TANGZU XUANWU GATE: A Grandiose Neutrality

"With bronze as a mirror one can correct one's appearance; with history as a mirror, one can understand the rise and fall of a state; with good men as a mirror, one can distinguish right from wrong"

~~Li Shimin, also known as Emperor Taizong, Second emperor of Tang Dynasty.

Xuanwu Gate Incident was a pivotal moment of Tang Dynasty's history where a coup initiated by Li Shimin also known as Emperor Taizong, who was a prince back then, assassinated his elder brother, the heir apparent of the imperial throne and also his younger brother for bidding of its imperial power and also avenging its allegedly poisoning attempt by them. This event culminates the distant and cold relationship between Li Shimin and his father, Li Yuan, the first emperor of Tang dynasty even until the latter's death.

TANGZU products have their own significance in the audio market on which they named their product models from historical personalities during the Tang Dynasty era. But this time, the model name is based on a historical event that truly changed the destiny of the Tang rulership in ancient China.

TANGZU Xuanwu Gate is the latest product from TANGZU which is also their first flagship midrange line. It has hybrid driver configuration consisting of dynamic driver, balanced armature drivers and “Electrostatic(EST)/Electret” drivers. The dynamic driver that was used here has a dimension of 10mm and is made of carbon composite which is known for its flexibility and lightweight properties that will benefit the quality of the bass. The four (4) customised balanced armature drivers will handle the clarity and lucidity of midrange and highs, and then, the EST/Electret driver made by SONION will be responsible for the resolving, transparent and extension of ultra-high frequency. It also has an electronic frequency crossover for better separation while having a cohesive sonic performance.

The drivers were encased in a rather large modified UIEM-type shell chassis made of solid aerospace-grade aluminium alloy which are known for its less resonance properties with fatigue resistance and tensile strength. Its gold-plated faceplate looks pretty gorgeous and sophisticated with its terraces-like outlines that were inspired by rice terraces fields that are usually found in Asia. Even on its cavity base, it has those outlines to look even more élan and classy. Like most TANGZU sets, it uses a 0.78 bi-pin connector as its interlocking mechanism with its detachable cable.

Despite the large size of its shell chassis, it still fits well into my lugholes without any discomfort and ear fatigue as it rests well on it. It also offers a good passive noise isolation that is able to block some noises from the outside surroundings.

Flagship midrange sets should have a high quality stock cable and Xuanwu Gate has it. It has a premium thick stock cable which has a modular option where we can interchange its angled L-shaped termination plug in which we can choose either single-ended output or balanced output. It has an 8-core monocrystalline silver-plated copper which is known for its clear and lively sound (according to cable sound advocates).

As for product packaging, The product box of Xuanwu Gate is quite humongous and probably the largest IEM box that I've encountered so far and it also remarkably grandiose in terms of unboxing on how its contents inside are organised and well-presented.

Here are the following contents inside of Xuanwu Gate's box.

• Pair of TANGZU Xuanwu Gate IEM transducers.
• Stock cable
• 3.5mm single-ended termination plug adaptor.
• 4.4mm balanced termination plug adaptor.
• Carrying case
• Three (3) pairs of Sancai wide bore eartips in different standard sizes.
• Three (3) pairs of Sancai balanced bore eartips in different standard sizes.
• Paperwork like user's guide and warranty card.

In terms of power output and amplification, Xuanwu Gate can be driven by a device like a smartphone with normal gain output in a device but putting in better sources will surely give the  most satisfying output with its full range and vivid sound.

As for its tonality, This set has this balanced-neutral sound profile in which all parts of frequencies are evenly presented across its sound spectrum without too much emphasis of a certain specify frequency

LOWS/BASS:

In my ears, this is clearly a quite balanced bass as it has a rumbly and reverberating sub-bass presence and sufficiently textured mid-bass. Overall, it has an accurate, precise and rumbly bass response that make this set truly a midranger sound quality.

Sub bass-focused instruments like synthesisers, drum machines and low tone bass guitars have this perceivable deep reverberations and rumble sound generated from those instruments. Bass guitars have a resonant and rasping sound from fretting, slapping and fretless on its note strings. Bass kick drums have sustaining, thudding and resonant sound although sometimes it has lack of slam and authority that this instrument should have but it has quite fast that syncs well with fast double bass drumming from extreme metal tracks. Bass to bass-baritone vocals appear to have a less depth and lack of well-modulated gravelly sound to have that deep, full and dark tone that these particular male voices should have.

MIDRANGE:

Probably the strongest assets of this set on how the midrange presentation of this one has well-balanced, tidy, neutral and energetic sound that gives more lively and vividness on most vocal types on either male or female and instruments. It is also a slight warmth just to give ample note weight on male vocals and percussives.

On male vocals, it gives a smooth, adequately rich and plush sound on some baritones like light and lyric baritones but it sounds less steely, less fuller and a bit milder on kavalier baritones, verdi baritones and noble baritones. Tenors sound almost flawless on this set as it sounds brassy, dazzling and spicy that all tenor types sound very well and depicts its accurate tone on this one. For countertenors, they sound smooth, velvety and tender that makes them pleasant and lilting to listen to. As female vocals, contraltos have a lush and smoky sound from their voices but I wish that it has more depth on it. Mezzo-sopranos have these fiery, emotive and tender voices that makes them sound so insouciant and captivating while sopranos are well-presented here with is spacious, energetic and detail vocals as they sound quite gleaming and crystalline that coloratura-type of soprano can execute those complex, florid vocal passages.

On instruments, strings like guitars and violins, it sounds crisp, ceiling and bright on the former while a vibrant, lively and sweet sound of the latter instruments. As for woodwinds, it has clear and brilliant sound on piccolos, a bright, airy and silvery sound on concert flutes, a dramatic and expressive sound of clarinets and a sonorous and forceful sound of saxophones. Brasses like trumpets, trombones and horns, they sound intense, penetrating and ponderous respectively. On percussives, there's a resonant and ample warmth on tom-toms, a sharp and precise sound on snare drums, a majestic sound of field drums on every stroke of its drum head and a velvety yet resonant sound on kettledrums. The sound of the pianos are quite well-balanced with sufficient bright and ample warmth of its tone.

HIGHS/TREBLE:

The treble response of this one is mildly bright and a tad smooth sounding as it has slight yet correct emphasis on upper-mids up to the presence part of the treble region to give detail, definition and clarity on vocals and attack of instruments on either percussive and rhythmic ones. There is a noticeable slight dip somewhere between presence and brilliance treble as I didn't hear any sibilance and stridency on this set despite its tad shimmery sound. Although, I will still suggest that treble-sensitive folks should be aware of energetic tuning as it might be still sensitive to them.

It has a good sparkle and excellent treble air extension that make this set quite impressive for its own right. Cymbals have a lustrous and sizzling sound while hi-hats have a short buzzing sound from them. Celestas have a silvery and sweet sound, and glockenspiel have a bell-like and sheen sound on it.

SOUNDSTAGE, IMAGING & OTHER TECHNICALITIES:

Overall, the Xuanwu Gate has an excellent mark in all aspects of technical performance, it has a spacious proportion of its sound field within my headroom as it has a wide lateral span from left to right, good height reach and stage depth distance from front to rear. As for stereo imaging, it appears that it has a concave-like presentation rather than holographic that I usually encountered in most midrange sets that I've tested but I was able to locate the placement of instruments and vocals precisely in a well-layered soundscape and I can assure its remarkable separation. So playing the most complex multi-instrumental tracks on this set is not an issue at all.

The cohesive performance of its tri-brid driver configuration of this one is quite astounding on how fast and responsive its dynamic driver is while the supporting other types of drivers are quite sensitive and responsive  gives a detailed, clear and less distorted sound reproduction and smooth yet airy presentation of its SONION electrets. On resolution capability, this set is quite resolving on both macro-dynamics and micro-detail retrieval as its solid note texture while its micro-detail definition is able to capture some nuances and details like vocal ends, attacks and reverberations.

PEER COMPARISONS:

LETSHUOER EJ07M

• Like the XUANWU GATE, EJ07M also has a tribrid set-up consisting of 1 dynamic driver, 2 Sonion balanced armature drivers and 4 Sonion “ESTs” and also encapsulated in solid stainless steel shell chassis but in a more compact size. Both sets have a generous amount of accessories inside their respective packaging box but the stock cable of EJ07M is not a modular one.
• As for tonality, both sets are on the neutral side of tuning as I also classify the EJ07M as a balanced-neutral sounding one. Compared to the XUANWU GATE, the EJ07M has a more tad more mid-bass texture, similarly well-balanced and neutral midrange presentation albeit the EJ07M is less energetic, and smoother, less brighter yet airy treble response.
• When it comes to technical capabilities, both sets are actually trading blows in one another, While XUANWU GATE has a wider sound/speaker stage but the EJ07M has better stereo imaging as it projects a more holographic presentation and a tad more accurate on locating certain instruments and vocals.

KINERA IMPERIAL URD

• One of the tri-brid driver set-up IEM model from Kinera on the midrange as it has 2 dynamic drivers, 1 custom-built balanced armature driver and 2 Sonion “ESTs” albeit unlike XUANWU GATE, IMPERIAL URD has a resin shell chassis. Both sets have a generous amount of inclusion of contents of their respective product packaging box and their stock cables have a modularity option which makes them versatile on different audio jack outputs.
• IMPERIAL URD has this warmish-neutral sound which makes it a bit more coloured compared to XUANWU GATE. Its bass response is more impactful and tactile compared to XUANWU GATE, a tad more textured and rich midrange presentation but well-composed, smooth treble response which makes it a bit darker sounding with just a moderate amount of treble air.
• As for technical performance, compared to XUANWU GATE, this one is fall short in almost all categories as it has a bit narrower sound/speaker, a two-dimensional stereo imaging with less defined placements of vocals and instruments in a soundscape but at least it has good separation and layering. Its macro-dynamics somehow has a bit more solid note texture.

FEARLESS AUDIO ROLAND

• This model was actually my first taste of a tri-brid driver set-up as this one has a single dynamic driver, dual balanced armatures and quad Sonion “ESTs”. But unlike XUANWU GATE, this unit has a resin shell structure and its stock cable doesn't have any modular features as this was an older generation of tri-brid driver IEMs from the previous decade.
• As for its tonality, The ROLAND has a mild U-shaped sound signature which is a bit coloured compared to XUANWU GATE as it has slightly recessed midrange presentation with a more punchy and slamming bass response, a warm midrange which adds more heft and depth on male vocals,and then a more smoother and less sparkly on the brilliance treble. Therefore, its airy extension is rather modest.
• On its overall technical aspects, the ROLAND has just an above-average sound/speaker stage dimensions which gives a bit on the intimate side, a concave stereo imaging and somehow, it has a good separation and a multi-layered presentation of its soundscape. The ROLAND also has excellent resolving capabilities for its own performance with good cohesiveness of its tri-brid driver system.

To summarise and in conclusion of my assessment of this set, It proves that TANGZU has a capability to create a product in every part of the price segment in the audio market. It shows its testament as a reputable audio company to create a beautifully-crafted set with a phenomenal sound quality for discerning ears of audiophiles and audio professionals alike.

If you are a neutral head type of listener who  doesn't want a less colouration of the sound quality, the Xuanwu Gate is a must have one that will truly define listening pleasure.
