Designed for the HS2000MX MK2, this ACT06 (German silver, copper alloy and white jade) module uses the "10mm Myrinx WS driver" configuration elements from the ACT03 and ACT04. This is Acoustune's first attempt to use stone materials in the housing. While utilising the traditional vibrating diaphragm material "Myrinx" thatAcoustune has been using, adjustments to the coating material and optimisation of themagnetic circuit are made to accommodate the newly adopted stone material, white jade while maintaining the same diaphragm shape. The acoustic characteristics are tuned to provide thickness in the vocal range.

Acoustune's got us now in a pickle. This new flagship in 2020 helms the Pentaconn campaign with new rumbling lows and everything worthy of a full Tolkien war scene. Retaining the Acoustune signature sound, re-discover the definition of timbre, tone, accuracy and what it means to have full gratification without notes indecisively bleeding into one another.  We don't know how to choose, so we'll let you. // Launched 28Jun2020 in Zepp alongside the HS1657Cu and HS1677Ss. The new Pentaconn-ear series is ready to face the Head-Fi competition, head-on. Click here for more engineered gems by Acoustune.

Acoustune's gold standard now lies in the pure silver ACT47 module found aboard its HS2000 MKIII flagship. This single-dynamic driver marvel pushes the boundaries of Myrinx technology, the brand's renowned driver material. Paired with a silver ACT47 chamber and ARX500 cable, the HS2000 MKIII delivers unmatched sonic performance. A decade ago, Acoustune stunned the audio world with Myrinx, a revolutionary driver material. The HS2000 MKIII showcases its pinnacle: a diaphragm made from medical-grade polymer biomaterial, topped with a Japanese-made beryllium thin film dome. The pure silver ACT47 chamber meticulously extends high frequencies, creating an even richer soundscape. [See Product Desc. For More] Completing the audio symphony is the meticulously designed ARX500 cable. This 8-core hybrid masterpiece blends silver-coated OFC and ultra-fine OFC wires, meticulously enhanced by Pentaconn Ear connectors. High-precision metal components throughout the cable ensure sonic harmony and a touch of luxury. This revolutionary earphone breaks new ground with its cutting-edge technologies and materials. Acoustune's unique combination, previously impossible due to production challenges, offers smooth, linear sound reproduction with rich, controlled bass. The highly rigid metal dome eliminates unwanted resonance, ensuring precision that rivals a perfectly synced orchestra. The HS2000 MKIII's innovative housing allows effortless switching of the included ACT47 chamber with future options, upgrades and compatible legacy chambers.

Groundbreaking flagship model from Acoustune took Head-Fi up a notch, creating a different level of modularity by their new capsule design. With the HS2000MX ("笙 Sho") you can look forward to future releases, such as the limited edition ACT02 in brass. // The Myrinx Composite Dynamic Driver Acoustune fans are familiar with the Myrinx composite dynamic driver with the past launches. In this HS2000MX "笙 Sho", add a Japanese beryllium thin-film dome, a material that is hardly used due to the combination of availability, mass production and cost. In addition to the smooth, linear reproduction and rich bass of the dynamic driver, the highly rigid metal dome suppresses resonance and delivers a tight, controlled bass, like a well-coordinated orchestra. // Acoustune Capsule Technology (A.C.T.) A key feature of the Acoustune range so far has been its modular construction, with the acoustic chamber and the mechanical housing completely separated. Now the modular construction has been further developed. By opening and closing the high-precision, rattle-free movable outer housing, the acoustic chamber can be replaced by the user, allowing for future options and upgrades. // ARS100 cable for "total balance" After much trial and error in terms of wire material, number of cores, and weaving method, we finally adopted the ARS100 series, which is equivalent to the standard product, considering the high level of perfection of the cable and the balance of the entire earphone. The ARS100 series is the same as the standard ARS100 series, but with a 16-core hybrid structure of silver-coated OFC wire and ultra-fine OFC wire, as well as NDICS Pentaconn Ear connectors. In addition to the high-precision metal parts, the colour of the earphone itself, indigo, is also used for the metal parts such as the connector, splitter and earphone jack to harmonise the entire aesthetic of the Sho.  

HS2000MX MKII is a delicious red and houses a brand new chamber, the ACT05. This new ACT05 is made of Oxygen-Free Copper (OFC) and worked with same Myrinx* Composite dynamic driver that has been highly evaluated chamber modules ACT01 and ACT02.*The Myrinx's diaphragm is made of a medical grade polymer biomaterial. The dome is made of a Japanese beryllium thin film. This is a material that has never been used in a conventional product due to the combination of availability, mass production andcost.

Cayin Audio were R2R pioneers in a smart music player, but the advent of the R2R RU6 USB-C DAC/amp dongle establishes them as masters of the fully-discrete resistor DAC topology in portable audio. Entering 2022, this is all it takes to achieve the buttery, natural and resolving sound, plus imaging depth, R2R is known for. Building a discrete R2R DAC in N6II/R01 had already been no mean feat. Yet to have gone one further, and implemented a 4.4mm DAC dongle for Android, iPads and laptops is a most ambitious step for R2R. It's worth it to Headfonics who cite RU6's "analog" approach, and the innovation extending to its volume control is lauded by Headfonia. [See Product Desc. For More] It gets harder every time it gets smaller, so RU6 marks Cayin as masters showcasing how they can make it work. Descended from R01, RU6's boasts a chain of 96 0.1% precision, temperature stable, resistors. That imparts a fidelity to mobile audio not yet experienced. Over 200 mW of balanced power gets most earphones and headphones loud, on the move. ecoustics say RU6 "is not only very unique but also one of the best of its kind". Everyday Listening rates "RU6’s wide stage and analogue-like note presentation granting it one of the sweetest and most euphonic sounds I’ve encountered". After thorough comparisons with other options, Twister6 qualifies RU6 as capable of replacing entry-level music players. Prime Audio Reviews confirms it differentiates itself from other DAC/amps, and it's Ear Fidelity's Best Portable DAC of 2021. Your music will be decoded up and down RU6's 24-bit ladder of individual resistors, crammed into its thumb-sized chassis over two separate six-layer PCBs. The actual R2R ladder DAC is kept apart from signal processing to lower noise. We pay attention when Cayin implement RU6 ala typical R2R – with a NOS (non-oversampling) mode. That's double the feat because the precision demanded goes up. Amidst minimal digital filtering, R2R's analog-like goodness gets delivered unmolested to your ears. Lovers of reference sound need not fret, however, with RU6's ability to switch from NOS to oversampling mode for the cleanest possible result. That scrubs any last distortion and artifacts beyond the audible human hearing range, leaving you to just enjoy your music, naturally, via one more Cayin innovation yet. That precision is backed up by a low-power, fully analog, volume control solution. A series resistor operates with shunts as voltage dividers in tandem with relays, to maintain near-perfect resolution of your music and a signal-to-noise ratio of over 110 dB. A totally novel volume solution has made this a feat for a USB-powered dongle DAC; let alone a R2R one.  Take all 30g of the RU6 built from CNC aluminium with you in your pocket, bundled with a USB-C cable as stock for all your mobile devices, with additional leather cases and Lightning-to-USB-C cable (not MFI-certified) sold separately.  Also check out the rest of Cayin's releases here, or view our other DAC/amps here.
