    Cayin RU6Cayin RU6

    Cayin RU6

    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.

    Questyle M15Questyle M15

    Questyle M15

    Questyle Audio adhere faithfully to current-mode amplification at all form factors, and building a 4.4mm balanced output into the M15 just extended the capabilities of their flagship dongle. Headfonia says "M15 offers one of the most sophisticated designs in the industry". ecoustics rate it on par with legacy music players and "would suggest trying it before you pay for anything else". MOONSTAR Reviews echo M15 competes on equal terms as music players. Headphonesty hail it as liquid gold. M15 "managed to wring musicality out of the ESS DAC chip that I frankly did not think possible" praised Headphone Guru. It's easy to hear why, if audible results count to you. Operating in current-mode, audio signal gets passed in current instead of the more standard voltage. The Legend Evo from Empire Ears provides instant synergy, given its 3ohm load. Current-mode amplification eliminates the lag time of the signal that might otherwise occur, as it builds up at the capacitances in the circuit – current signal passes through unhindered as compared to voltage, with speed and ease. [See Product Desc. For More] By doing away with the issue of transmission delay in M15, Questyle virtually eliminates any of the harshness caused by the intermodulation distortion associated with high capacitance, solid-state circuits. Typical of their high-end offerings, M15 decodes digital via its ESS Technology ES9281AC DAC smoothly and organically, without exaggerated warmth or bloat.  That small signal then takes advantage of being unhindered by capacitance in the signal path. An added benefit from current-mode amplification is that huge signal bandwidth is possible, leading to phase response being accurately preserved in the human hearing range. Indeed, to hear current-mode is to hear a naturalness to music not encountered before in a conventional circuit, and Questyle build M15 as an affordable entry to such a topology. Happily use with any low-impedance device (current signals excel the closer a load is to ground) such as Rosson Audio Designs, the Vision Ears Elysium EXT, plus CIEM heavyweights Craft Ears and Empire Ears – particularly the latter's Odin and Legend Evo. Driving low impedances is M15's forte. But bridge-tied load balanced operation now means this dongle also doubles voltage swing compared to single-ended operation, to drive higher impedances credibly too.

    Questyle Audio adhere faithfully to current-mode amplification at all form factors, their dedication to this technology extending down to their thumbdrive-sized DAC dongle, the M12.  It's easy to hear why, if audible results count to you. Operating in current-mode, audio signal gets passed in current instead of the more standard voltage. This eliminates the lag time of the signal that might otherwise occur, as it builds up at the capacitances in the circuit – current signal passes through unhindered as compared to voltage, with speed and ease. [See Product Desc.

    Cayin C9Cayin C9

    Cayin C9

    Cayin Audio's famed amplification packs up to join you back on the road with the launch of C9, featuring 4.4mm and 3.5mm inputs and outputs. Headfonics praise it to the roof as it "revitalises tubes on the go, a traditional niche in our hobby that seems to be forgotten", going on to name it Best Portable Amp of 2021. This battery-powered, tube and solid-state hybrid lands in time for use on your office desks and in hotel rooms, establishing your reference headphone listening anywhere you so choose. [See Product Desc. For More] C9 is a fully-balanced, truly differential amplifier built upon the essentials establishing a device as basically thoroughly engineered. READ ALSO The full blow-by-blow story of C9's technical innovations A high operating voltage of more than eight volts and a reliance on discrete parts for over 90 per cent of the design means C9 is not only capable of putting out over 4 watts per channel, but also ensuring it is the cleanest, most linear kind of signal possible. Achieving 125dB of signal-to-noise ratio would not have been otherwise possible in a discrete design, with all the benefits that brings, without exacting layout. The input section exists on the popular Nutube. C9's dual timbre circuit revolves around two of Korg's fluorescent triodes or toggled solid-state FETs, the philosophical transistor alternative. READ ALSO C9 blurs the line with desktop amplifiers The delicate input signal is then passed to a discrete solid-state output stage that can be switched between working in pure Class A mode or Class AB. Built with individual transistors of Cayin's choosing allows great control over tuning and an innately linear open-loop circuit, with minimal negative feedback, to be fashioned, while producing genuine current for demanding headphone loads. C9 is a brute in ballet shoes, confirmed by the big volume pot controlling dual precise MUSES resistor ladder attenuator parts occurring after the driver stage, kept far from the input signal for maximum integrity.  Line outputs from Cayin's own N6II/E02, HiBy Music's New R6 plus R2R RS6, and iBasso Audio's DX320 will never be better pampered than via C9. Use it in a mobile stack acting as the platform for Hedd's HEDDphone® – absolutely recommended, says Ear Fidelity – MYSPHERE 3.2, Rosson Audio Designs, plus almost any ABYSS or HIFIMAN, to shine. "And while DAPs come and go", Twister6 believes "C9 should last you a while to enhance any source you pair it up with". Headfonia say it "should really be the first amp to look at to get four completely different sound signatures that's simply impressive".

    iFi iDSD Diablo

    If the devil is in the details then iFi Audio named the iDSD Diablo aptly. The heights the proven platform that was Micro iDSD Signature gets taken to the rafters with its further optimised circuit and boutique parts overflowing from its red, race car chassis. iFi's usual custom operational amplifiers show up here in a design that boasts more careful application of local negative feedback, rather than the more standard global variety. It's Headphonesty's "unique mix of raw, fire-breathing power and refined audio perfection in a no-frills portable package". [See Product Desc. For More] By using sparing error correction, iDSD Diablo veers from the glare and harshness of cheaper solid-state designs caused by transient intermodulation distortion, with the signal from dual Burr-Brown DACs still being clean and precise throughout. Purewave, the name coined for the direct-coupled analogue circuit developed for iFi by Hi-Fi and Parasound legend John Curl, ensures a fully balanced, differential signal path produces minimal distortion and up to 120 dB of signal-to-noise ratio.  Such performance is possible also due a high 15 volt operating voltage – a number much more akin to desktop amplifiers – that expands headroom and circuit linearity in tandem with Diablo's local, carefully applied, negative feedback. That precision gets backed by even more power: nearly five watts stands ready to drive any headphone load, including a HEDDphone®, HIFIMAN, MYSPHERE 3.2 and Rosson Audio Design. Accessorisation fitting for the premium status of this red arrow is included, not least a carrying pouch that'll accomodate iFi's low-noise iPower DC charger and a 4.4mm balanced line-out cable to dual XLR cables, to feed a desktop amplifier. Trusted Reviews awards it 5 ⭐, praise that is matched by Headfonics saying "sonically it's the best iFi DAC amplifier made up to date".

    Ferrum OorFerrum Oor

    Ferrum Oor

    It's quite clear being named Oor (meaning 'ear') how Ferrum Audio intended their dedicated headphone amplifier to be enjoyed. Yet under the hood, there's so much to chew on from the collaborators of Mytek Audio's meteoric rise, about their compact overachieving flagship built to drive the best Head-Fi has to offer. Still we let the accolades judged by ear pour in from seasoned reviewers hailing EISA's Best Headphone Amplifier of 2022 supreme. It's on Headfonia's Recommended Buys list for a reason, and Headfonics were equally sweeping in their praise. [See Product Desc. For More] Oor was too fun for Soundnews who put Ferrum's upstart against the industry's top dogs. Even Hi-Fi-centric Part-Time Audiophile awarded it an Editors Choice, and Hi-Fi News an Outstanding Product award complete with measurements.  In Oor is the complete package. Ferrum managed to balance the demand for neutrality in a flagship source, with the deep, impactful bass of a DC-coupled design. The technical chops are on show throughout by the proudly Polish HEM, who built Mytek but know a thing or two about circuit design themselves.  Oor's business side of things – a power stage consisting of a discrete transistor op-amp designed from the ground up – remains inherently linear. Even before negative feedback is applied.  Excellent frequency response in the open-loop, without coupling capacitors in the signal path, allows excellent low-frequency performance guaranteeing tight bass. And high-frequency extension soars to 60Khz, before negative feedback took that out flat to 100Khz. Phase response in the human hearing range is stellar, for potent, precise and hard-hitting dynamics to show off your flagship headphones. READ ALSO The inside story designing Ferrum Oor Feedback is not of the ordinary variety either, with current feedback providing speed of the loop gain through the capacitance of solid-state transistors for low transient intermodulation and slew-induced distortion.  Ferrum make their good Oor great, meanwhile, biasing the transistors making up their proprietary power stage in novel manner. Sitting between a sliding bias Class A and high-bias Class AB output stage in definition, Oor achieves the best benefits of both – highly linear transistor operation, plus high efficiency and lower quiescent current and heat. Thus is 8 watts of power delivered into HIFIMAN's Susvara achieved. Oor gives you power in quantity as well as quality. Certainly the same thing can be said about the listener's level of enjoyment too, regardless of headphone. Take Oor up another notch with the addition of the HYPSOS power supply, browse all of Ferrum's products here, or view our other desktop devices here.

    Who Is The Portable Headphone DAC Amp For?

    A portable DAC amp is a multi-purpose audio device. It interprets digital information, converts it into analogue audio, amplifies the signal, and outputs the superior-quality music to your analogue headphones. The portable DAC amp is for anyone who wants to indulge in superior quality audio without the bulk of a desk DAC amp or when they are commuting.

    Is a USB C Portable DAC Amp Worth It ?

    As a portable device, a USB C DAC amp can be tucked away in a pocket and is a great partner for Android users (iPhones users can still benefit from this audio device with a USB C adapter). Oftentimes, the built-in DAC in phones is unable to do justice to the original recordings of our music. How often do you find yourself constantly turning up the music volume just to try to recreate that “oomph” you left was lacking?

    Not only does doing so hurt your ears, but it also introduces more noise to the music. The portable DAC amp is an excellent solution to enhance the audio quality and have your headphones work at maximum capacity without turning up the volume to the maximum. The result is that you will be able to listen at normal volumes, while enjoying all the tones of the recording!

    The portable USB C DAC/amp solves many issues that internal DACs of a smartphone or laptop are known for. If your devices produce background hiss, unwanted noise, low headphone volume, poor sound quality or does not support specific file data rates, getting a portable DAC amp for your headphones solves these problems, while improving the musical experience, all without damaging your ears.
