iBasso Audio
iBasso Audio is a boutique audio manufacturer from China famous for their premium digital audio players (DAPs), like the DX340, and portable DAC/amps like the DC07PRO. The brand has lately expanded their catalogue to include desktop audio components, the Kunlun is a powerful headphone amplifier that marks the premier in this category.
Many people tend to forget that iBasso also produces a wide range of high quality earphones, covering everything from entry-level options to more expensive ones, all while maintaining the brand’s well known “value for money” philosophy. Notable examples are the flagship IT07, the mid-range 3T-154 and the entry-level KLEE.
iBasso Epitome
iBasso’s most expensive earphone till now was the $899 IT07, so it came as a big surprise when they announced their new flagship model, the Epitome. An ultra high-end earphone that took more than 5 years to develop and costs an eye watering $3499.
The Epitome is a multi-driver earphone that features no less than 20 drivers per side (8 EST + 12 BA), blending EST airiness with BA precision across the entire frequency range.
Technical Specifications & Features
More specifically inside each shell 4 dual EST drivers are used for the 10Hz-20kHz range, 1 dual high frequency Knowles BA driver for 6kHz-12kHz, 2 dual Sonion mid-high BA Drivers for 3kHz-6kHz, 2 dual Sonion mid BA Drivers for 400Hz-3kHz and 1 dual Sonion low frequency BA driver for 20Hz-400Hz. That is 8x Sonion EST + 10x Sonion BA + 2x Knowles BA.
All these drivers are supported by a complex 5-way crossover designed with premium through-hole components, made to deliver smooth transitions, unified tonality and excellent integration of the driver groups.
Design and Wearing comfort
The iBasso Epitome shells are 3D-printed from hypoallergenic medical-grade resin and designed with smooth curves that form a custom-like shape after the natural anatomy of the ear.
Given the driver count, someone would have expected very bulky and weighty shells, however the Epitome is not that bigger or heavier (6g each) than most other multi-driver earphones, like the LETSHUOER Cadenza 12.
The shells are large, no doubt about that, but they don’t protrude too much outside the ear and they actually fit comfortably and strain free, at least for people without too small ears. I can use the Epitome for a few hours continuously without the need to take a break.
The metallic nozzles are of medium length so they help to achieve a stable and secure, yet not too deep fit. They have a stem that holds the ear tips securely at place but they lack an ear wax protective mesh. The five sound tubes are directly exposed and might need regular cleaning with a specialized tool before they become completely clogged by wax and debris. Another solution is to use ear tips with wax guards.
Outer Appearance and Build Quality
Going against the current trend that wants most flagship earphones to come with fancily designed (and sometimes kitsch) faceplates, the Epitome follows a much more classic and minimalistic approach.
The unified shells are printed with a technique that embeds three-dimensional powder patterns inside the resin compound that exhibit various gradient flickering effects and colors under different lighting angles. The “EPITOME” logo is engraved with silver letters at the top of each shell, adding the finishing touch to this plain, yet elegant and visually attractive design.
The iBasso Epitome is made with the highest quality standards, it looks and feels exceptionally premium but without screaming “hey look at me, I am a flagship earphone”. Modesty is the governing philosophy behind both the design and the tuning concept of the Epitome.
At this point it should be noted that it is very difficult to photograph the Epitome and it actually looks much more impressive in real life than in any photo, especially the low quality ones that I hardly managed to shoot.
Accessories
The earphones come packed inside a classy wooden box that is wrapped with stitched black leather and includes a lot of high quality accessories.
Open the lid and you will be greeted by a rounded metal storage box, a yellow leather carrying case with a magnetic lid, six types of ear tips in three sizes each and two premium cables.
Unfortunately, both cases are not big enough, especially the rounded one, so they can marginally accommodate the Epitome with its cable but there is no room left for a USB DAC.
The Epitome is equipped with just the right amount of premium accessories and nothing else unnecessary that could raise the final cost without being useful. The only thing missing is one of those plastic trays that are used to sort and store the ear tips.
Two High Quality Cables
The stock cable is made from 5N mono-crystal copper in a Litz structure with two woven strands per channel and is reinforced with a black plastic sheathing. The cable is equipped with interchangeable plugs (3.5mm, 4.4mm and USB type-C plugs are included in the package) and 2-pin connectors on the earphones side. It is a thin cable that is lightweight and soft, with minimal microphonic noise but it gets easily tangled.
iBasso has recently developed a more premium cable with a newly researched silver-plated copper alloy, that is included as a gift since it is not yet fully tested and in its final form.
This is a thicker Litz cable with three woven strands per channel and a more durable fabric outer sheathing. It comes with a fixed 4.4mm plug and higher quality hardware parts than the stock cable but it is heavier and has terrible friction noise. This is something that iBasso should work to solve before the commercial release of this otherwise excellent cable.
One last thing to note is that the shells of the iBasso Epitome are designed with flush 2-pin sockets, but both cables come with plugs made for recessed sockets. Really nitpicking here but at this price point every detail counts.
The Lavricables Grand Upgrade Cable
Cable believer or not, the iBasso Epitome responds very well to cable changes and this is why iBasso has supplied two cables instead of one. The stock has a warmer sonic signature and offers fuller textures while the second one enhances resolution and technical precision, also adding some extra sparkle and brilliance in the treble.
After experimenting with various aftermarket cables, I ended up using the Lavricables Grand that sounded much more complete than anything else I had at my disposal, including other options by Lavricables.
Tons of resolution, surgical technical precision, class-leading transparency and the most weighty textures without lacking in definition and clarity. The Grand doesn’t alter the frequency response of the Epitome or add any sonic character of its own but it just lets the music flow. Excellent sonic coherency, massive soundstage and wide dynamic range from a cable that makes full justice to the Epitome, however it should be noted that it is heavier and thicker than the average earphone cable.
Efficiency and Source matching
With a lowish 17Ω impedance and high 113dB SPL/mW sensitivity, the Epitome is ridiculously easy to drive but also extremely sensitive to background noise. Power is not an issue, you can drive the Epitome from any source out there but it must be as silent as possible to make sure that noise is either absent or so low that is not audible during music listening.
Using premium sources is also mandatory because the Epitome scales practically without limits and demands only the “crème de la crème”, like the iBasso DX340, the iBasso D17 and the Cayin N6iii that I have mostly used. They are expensive, but honestly speaking , I can’t imagine someone spending $3.5K to buy the Epitome without having correspondingly high-end electronic components to pair it with.
Listening evaluation
Unlike most flagship earphones that are tuned after the Harman target curve or one of its hundred commercial variants, the Epitome follows a radically different path. iBasso decided to break new ground by adopting a reference-style and very mature tuning concept that is not strictly neutral or flat but balanced and natural.
iBasso engineers handpicked all drivers and managed a masterful integration with the aid of the sophisticated crossover. The Epitome is especially cohesive and doesn’t compress at any part of the frequency range. It doesn’t distort, even at deafening volume levels, so be careful as you can easily get carried away and start listening dangerously loud without even noticing.
The Tuning Concept
It seems that the goal behind the sophisticated voicing the Epitome was to make an earphone that could reproduce singers and the instruments of the symphony orchestra, from the lower to the higher pitched ones, with the most accurate tonal precision and as close to reality as possible. Rumours are that iBasso engineers spent so many hours doing fine-tuning and exhaustive comparisons that in the end, some of them gave up their hands and started screaming “I can’t do it anymore”. Fortunately, the right combination was already found and the Epitome reached its final form.
The Epitome doesn’t sound like regular earphones, not even headphones, the sonic presentation resembles high-end speaker systems or even better the actual listening experience inside a concert hall.
From the lowest octave to the highest frequencies, the tuning is even and coherent throughout. Each frequency band carries just the right amount of sound pressure, allowing instruments and voices to be reproduced faithfully at their correct pitch, while also preserving the actual tonal balance of the recording.
The Epitome is not a flagship earphone that tries to sound spectacular and impressive by imposing its own personality and subjective interpretation of the music. What it does is to place every sound element at the right spot, as accurately as possible, and not at its own will. It is so transparent and uncolored that what you are actually hearing is pure flowing music, the truth and only the truth as dictated by the recording and the source alone.
The low-end
The sub-bass is deep enough to ground the music and reproduce the lowest frequencies without overpowering the rest. Think of it as a well calibrated subwoofer that solidifies the low-bass while vanishing from the room so you can’t tell if it is playing apart from the main speakers.
The bass is neutral but not strictly flat, with a tuning that lets each instrument resonate naturally, combining tonal precision with a pleasing sense of warmth, weight and body. The BA units that are assigned to the lower frequencies can easily compete with some of the best dynamic drivers. They don’t lack much physical impact and raw power, while they present the bass with unexpectedly visceral textures and natural decay for BA drivers, avoiding to sound thin or dry as it usually happens.
These BA drivers might not be as grand sounding and imposing as large dynamic drivers but they easily outperform them in technical performance. The bass is crystal clear, fast, ultra tight and controlled with the right timing and class-leading definition. It is really impressive how iBasso has managed to pull out such high quality and technically skilful bass that is also not that lacking in its physical characteristics. The Epitome can handle the most demanding and complex bass lines without breaking a sweat, and still sound weighty, full bodied and elastic.
While the low-end of the Epitome is tuned after reference precision and primarily made for critical listening, you can also enjoy it more casually. Especially if you use narrower bore and thicker sided ear tips that raise the bass amplitude up to a certain amount and make it much more enjoyable and a fun listen with mainstream music.
The Mid-range
Free from any mid-bass bloat or lower frequency masking, the mid-range emerges with a clean and present profile, evenly tuned and tonally balanced. The Epitome stands out for its melodic fluency and deep expressiveness, it is an earphone that captures the full harmonic wealth of the music and sounds naturally organic with the right source combination.
The timbre is realistic and convincing, allowing mid-range overtones and harmonics to sound lifelike and alive. The Epitome’s class-leading resolution and texture refinement add further to the overall sense of realism, leading to a holistic and sentimentality engaging listening experience.
The High frequencies
The treble is the area when you can truly understand and appreciate all the dedication behind the Epitome’s tuning. Unlike other flagship earphones that rely on artificially boosted brilliance and other tuning tricks to make their presence known and sound spectacular at the beginning, but usually fatiguing and fake on the long run, the Epitome seduces with its low-profile maturity.
We must understand at last, that resolution should not always be confused with enforced detail retrieval and over-analysis of the music. The Epitome offers great amounts of resolution but it never sounds sterile or monotonously analytical. It rather lets the listener decide whether he is going to dive deeper inside the recording and explore every last hidden corner, or just sit back and relax without focusing too much on the details. Resolution here serves the music by adding extra layers of depth and realism rather than promoting monitoring accuracy.
The treble is smooth and polite yet very extended, luminous, airy and energetic without any audible metallic sharpness, artificiality or excessive brightness. The EST drivers produce ethereal and refined but not fragile textures. The notes have actual substance, they decay quickly enough but not too fast, so the Epitome can easily follow fast paced music without make it sound as lacking in mass and weight.
The Soundstage
The soundstage stands out as one of the Epitome’s most impressive advantages over the competition. Generously wide and open, but not artificially stretched, it is so good that it competes with open-back headphones rather than earphones. Spacious and airy with especially accurate imaging and excellent depth layering, it easily adapts to the scale of the music and always sounds natural and immersive, be it playing a small sized ensemble or the full symphony orchestra.
It is spectacular in its presentation, not only for its grand scale and the precise placement of every sound element within the stage, but also for the direct communication of the surrounding atmosphere in the most holographic way. The listener feels like sitting midway from the performers and the music stretches well out of the head and ears in a way that resembles nearfield speakers.
Rolling Ear Tips
The Epitome might not have tuning switches or interchangeable sound tubes but it is fairly easy to fine-tune it by using various ear tips as it responds better in this regard than the average earphone, allowing more meaningful sonic adjustments. The package includes six types of ear tips, each one offering a slightly different sonic profile without altering the base sound character of the Epitome.
Generally speaking, narrower bore ear tips tend to boost the bass while wider boar tips are used to enhance portions of the upper mid-range and treble. Thicker tips add more weight to the low-end while thinner tips tend to make it sound leaner and drier. The wider the ear tips, the more you get out of the Epitome’s transparency, grand soundstage, tonal balance and natural sound flow. For users that are after these qualities, I strongly suggest trying the Divinus Velvet Wide Bore ear tips that are my favourite with the Epitome.
The Epitome Vs the LETSHUOER Cadenza 12
The only other flagship earphone in my possession that can compete with the iBasso Epitome is the LETSHUOER Cadenza 12 that sells for $1999. Not a fair comparison though because the Epitome has much more drivers per side and is $1500 more expensive than the Cadenza 12.
The Cadenza 12 is slightly bigger and heavier (10g each) than the Epitome, despite the lesser driver count, and doesn’t feel as comfortable. However it is made from titanium alloy, a material that is more durable and some users might prefer its feeling to the resin compound.
The tuning of the Cadenza 12 is mainstream but not too V-shaped, however it is not as neutral, tonally balanced and transparent as the Epitome. Its overall presentation is warmer and ticker with added bass presence in comparison to the Epitome. It is an earphone that is funnier to listen to with modern tunes and its bass sounds more impressive and impactful but it lacks the precision and the technicalities of the Epitome.
The Cadenza is a flagship earphone made for casual listening without excluding more critical applications, whether the Epitome is the opposite: ideal for reference/critical use without excluding casual moments. However, what the Cadenza 12 can’t even remotely touch, is Epitome’s natural music flow, the ethereal and refined textures, the absolute timbre realism and the impressively holographic and immersive soundstage.
In the end
The Epitome is a flagship earphone with an “unconventional” tuning by modern standards that pushes sonic realism to its upper limits, an earphone that lets the music flow with breathtaking purity rarely found in the competition. The iBasso Epitome is literally the “epitome” of music making, it is like an instrument at the hands of a skilled musician that creates art, drawing you deeper and deeper into the music.
