Ideal for Audiophiles

These Amps & DACs are designed for discerning music lovers. If you are someone who cares about audio quality deeply, you'll want a pair of Amps & DACs like these. You can expect these Amps & DACs to present you with a refined listening experience. The audio quality exhibited by these Amps & DACs is a beautiful mix of musicality, technical brilliance and high precision. These Amps & DACs deliver a spacious and open soundstage that compares listening to music on actual speakers.

Best Suited for Portable Use

The ability to carry your favourite headphone around is priceless for those who value them. These headphones and devices offer the ultimate portability experience without sacrificing sound quality. If you’re someone who appreciates cutting edge engineering, quality sound and portability, then look no further. Designed to be trusty companions, these headphones and devices are cleverly engineered with the latest technology to offer the ultimate combination of portability + hi-fidelity.

Metal build

The longevity of your headphone/devices is strongly affected by its build quality, and a poorly built pair is more susceptible to breaking in a short amount of time. This is even more important for the listener who travels with their headphones/devices frequently, as wear and tear are more probable.Headphones/devices built with metal and metal components usually tend to last longer and can withstand wear and tear and potential damage. Modern processes allow all kinds of precious and durable metals to be used while making devices and offer a longer lifetime for users.

Pair with Laptop via USB

A majority of people use a laptop as the primary source device to listen to music or watch movies. Since the laptop is an essential part of the audio chain there are headphones and devices designed to work a laptop or computer system flawlessly. With the availability of USB connectivity, it becomes easier to pair various devices like an Amp, DAC or even headphones without worrying about drivers or any additional piece of software.

Volume Controls

If your Amps & DACs have volume controls, you will be able to adjust the volume level with a simple touch of a button without having to reach for your source device. Your music keeps playing without being interrupted or accidentally paused during playback. Having volume controls on Amps & DACs or at least in-line controls on the audio cable may seem unnecessary to some people, but they are, in fact, quite convenient.

Super Lightweight Design

When you want to be constantly hooked to your music, you’d need a pair of lightweight headphones – one that you can wear and forget about instead of one that keeps pressing you down with its weight. And contrary to popular belief, the sound quality of your headphones doesn’t change with weight. Recent designs have combined durable, yet light materials to construct lightweight headphones that are sleeker, trendier and more comfortable than ever before. Of course, lightweight headphones are also easy to take along wherever you go – they don’t add weight to your bag or occupy too much space.

An R2R DAC is pretty much the buzzword of the year. Everyone wants one, but most are incredibly expensive and need a big fat setup. The Cayin RU6 is set to change that. Pocket-sized, on-the-go, R2R goodness for everyone.

INNOVATIVE 24BIT DISCREET R-2R RESISTOR LADDER DAC CIRCUIT

The Cayin RU6 features a self-developed 24bit discrete R-2R resistor ladder circuit that can decode up to 384kHz PCM audio. The basic idea of the R-2R ladder is a matched pair of resistors, the first is “R” and the other is “2R'' which has twice the value of R. To achieve 24-bit decoding, RU6 equips 48 units of resistors (23 x R and 25 x 2R), and that’s for one channel. So for a stereo 24 Bit R-2R decoder, RU6 features 96 units of resistors for life-like audio reproduction. With the advent of the R-2R circuit, Cayin RU6 establishes itself as the master of the fully-discrete resistor DAC topology in portable audio.

OFFERING OVERSAMPLING AND NON-OVERSAMPLING DA MODES

Cayin offers both Oversampling and Non-oversampling DA modes in RU6. For Oversampling mode, the Digital Audio Bridge will upsample the digital audio data to 384kHz through digital filters. This will enhance the resolution, reduce noise and improve the anti-aliasing of the digital signal. The Oversampling DA mode will offer a noticeable improvement in details and frequency extension. The playback is clean and sharp with a darker background. On the other hand, NOS DA mode maintains the sampling rate of the original bit-stream and playback will become very musical with a natural and organic presentation.

EQUIPPED WITH FULLY ANALOGUE RESISTOR ARRAY VOLUME CONTROL

The majority of USB DAC/Amps rely on your phone's volume control to regulate the headphone output volume. Technically this was not a viable solution to Cayin RU6. Cayin created a fully analogue resistor array volume control circuit in response to this problem, offering 99 steps of volume adjustment via nine segments of resistors and switching relays. Resistor Array volume control features a very high-quality volume control design, extremely transparent when implemented correctly. This design is incorporated in a lot of high-end preamps and integrated amplifiers.

FEATURES DUAL CIRCUIT BOARD LAYOUT FOR DSD AND PCM PLAYBACK

To minimise audio signal interference, Cayin has split the RU6's circuit into two 6-layers PCB, with digital and analogue circuits installed on separate boards. This safeguards the audio signal integrity and ensures the noise from the reference clock and DSP does not bleed into the amplification circuit. This architecture in turn delivers artefact-free audio every single time. This circuit design combined with the R-2R architecture enables the RU6 to support hi-resolution PCM and DSD audio formats with support for 384kHZ PCM and DSD 64/128/256 natively.

INTUITIVE AND VERSATILE OPERATION WITH LOW POWER CONSUMPTION

Discrete R-2R circuitry is a low-power DAC circuit when compared to other highly integrated DAC chipsets. Because of this architecture, you can listen to music without worrying about your phone's battery draining out. USB-C connection offers compatibility with a wide range of phones, consumer electronics and computers. The hardware is intuitively designed, with the volume controls serving as menu selectors and the OLED screen displaying playback information. The Cayin RU6 also offers two gain settings to enhance performance with various IEMs and headphones. All this is wrapped in a 28g package.

Excellent USB DAC

Tried with both IOS ( iphone 11) and android LG G8x.
Initial impressions: no regrets
Probably the best usb dac in market right now.

Currently using - Earmen sparrow and LP W2. This is definitely a good addition to them

Using to drive primarily IER Z1R , UM MEST MKii , IMR EDP+

Excellent tonality and bass. Widest sound stage you can get through a USB DAC till now.

Really impressed. As many say it requires some burn in, hope it may open up better and settle on treble.

Immersive, Natural and Detailed

Pros
1) Natural sound signature that is forgiving of even low resolution mp3 files but scales well with hires files.
2) Quite holographic soundstage and good imaging capabilities
3) Very dynamic sound signature with great bass thump and impact
4) Treble is detailed but not sibilant or overly sharp
5) The least expensive R2R Dac out there in the market
6) Powerful enough for almost any iem in the market

Cons
1) Not a truly balanced circuit despite the 4.4mm port
2) Rare instances of EMI interference noises
3) Volume changes can sometimes be a bit slowdue to the switching relay resistor volume control

My Setup
Smartphone: Oneplus7Pro
Apps used: USB Audio Player Pro (bit-perfect playback with Tidal and Qobuz integration), YouTube vanced, Apple Music
Iem used: 7hz Timeless through the 4.4mm port

First of all thanks to Headphonezone for bringing this unique product to the Indian market. The USP of this product is that this is the world’s first R-2R Dac in dongle format. R-2R Dacs are generally known for their more natural sound signature and huge difficulty involved in engineering one correctly as precise resistors have to be hand selected and arranged in ladder format. This Cayin RU6 uses 96 precise resistors in ladder form for 2 channel audio.

The combo of Cayin RU6 plus 7hz Timeless produces a highly dynamic, engaging, and wide sound signature. The naturalism of the R-2R Dac especially helps in adding more midrange lushness to the sound signature of the 7hz Timeless compared to my Hiby R3 Pro Sabre Delta Sigma-based DAP which I used earlier. The soundstage also gained a more holographic nature with the Cayin RU6 compared to the Hiby. Songs such as ‘Thriller’by Michael Jackson, ‘Jack Sparrow’ by Royal Philharmonics Orchestra as well as ‘Doors and Distance’ by Antonio Sanchez illustrate the soundstage capabilities of the RU6. ‘Chali Kahani’ from Tamasha gives a clear illustration of the great dynamics of RU6.

A note on value for money: This is priced at the Summit Fi range of dongle dacs at the moment and encroaches upon the price category of a Mid-Fi Dap such as Shanling M3X. I would say that for anyone ok with carrying a dongle with their smartphone, RU6 is a great value for money product especially when you consider the high-end and niche tech inside as well as the highly natural and engaging replay of music offered by the RU6.

Hi Harisankar,
We are so happy you took out time & elaborately reviewed the product. We are sure this will help our customers to make an even better & informed decision.

One of the best dongle dac

Hi all
I bought cayin RU6 because I wanted to test the R2R technology.
The dongle is very well built. The type C poty, the chasis, the SE and balanced ports look premium. The matte finish of sides and back, glass front, the metallic line along the sides - all look very good. This is a sturdy device. The buttons are kept at horizontal orientation to the sides rather than conventional parallel orientation. They work perfectly.

Connection was easy. Just plug and play.

Setting- three settings. Gain - high/ low, sampling - OS/ NOS. OS is oversampling, which makes the sound slightly warm and add more flavor to it. NOS is slightly boring but detailed. Last is screen backlight timing. These can be changed just like looto paw.

Sound- Accurate and lively. Details- its NOT one of the most detailed dongle DAC. That accolade belongs to Looto paw s1 and L&P W2.
Soundstage- definitely one of the largest, if not the largest among dongle dacs.
Localisation- average. Sound notes mix together and less separation among instruments. So pin point accuracy of instruments on soundstage not possible.
Highs- they are well represented.
Mids- Lush and full vocals. Both male and female vocals feel very good. Its not mid-forward presentation but gives perfect representation.
Bass- very good, solid bass with good sub-bass and reverbs. Not the fastest like A&K dongle. But still very well regulated. Slight bass bleed to the mids.
Power- good for iems. Not for power hungry cans but its understandable.

Tonality- here W2 and DAPs like ibasso dx160 and m11 plus are slightly ahead. Overall very good DAP like tonality compared to many other dongle dacs available in market.
Timbre of instruments- its accurate and lifelike

Competition- L&P W2 is priced similarly. Both are good. W2 slightly ahead in SQ but background noise in W2 is more while streaming.
Its ahead of looto paw S1 and A&K dongle in terms of tonality and presentation.

Overall verdict- if you wamt to experience R2R technology, this thing doesn't disappoint. Good organic warm sound with good technical capabilities. It'll be among top 5 dongle DACs definitely.

Hi Samrat,
We are so happy you took out time & elaborately reviewed the product with a comparison. We are sure this will help our customers to make an even better & informed decision.

R2R DAC in such a small form factor is insane. It sounds incredible. In the space of compact dongle DAC the RU6 definitely shines and provides insane value for money.

Thank you for the awesome reviews & ratings Yash!

Endgame Dongle DAC

How does the RU6 sound? One has to listen to it to understand - once you've heard the RU6 you can't go back to anything else. Just a few hours of listening on my HfiMan Edition XS and Sennheiser HD650 - and I was packing up 3 of my desktop DACS - Hidizs S9 Pro, Topping D10 Balanced and Aune X1s Pro - and listing them on HPZ's Trade Up Program. The RU6 just makes everything sound so much smoother and enjoyable - takes the edge off by just the right amount - without losing out on detail. Listening to "Charles Watts' Watts At Scotts' " - a recording that has a pronounced top end which was getting fatiguing on other setups - the RU6 did its magic and I was enjoying it like I never did before. I even tried it with my Grado SR80e - which also accentuates the top end in my experience - and wasn't disappointed. If this is what R2R sounds like - then I can't wait to save up enough for something like a Denafrips

Absolutely hooked

The Cayin RU6 is equipped with an R-2R DAC that is in producing a really natural sound. It’s extremely small & easy to use so no complaints there. The player also lets you switch from (NOS) to oversampling mode easily scrubbing any last bit of distortion. A cherry on the cake is that this dongle is backed up by a low power volume control solution. Thank you headphone zone for the fast delivery!!

Happy to know you are loving the RU6 Gajendra. Hope it was a comfortable shopping experience. Cheers!
