MKII, developed for and only for the DX240. But really, iBasso's DX240 is a new lease of life for the entire music player category, balancing fidelity, power, portability and access in one stroke. Bravo – also shop iBasso's other releases here, or all our other music players here.

DX320 exploits every ethos of iBasso Audio's flagship series to reach the zenith of DAP development. The Android 11 DX320 makes full use of its massive power supply and circuit board real-estate for an extreme discrete analog circuit, to give two new ROHM BD34301EKV DAC chips the platform to perform. iBasso's latest and greatest rewards those who don't look only for the obvious – those who appreciate that a wonderful music player starts with its DAC chips but arrives at the finish line with their implementation. The long-awaited successor to the ever-popular DX300 pays tribute to its predecessor, pushing boundaries in the same spirit. Yet it very much touts its own identity, packing a deep bass that is commanding, and dynamics that are resolute. It starred for being "deeply engaging" on Headfonics. Headfonia elected it straight onto their Recommended Buys list. Twister6 thinks it's one-of-a-kind for ticking so many boxes. DX320 "has everything to conquer even the most demanding audiophile" for Audio-Ph, which put it on Audiophile-Heaven's Hall of Fame. [See Product Desc. For More] iBasso's newest spawn is proudly liquid and coloured – accurate yet veering from sterility. Sweetly indulgent, like an information-rich fruit cake of a DAP. Soundstage spans forward and spherically for deep immersion and involvement, so the whole musical experience feels unified by a connective tissue. "What really stands out about this true high-end player are its excellent technical sound performance and its very natural overall presentation" to MOONSTAR Reviews. DX320 trades up its digital decoding backbone to a pair of the well-received BD34301EKV.  An in-house designed FPGA acting as a clock and data-marshaling master supplies pristine I2S to the DACs, which then oversample and decode at a 16X internal rate for peak Nyquist performance and shallow ROHM linear-phase digital filters to be employed.  Crucially, DX320's BD34301EKVs output analog in current, as demanded by a DAP that claims to be of flagship status. iBasso are therefore afforded the opportunity to tailor the DAP's sonic profile as they wish with a current-to-voltage I/V converter, and the added measure of ensuring that small-signal is of the lowest distortion to begin with. Volume is controlled via a proprietary iBasso solution, specially developed for these ROHM DACs. So begins DX320's fully-balanced, true differential analog circuit that runs at a massive 8 volt operating voltage for linear open-loop operation. Its power stage is fully discrete and boasts buffers capable of putting out 2 amperes of current. DX320's bridge-tied load operation halves impedance per output phase, but the potent output transistors comprising the power stage mean it's never fazed driving low impedances. Happily use DX320 with anything ranging from the 3ohm Empire Ears Odin, up to the 300ohm ZMF Headphones Atrium on stock Amp11 module, or switch out the modular analog card for the yet-more potent Amp12 or tube Amp13. With 2.5mm and 4.4mm balanced outputs removing need for cheaply-built, signal degrading adapters for connections to make something fit, your flagships can be juiced to the max potential, signal integrity guaranteed via direct sockets soldered to PCB. The quantity of output power has been discussed, but the quality's not yet mentioned. DX320's total 6,000mAh power supply component is split into a 4,000mAh battery for the digital sub-system, and separate 2,000mAh unit for the afore-mentioned analog circuit. Doing so cleans up the lifeblood for clean, quiet audio available system-wide, iBasso touting their custom-made bypass capacitors as a DC filter for purer power yet.  All the above would mean little if DX320 wasn't built with the future of music consumption in mind. But thankfully Android 11 makes its appearance to be at the cutting-edge of DAP UI, processed by the speedy Snapdragon 660 SOC plus 6GB of RAM for smooth operation.  16X Tidal MQA and Apple Music will be streamed at bit-perfect level via Direct Transport Authority (DTA), bypassing otherwise mandatory and detrimental Android re-sampling. DX320 was the complete package to Major HiFi and deservedly took their Gold Award. Thus is DX320 – iBasso's most complete and most advanced line music player – released, designed to tackle every one of the modern audiophile's needs.

A flagship worthy of iBasso Audio's 10th anniversary manufacturing DAPs, and 16 years as a pillar of personal audio. DX320 gets reborn in the form of the limited-edition DX320X, its chassis machined from titanium-based liquid metal alloy. An actual patented design of soft lines and intersecting curves, an excruciating machining process of the superbly hard and durable liquid metal yielded 500 pieces globally at great cost. Making DX320X yet more prestigious are the fascinating electrical properties of its titanium liquid metal chassis. Acting as the device's ground, this intriguing material is inadvertently bound to colour the sound of DX320 – already a Head-Fi favourite.  With X exquisitely liquid in the highs, packing a deep sense of inner resolution, composure and confidence in making out music, owners will thus not only be able to count on the flagship sound quality of a DX320, but one unique unto itself even in the realm of iBasso players. [See Product Desc.

The countdown began with the IT01 leading iBasso Audio to release this entry-level king's successor, the IT00. Headfonia highlights this dynamic driver IEM's "mellower signature and better vocals" in comparison to its predecessor. [See Product Desc. For More] Its spotless feel clothed in white prepares you for an uber-clean sound you'd normally expect of a statement price tag. That's ensured by IT00's overachieving thin graphene driver, Helmholtz resonator and a high magnetic flux of nearly one tesla. Major HiFi found themselves asking "why you would need anything more than this". Prime Audio Review says IT00 "has bass to die for, a full-bodied, clear midrange and a lively but sweet treble", putting it straight on his Best IEM list. Audio-PH adds that iBasso "held a practical master class for us and showed that they can design a cool thing in any price segment". This is a great pick to begin with on your audiophile route. Twister6 loved turning these into an instantly gratifying pair of audiophile true wireless buds with iBasso's CF01 Bluetooth adapter.  Both join the rest of iBasso's hits here, while you can also browse our other earphones here.

Beryllium and brass make IT01X another sure iBasso Audio buy. Premium materials make this single dynamic earphone another standout over-achiever after IT00, ready to rack up more plaudits from the Head-Fi world. A single dynamic driver appears enough to achieve the highest resolution possible. In this case, iBasso have helped this entry IT01X all the way, employing a beryllium-plated dynamic driver chambered in a brass inner cavity. [See Product Desc. For More] You'll know the moment you pick it up that iBasso engineered this for sonic honesty and transparency, to hear deeper within any mix. A sandwich driver has its surface coated with beryllium for the metal's stiffness, lightness and air acceleration properties. IT01X's driver material combination helps it move as a perfect piston over all frequencies up to and above its working range, keeping distortion down due to cone and modal break-up as frequencies rise. Low frequencies emerge with authority thanks to the brass chamber built into IT01X's compact and truly ergonomic shell, Helmholtz resonators stimulating proper airflow and reducing standing waves in the bass. The driver responds lightning quick due to a high-magnetic flux produced by a strong neodymium magnet, completing a package iBasso masterfully engineered at any price. IT01X promises high-resolution playback without the premium. Twister6 say it ticks the boxes anyone would want in an affordable reference. It touches Audiophile-Heaven the right way. MOONSTAR Reviews praise IT01X's "strong bass performance, highly transparent and silky smooth midrange, and with a treble region that is able to produce a great sense of airiness and sparkle". Ladies and gentlemen will put on the featherweight, easy-fitting shell for hours on end, lost in their music. You can also compare IT01X to its multi-coloured IT00 sibling here, check out everything else from iBasso here, or view our other IEMs here.

A correct, reference tuning need not be boring, as proven by iBasso's IT04. This four-driver hybrid IEM begs to be played track after track.

iBasso Audio releasing a flagship UIEM is exciting, and certainly tuned for excitement is the brand-new IT07.  This seven-driver hybrid puts top quality components at your service, as a graphene dynamic driver for bass props up six premium Knowles balanced armatures. [See Product Desc. For More] IT07 proves its worth at the bottom and at the top of the spectrum, thrilling with its bass and treble performance. There's the option to dial these in further yet, with included interchangeable acoustic filters within reach to suit multiple sources, tastes and music genres. Tasteful emphasis of the frequency extremes flank a lucid and spacious mid-range performance that flows effortlessly, its liquidity reminiscent of AM05. Emotive vocals never risk being overshadowed.  Audio123 sees this as a legitimate step up from iBasso's previous IT04 in a comparison with today's popular flagship UIEMs. Headfonics has "no complaints because it does so many things very well ... Tesla driver can dig deep into the bass, the vocals sound very smooth and clear and the highs are clean and crisp with an overall balanced frequency response". MOONSTAR Reviews and Twister6 compare it favouribly with other flagships of its day, with IT07 holding its own against Meze's Rai Penta and 64 Audio's tia Trió, among the rest. An excellent stock cable terminated in balanced 2.5mm comes included, to work from the box with iBasso's DC01 USB-C DAC dongle, or one of our music players here.  // RECOMMENDED: Upgrade with the IBASSO CB16 if you're part of the 4.4mm club.

iBasso Audio's Year 2020 contribution to Head-Fi involves a high definition, open back rendition of a monitoring sound. Two years of research after its predecessor, the SR-1 allowed study of strength to be distilled in the SR-2. A full open-back deploying Tesla magnetic flux technology with bio-cellulose dome diaphragms, iBasso's SR2 promises a wider soundstage and transparency that may lift elements waiting to be discovered in your music.  Package comes with a second pair of stock pads that add tuning ability shifting the SR-2's natural presentation to a tighter, tauter and faster one. Major HiFi wrote "things are looking up when I'm still thinking about how some tracks that I haven't tried might sound on the SR2". Audiophile Heaven wholeheartedly recommend SR2 "if you're looking for a comfortable, light, and well-made headphone, with a natural tonality, rich sound, with a natural soundstage, and with an excellent amount of detail for the price".
