It was entirely coincidental that I met HiBy Music at the Guangzhou Audio show in November 2017. I needed some R’n’R after visiting some factories and decided to wander upstairs where the HiBy booth was located.

They were showing the original R6 stainless-steel ‘Domestic edition’ for the first time and wanted me to guess the price and demo it. I guessed $800, my bad, it was $599 and now $499 direct from their online store.

Since then the R6 grabbed a 2017 DAP award from us and made a hell of a lot of social noise from buyers and the general portable audio community. It was largely a success as a freshman digital media player with some killer features.

Roll-on 2019 and now we have the new R6 Pro DAP priced at $799 (was that my fault?). Why did this come out if the R6 was such a success?

Well, technology never stands still, Android is up from 6 to 8 with LDAC and more than a few of us want that high output impedance lowered. HiBy responded but I can tell you now the R6 Pro is not just a feedback fix, there is more to it than that.



What’s New?

Quite a few things actually though the basic form factor and platform remain the same on a macro level.

New Amp stage

The first is that output impedance on both its 2.5mm balanced and 3.5mm unbalanced jacks. This was a polarizing topic the minute the 10Ω spec sheet was released for the original R6.

Low impedance IEMs would have to be jacked via an iFi IEMatch cable (an accidental hero, much to iFi’s delight I am sure) to prevent what we call low-z skew. This is basically where the frequency tuning takes a turn away from what you expect, such as a darker tone or less bass. It seemed to have an effect on very sensitive IEMs, particularly BA designs.

The R6 Pro remedies this with a complete amp stage overhaul. Out goes the TI dual TPA6120A and OPA1612 amp stage and in comes four Muses8920 and an SSM6322 from Analog Devices.

Not only will this reduce the impedance level to less than 0.5Ω for both balanced and unbalanced to match better with sensitive IEMs but will also change the tonal balance and maximum power output rating. In short, the R6 Pro output is more stable and much more powerful than the older R6.

Output configuration

The final part of the amp stage overhaul is the jack configuration. Out goes the older 2.5mm balanced jack output and in comes the more modern Japanese NIPPON DICS 4.4mm pentaconn balanced format to match the likes of iBasso, FiiO, Cayin and of course Sony.

Oreo

The second change is the software platform, moving from Android 6 to Android 8, or Oreo. Why is this important? Quite apart from the “keeping up with the Jones’es” element in 2019 it also brings in a few new features as well as allowing HiBy to retain their bit-perfect DTA Architecture.

The key new feature for me is the ability to transmit BT LDAC (and HWA) out of the box which Android 6 did not offer. Ironically, this brings the stock R6 Pro up to par with their junior R3 which is also now LDAC capable.

Legacy Features

They would be mad to ditch the ‘baby with the bathwater’ in terms of what people loved about the R6. Thankfully HiBy thinks the same way.

So that means the same 3GB RAM and fast Snapdragon 425 SoC experience. The lovely 2.5D Glass small bezel IPS screen and the stainless-steel body (no aluminum at the time of writing) stays. It also means a return of the ESS ES9028Q2M dual DAC implementation and the brilliant MSEB DSP software.

Design

This is almost the same stainless-steel design as the R6. For those new to the R6 Pro, this means a corrosion-resistant 316L stainless-steel block with some beautiful CNC curving. This is a “pointy” sharp-edged free design and feels a ‘smooth as butter’ in your hand.

I had remarked in the original review that HiBy had some Sony design cues in the R6 and I guess it is the same for the R6 Pro. However, the 4.4mm area lacks that contouring on the other 3 sides so not quite as symmetrical as the first R6. In all, a slightly traditional rectangular shape with concaved accents top and bottom to protect all but the 4.4mm socket.

Side by side there are some slight changes to the dimensions to accommodate the larger 4.4mm jack output in part at the top and a slightly longer housing below the base of the LCD screen. The USB-C socket at the base of the new R6 pro is also a little more centered than the original R6. Apart from that the button configuration on both sides and the memory card slot remain unchanged in both form and function.

Dimensions

We have added the dimensions and weight to our ever-growing DAP table below. As you can see it does differ slightly to the original R6 being slightly longer and just fractionally wider and deeper. It also carries an additional 10g in weight.

On a day to day handling. however, it is unlikely you would ever notice those additional mm’s over the original and even optional accessories such as the nice blue leather case for the original R6 fit the R6 Pro quite well without covering the buttons. This is still a very compact single-hand friendly digital media player.

However, there is no word of an aluminum version as of the time of writing so that 285g weight is fairly chunky compared to competing DAPs at this price point. I like chunky, call me old school but you may not be so inclined.

Screen

The R6 Pro retains the same screen as the original R6 which is a good thing in my book. This is a capacitive 4.2″ IPS TFT screen with a 350dpi 16m color 1280 x 768 px resolution.

This is a bigger and better performing LCD screen than the X7ii.  The X7ii lags behind with a smaller 3.7″ IPS TFT screen with just a 233dpi and 800×480 px resolution. The R6 Pro is on par with the DX200 and DX150 which both use a 4.2″ IPS 1280 x 768 px touchscreen.

The viewing angle on the R6 Pro is fantastic. The screen is legible from a virtually horizontal position. The color saturation is gorgeous and seems to have superior backlighting to both the iBasso DX models. The touch response is still snappier than either of those DAPs. This is 2019 and this is still the best touchscreen I have used on a DAP to date.

Bordering

I had a real hard look up and down both the R6 and R6 Pro and the bezel dimensions look pretty much the same to me. That means a really small bezel, perhaps the smallest on the market for the size of that screen. It goes very close to a highly desirable borderless aesthetic that we look for on laptops and modern smartphone designs. There is just a slight additional bezel thickness at the bottom with an SS finish to accommodate the amp.

2.5D Glass

The R6 Pro also retains the layer of 2-D glass over the LCD from the original R6. If you look closely at the screen design you will notice a smooth curvature on the edge of the glass display known as a contoured edge. Basically, this bucks the old school design of a slightly raised bezel design with the glass sitting on top of the body creating a more seamless edge.

This is quite a high-profile design edge used now by a number of smartphone manufacturers such as Google and even Apple. Samsung’s curved glass is technically “3D” glass because of their bendable substrates and electronics whereas the R6 Pro screen has none of that.

Controls

As with most modern DAPs these days the R6 Pro can be controlled in 3 different ways; touch, physical and remote.

Touch

The touch experience of the R6 Pro is excellent, aided by that fast Snapdragon processor and 3Gb of RAM. The feeling is more in line with a decent smartphone experience than a traditional DAP.

There is virtually no lag between executing a touch command and the DAP responding to it. Everything feels snappy including the obligatory pinch and zoom multi-touch features where applicable.

Aside from that, the Touchscreen will do everything you need the R6 Pro to do outside of initiating volume control, power on/off and LCD on/off. You can however increase or decrease volume control via the touchscreen once initiated via the physical dial. Unlike the PAW Gold Touch, you cannot double-tap from the screen off option so you have to do that one via the power button to the right side.

Physical

There is no change from the original R6 with regards to the R6 Pro physical button configuration and positioning. To the left and right you get both digital volume and playback controls. The buttons are fairly flush to concaved against the SS panels but are spaced widely enough for you to be able to work with them without having to look down all the time.

On the left side are the volume controls although with Android a combination of power and lower volume will allow you to do screenshots. The buttons are easy to manage and fairly responsive in terms of potential lag between action and screen response.

On the right side, you have a slightly larger power button at the top which also doubles up as an LCD screen ‘off and on’ button. The button also holds a nifty little blue LED light which acts as a power-on indicator. The LED will glow blue during regular use but switch to red when the battery life is low and stay in red during charging until it is complete where it returns to blue.

Below the power button, you have three slightly smaller buttons, similar in form factor. They are your primary playback control buttons and will operate with the screen on or off.

Wireless

The final way is via the R6 Pro’s in-app HiByLink service. This is only available if you have both the Android HiBy Music app on the R6 Pro and your smartphone.

By setting up the R6 Pro as a HiByLink Server and the Smartphone as  HiBy Link client you can effectively control the R6 Pro remotely (Bluetooth connection is automatically done during the setup process). This is ideal for those who have their hands constantly on their smartphones but want to control the R6 Pro from a short distance on their desk or in their pocket if on the go.

During this setup, you can browse the R6 Pro’s media library, operate playback controls, adjust volume,  and scan for media. You cannot operate the R6 settings or its DSP/EQ functionality.

Inputs & Outputs

The inputs and outputs of the R6 Pro get one important change and that’s the move from a 2.5mm balanced port to a 4.4mm pentaconn compatible port. The 3.5mm and line-out/coaxial ports remain unchanged from the R6.

I am not as rabid regarding the benefits of 4.4mm over others since it is a fairly hefty and not a very discreet connector. However, I do recognize its better durability and it does bring the R6 Pro up to par with what is happening in the rest of the audio community. This keeps it competitive and compatible with the increasingly saturated 4.4mm cable market and adapters being used by everyone, including me.

As mentioned at the start there are some design changes to theR6 Pro to accommodate the new connector as well as properly centered USB-C connector at the bottom. The USB-C connection will provide for USB-DAC out functionality with PC/Macs, charging and data transfer, as well as any OTG services you wish to use.

Memory

The R6 Pro has no change in its 32GB onboard memory and micro SD card slot capacity up to a 512GB official rating. It still uses a single pin-push micro SD tray slot on the left panel. Is 32Gb a bit light for a $799 device? Maybe 64GB to match the DX200 would be ideal though you have to consider the DX200 is 1GB less RAM so give and take in the Bill of Materials here is possible (BOM).

Like before the official rating could push beyond the 512GB  right up to the new 1TB cards and beyond. This is not a hard ceiling in terms of memory capacity. Personally, I cannot test that, I tend to keep 64GB size only. I tend to find the lifespan of micro SD cards to vary and 64Gb is a more acceptable loss than 500GB if they decide to die.

Battery Life

HiBy have retained the same 4000mAh Li-polymer battery from the original R6. There are pros and cons in this move with the R6 Pro battery life.

Given there is an additional level of output power from the R6 Pros new amp stage and the higher decoding rates from LDAC and HWA I am not convinced the 12 hours rated battery life is obtainable under normal ‘audiophile’ playing conditions. It may be possible with the screen off using a lossy format with no button mashing.

However, I never really got 12 hours from the R6 either. Closer to 10 hours would be normal with no WiFi or Bluetooth. With the R6 Pro and a heavy-duty headphone combined with WiFi or LDAC BT, it drops to sub-10 hours and possibly further on DSD or Hi-res. Your mileage may vary on this one depending on how you like to use the R6 Pro.

Charging

HiBy have improved the initial charging capability of the R6 Pro over the original R6. Not that the old R6 was a slouch, to begin with. With its quick charge system, the R6 was a quick 70 mins to 70% and 140 mins to 100% using the Qualcomm quick charge system on a 9V/1.5A connection.

Now here comes the R6 Pro promising to do the first 70% in an hour or 10 minutes faster but a full 100% in 150 minutes or 10 minutes slower. A small change for the impatient ones among us. I have charged it more than a few times now from 3% and it shots up really fast on a USB 3.0 connection from my laptop so it is quite impressive.

Accessories & Packaging

There are some slight changes to the packaging, well at least to the packaging I received in Nov 2017. The box is a little bit wider than the original R6 and the rear has a bit more information about the R6 Pro, all in English. The accessories are all in their neat little individual boxes as opposed to being just bagged and tagged in the original narrower box.

Accessories

The accessory line-up in the R6 Pro looks much the same to me as the original R6 but with a few qualitative changes on the finishing of some of the accessories. You get a memory card pin, tempered glass front and back, a silicone case, USB-C cable for charging and data transfer as well as a coaxial cable. You also get a warranty card and user manual in English.

HiBy Music R6 Pro

The screen protectors are tempered glass as opposed to plain matte films which is a nice upgrade. I do think they are a touch too narrow when applied. I understand the 2.5D glass makes tempered tricky on the sides but they are narrower than the one on my R6 original and some of the glass on the front is still exposed.

The original R6 Chinese edition USB cable was a plainer rubber tubed black version which seemed a little out of place beside the supplied fancy nylon jacketed coaxial cable. Now the R6 Pro USB-C cable is the same nice finish as the supplied coaxial cable with both using nylon or a cloth-based jacket.

Case

The supplied silicone case is now completely translucent and a bit stiffer than the older charcoal finished rubbery R6 version. It does feel like it will offer a bit more protection than the original rubbery version and the translucent finish gives it more of a low-profile feel. You see less case and more DAP in short.

HiBy Music R6 Pro

That being said, I would much prefer to have seen a leather case in the box to complete the look. Silicone is a little underwhelming at this price point when the DX200/DX150 come with nice cases at $499 and $829.

I am pleased to say though that if you bought one of the nice custom leather cases as an upgrade for the original R6 then that same leather case will fit just fine on the new R6 Pro. It is not millimeter perfect mind you as the R6 Pro dimensions are just slightly taller meaning the buttons are a little closer to the edges. However, it is still 100% functional, so go ahead and buy with confidence.

    Odd, annoying review. Endless pages obsessing over every aspect of the operating system, and just a paragraph or 2 on how this thing actually sounds.
    Odd.

    • Marcus

      9 paragraphs actually. Then add in all the comparisons on sound plus the in-depth discussion of how MSEB effect sound plus synergy with various gear etc etc. Daps are more than just sound these days and they certainly do not fall under “bass, mids, treble” IEM review styles.

    R6 PRO comparison
    —Now that the FiiO M11 has been released and if u have had a chance to audition it—–which unit would you choose ?

    I will be using this dap for gym/portable player. I have some great wireless iems and headphones and want a player that can drive them with first rate sound and connectivity–

    I ordered the ibasso 220–coming Monday–for my home unit.

    Any input would be appreciated and THANK YOU for all ur great in depth informative reviews–
    Best, Scott

      I think if for the gym then the M11 is ideal as its the fastest Android DAP on the market today. I think the R6 pro might have a better level of sound quality and the Android 8 platform means its compatibility with apps will last longer than the M11 Android 7. ALso if the DX220 is incoming then upgrade it ASAP as they increased the clock speed and it is now faster.

      For wireless either is fine actually since the quality of sound will come from the built-in amp and receiver in your wireless IEMs and headphones. As far as I know, don’t quote me on this because James reviewed the M11, the R6 Pro might be more prone to EMI than the M11.

    Hi,

    Has anyone experience with running an AirPlay App on the R6 Pro and Stream from an iPhone via AirPlay? Secondly, if I hook the R6 Pro up to my stereo system by RCA cable, can I can I remotely control it from my iPhone?

    Reply
    • Marcus

      You should be able to control it using HiBy Link (BT) on the HiBy Music app though I have never tried that. AIrplay should be the same as DLNA, if there is an app for it then it should be fine.

    Just got the R6 Pro today, and it seems to be generating an awful lot of heat. Both when charging and playing music, and the battery seems to draining very quickly. What level of heat and battery drain is normal, or what did you experience?

    Reply
    • Marcus

      Run Antutu Benchmark and you can check on the heat levels. It shouldn’t be a deal breaker but the clock rate on the R6 Pro is very fast hence some heat and additional drain to keep up with it.

    Would the R6pro able to power my Hifiman arya on its own ? I am trying to keep it at a minimum no stacking and on the go. Or which DAP can be a good pairing with Arya ?

    Reply
    • Marcus

      I don’t have the Arya here to confirm but if it’s based off the edition x or Ananda and you are going 4.4mm then it should be ok.

    I’m in the market for my first DAP. I’m sure I’ll be perfectly happy with the R6 Pro but figure I might as well wait for the M11 and the DX220 reviews/impressions before I plunk down the Benjamins. Thanks for this review, it’s very helpful.

      Howdy. I’m looking for an upgrade over my first gen FiiO X7. I’m using the Empire Legends X.

      I like a balanced source signature of mids and some treble, something to pull back the leash of my X you can say.

      Should I pull the trigger with this one, or keep looking?

      Reply
      • Marcus

        I do not have the Legend X, but I do have the Phantom. I can pick up background hiss using the Phantom so is the sensitivity is the same you might need to get an iFi IEMatch cable to kill the hiss. Apart from that, you can use MSEB on the R6 Pro to tweak it in any way you want which is a big advantage.

    Hello Marcus,

    I owe Bowers Wilkins P9 and consider a new partner for it instead of my old Fiio X3 2nd Gen. The Headphones tend to also be on a warmer, darker and bassier side. My focus among all players is so far on the HiBy R6 (PRO) side. Have you tried any of or both these players with BW P9?
    I prefer electronic (psy – trance etc.) and harder arts of rock music (heavy metal / power metal). What do you think be a better choice from the both, R6 or a R6 PRO version? I love attacking sound with good but not exaggerated bass, preferably with fat mids. Thanks for the response in advance!

    Reply
    • Marcus

      Oh, the R6 Pro will work just fine with P9 with plenty of power. Their MSEB DSP is pure genius also. It will give you a wide range of tuning options to make the sound brighter, warmer, thicker, punchier – whatever you wish. Your music pretty much matches mine.

      Reply
      • Tony

        Thanks for the quick response! As far as i know R6 also has this MSEB DSP so might I potentially reach the same with a R6 Version? Will more power give a noticeable difference which justifies extra money? P9 has 22 Ohm and does not seem to be that power hungry. I live in Germany and we have extortionate prices on all these toys, so this will be even more than just 200-300 dollars extra. Thank you!

      • Marcus

        The R6 possibly but remember its stock tuning is a little thinner in the timbre and it does have far less power. I am not entirely sure how that will change things with the P9. Having said that, the P9 is not that demanding and so long as you want to stick with it and not go higher it should be fine.

        Hi, Jesus here, welcome to headfonics Mr. Trainwreck :) R6 Pro for me if not sensitive IEMs. If your IEMs are super sensitive and you do not need Android or wireless then ZX300.

      • T.J. Cook

        Thanks, Marcus.

        I have a pair of 64audio u12 and also sony mdr-z1r for home listening that I’ll use the DAP with.

      • Marcus

        The U12 I am not sure on, I would need to test it myself for noise levels.The Sony headphones would sit better with the R6 Pro since it has much more power.
