Colorfly C4: The New High End Player

When the Hifiman HM-801 player was released, I think everyone was quite skeptical on how “hi-fi” can a portable player from a relatively small Chinese manufacturer be? Fast forward a few months, and by know it’s been pretty much acknowledged that the HM-801 is a game changer, as it opens the way for other higher quality players (check out our Hifi DAP shoot-out, if you haven’t read it). Then, a buzz started brewing on a new high end player by the name of Colorfly that seemed to have a pretty good shot at challenging the established HM-801. It’s got 24/192 capability, big name Cirrus Logic D/A and resampling chip, an ultra low jitter clock, and a vintage looking design to wrap everything up. If you visit Colorfly’s brand story, you’ll read all about how Mr. Wan went at length to design his version of the next best portable player. Everybody was highly intrigued. Is this going to be another game-changer? Will the Colorfly turns out to be the new reference player in the market?

Last week, as Jaben Network puts it, “the ‘Fly’ has finally landed”. I’d like to thank my good friend Peter who has provided the Colorfly unit for this review.

Upon first impression, the Colorfly C4 is a pretty impressive sight. The wooden enclosure, the vintage finishing on the faceplate, the pro-grade ALPS slider for volume control, to the medieval-gothic emblem on the back. Just looking at the physical design of the C4, I get the impression that the designers had a really unique concept, one that is different than every other player in the market. The slider style volume control is different, and yet it works very well (hopefully we’ll see more of these around). The quality of the potentiometer quickly shows itself as I tried it with the JH16Pro IEM. This is one of the few analog pots that has totally zero channel imbalance from dead quiet to loud listening levels (about 35% up) on the JH in ears. The player is slightly bigger than the HM-801, but it’s also lighter and felt better on your hands. The wood surface is less slippery than the HM-801’s, and there is better weight distribution unlike the bottom heavy HM-801 player. The screen is also bigger than the HM-801 (biggest among the hi-fi grade players, I believe), and a digital simulation of a classic VU level meter enhances the high end feeling. On the back side, the laser-engraved logo is faultless. I don’t see a single notch of defect on it. On the bottom part, you have two headphone outs, a 1/4″ and a 1/8″, a Micro-SD card slot, S/PDIF in and out interfaces, and a USB port for charging and data exchange. I think everything has been designed very well, and I particularly like the 1/4″ headphone jack as it enables me to plug in big headphones directly with no converter.

The UI of the Colorfly is quite decent. The four directional arrows is used for navigating through the folders and menu options. There is an “M” button for accessing the system settings, and a reverse arrow button that works similar to a back button on your browser. Very worth mentioning is the two buttons on the lower left corner. The music note symbol button gives instant access to the EQ as each press on the button flicks through the available EQ: Normal – Rock – Pop – Classic – Bass- Jazz (As far as I know, the Colorfly gives no options for custom EQ). This feature is priceless for people like us, as it gives a very easy access to tune in the EQ as you’re playing through different music recordings. The SRC button gives you instant access to different resampling options (performed on a Cirrus Logic CS8422 chip): 16/44.1, 24/88.2, 24/96, 24/176.4, and 24/192. Very impressive indeed. One thing that we still have to take with these Chinese players is the slow response time from the time a button is pressed to the actual screen change. In this respect, the Colorfly is slower than Hifiman’s player. A big unconvenience, but I can still live with it. Another more annoying bugs that I’ve found with the Colorfly is that with .WAV files, everytime I change tracks, a screen prompt saying “Play Error” is displayed, although the playback is running just fine. This doesn’t happen with FLAC, but only with .WAV files.

    Have you used it with a good DAC? That is what the coaxial S/PDIF output is for. You could even use it with the Boomslang/Toucan combo to create a gigantic transportable rig. I love the wood on the player.

      Hi George,
      Yes I've used it with the Grace m902 DAC, as I mentioned on the article. 😀

      I think that with a player that costs close to $700, we expect it to have a good internal DAC. Otherwise you'll just buying a $700 transport.

  • Reply December 25, 2010

    George

    Yeah, you are right. For a transport, you could make it much lighter and smaller. However, having both analog and digital is good for a portable player because you can now use it directly with the JH audio JH3A which takes the coaxial inputs. But pretty much everyone who can justify this player probably has some kind of transport and home rig, so your point stands.

    I have a bad experience with the slider pot in the past time…

    due to the slider construction, there must be an opening on the front side of the pot slider… in my experience, this opening make dust more easily get into the tracking area (compared to the common turning type pot….) and thus after sometimes, I got crackling sound while slide the pot…

    hopefully the fly use the pot with good encapsulation…

    • Reply January 27, 2011

      Mike

      Good question.

      As I review more and more DACs, I realize that often people's set ups
      are not as ideal as a review set up. For instance, the HD800 is the most
      revealing headphone I have ever found for testing source quality and you
      also need to be playing *most likely* live recordings, whether
      audiophile recordings or classical recordings to get a true sense of the
      soundstage performance, ambiance and micro detail levels. Say if I'm
      playing a rock or electronic recordings, often the low level detail and
      the ambiance information is not there, so in the case of the HM-801 and
      the C4, with those recordings, perhaps the only thing that will come
      through is the different tonal balance. The C4 is brighter, and so that
      may come up as more detailed because of the treble presence. But if you
      take a HD800 and a live recording, then you'll notice that the HM-801
      has a far better ambiance, soundstage and micro details.

      For this reason, for some people who don't listen to a lot of live
      recordings, sound signature is more important than the actual DAC's
      resolution.

      Now, between the HM-602 and the Colorfly. Micro detail, ambiance, and
      soundstage depth is still better in the HM-602. But soundstage width is
      much wider on the Colorfly. The HM-602 is also warmer with an even more
      relaxed treble than the HM-801, so for some music, the Colorfly would be
      more lively on the treble.

    The hm-602 it’s very good with the hd 800 but I find than the synergy between the different composant is very important. For me, the hd 800 is too expensive (and I try with a shining amp and it’s not transcend for me and it’s for this I think the synergy is very important) and I want take the hd650.

    But the hd650 is very dark and the hm602 is very dark too, but the together isn’t risk to become too dark ?

    My dream installation is a hd650, hifiman hm602 (the hm801 it’s too expensive), the futur lisa l3, what do you think ?

    Thanks !

      Yes, I can see the HM602 going to be too warm and too dark for HD650.

      I would rather get the HD650, driven straight from the HM-801, and
      bypass the amp. The HM-801 is one of the most awesome pairing, direct to
      the HD800, and I don’t see it having problem driving the HD650 as well.

      With the HM-801, you also get more treble presence than the HM-602, and
      the DAC resolution is also very2 good.

        I see Lisa L3 have a V signature and the stephan cable makes brighter

          The Lisa 3 doesn’t have a V-signature, it’s actually the opposite which
          is a mid-centric signature.

          I would just get the HM-801, direct to the HD650 and not worry about the
          Lisa.

    The Colorfly 1/4 inch headphone jack is also the Line Out – variable up to 2v! It will also allow two sets of phones to be used. I have been testing the C4 for three months and am now using it as my main music source, far better than any CD player I’ve heard. So, my two CD players are now boxed up and my CD/ Record collection is stored safely on a 240 gig hard drive. It’s also great to be able to make high quality play lists on say a 2 gig MSD which the Colorfly also uses.
    In short, some of your comments are very ‘subjective’.

      Do you know that there are fundamental differences between a true line out and a true headphone out? So far I haven’t seen any devices that is able to combine the two into one.

      I am glad that you find the C4 to be very good. I think it’s a good player, but there are definitely better ones out there, even more CD players.

        Actually, the Centrance Dacport also combines the headphone out and line out. I still don’t think it would be as good as a pure line out though.

    The Colorfly does have line out. The 1/4 ” headphone jack is a true line out and will give about 2volts at maximum . Also, having used the C4 as my main music source for over three months I find that overall it is simply the best, my CD players are now no longer used and nor is my deck. Much of what has been written about the Colorfly is very subjective and many so called reviewers have only ‘played ‘ with it for a short time.
    A quote from another, well informed, user –
    “Overall I would rate the Colorfly as being the best music player because it sounded better with my ACS T1 custom IEMs, has a built in 1/4 inch jack output, it looks a lot nicer, comes with a nice carrying case, has slightly better software, has 32gb internal storage (the HiFiMan has no internal storage, only SD cards) and is also about £50 cheaper than the standard HiFiMan. Also bear in mind that my HiFiMan has the upgraded headphone amp module and a 32gb SD card so the total cost of my HiFiMan is about £800 compared to £550 for the Colorfly”.

    I would highly recommend the Colorfly to anyone.

    Hi. Sorry to bang on about the Colorfly but you say there are better players. I can’t find one with a better overall spec so far, perhaps you could suggest one? As for CD players, well I understand that all CD players are limited to about 20 – 20Kh and since I use only quality Flac/Wav files of 24bit/96 or 24/192 surely the Colorfly will sound better. At least I think it does. It seems to me that most folks are happy to spend a small fortune on players and headphones but are listening to mp3’s, so to my mind, a bit daft. Perhaps I’ve got it wrong? I have, only last weekend, seen the Colorfly being used in a Pro CD remastering setup by a very respected audio engineer.Surely that says it all!The only down side is that I can now instantly hear the difference between a good recording and a bad one and boy, there are plenty of those. Good music of any genre starts with a good recording and mastering and if you don’t have that, well, “you can’t make a silk purse out of a sows ear”!

    Cool review, question no one seems to be asking/answering though is just how portable is it with the slider volume design? Not only would it accumulate dust over time  but I think most would find it difficult not turning it up when putting it into a pocket and down when taking it out. Its a nice touch and all but theres a reason why buttons and tabs are popular.

      Yes, I suppose those are valid reasons, especially with concerns over
      the dust. However that doesn’t prevent people from getting the Colorfly.
      I think at this point the product segmentation is a bit different than
      the other DAPs. People who owns the Colorfly most probably has a good
      number of Ipods at home and want something unique and that sounds
      superior from the Ipod. If they’re going for a walk outside they can
      probably get the Ipod Shuffle/Nano, or the Sansa Clip+ as those are far
      more mobile than the Colorfly. The Colorfly is quite big and isn’t
      practical to take out.

        Hi. I disagree with you on portability to some extent. I often carry the Colorfly out, it fits very nicely into the same case as my Beyerdynamic T50’s along with an interconnect in case I end up at a friends house and want to plug it into a static system. Of course, if I were jogging I’d use my iPod and would be less concerned about sound quality.

      It’s hard to say cause the Colorfly gives you a superior DAC section, but the amplifier section won’t be as articulate as the pico slim.

      Still I would take a Colorfly > headphone over Iphone > Pico slim > headphone for sound quality simply because of the DAC section is so much better, and the amplifier section is also quite good. And if I was using the Colorfly as a portable player, I probably wouldn’t bother carrying an additional amp.

  • Reply August 6, 2011

    The CF does in fact play native Wav files in 24/96 and 24/192. It will only play Flac at 16/44 although a new firmware update is expected to enable higher res Flac file playback.
    I have never seen an error message on any of the CF”s sold so far. The only thing I can think of is that some Wav files e.g. some files offered by Naim are in BWF and contain metadata which until recently the CF could not play. This has now been resolved.

      Am I right in supposing that I can use my laptop with my HiFace 24/192 usb-coaxial converter and connect it to the Colorfly to use it for 24/192 files from my laptop?

      • Reply August 6, 2011

        Dave

        Sorry but you have lost me here. I do not own a Mac and reviews of the HiFace are not that good. Why would you want to do this anyway? The CF works just like a portable hard drive, you can simply drag and drop files into its internal memory or onto an SD card and off you go. Many folk download HiRes files from sites such as HD Tracks in anything from 16/44 to 24/192 onto their PC or Mac, convert to Wav if necessary and then, as I have said, drop them onto the CF. As a ‘stand alone’ player the internal DAC/Amp are very good indeed and if you want better then you can use the SPDIF out into any DAC or digital amp. Did you read the second review on Amazon? Fact is even 16/44 Wav files sound pretty good anyway on the CF providing they are good in the first place. I always use EAC for ripping from CDs and the results are often quite stunning. Plus you can upsample if you wish direct from the CF. Perhaps the main downside of the CF is that it is unforgiving of poor quality recordings, it tells it as it is!
        Hope this helps, many people do not seem familier with the CF and often post comments without substance. I am happy to answer any questions re this player as best and as honestly as I can. As a matter of interest how many people are aware that there is a facility in iTunes to convert to Wav? I wonder why?

          Actually the HiFace is very good, there is nothing else comparable at its price range. Of course there are better, but not similarly portable and cheap
          The advantage of using a laptop is that you can
          a. use a nicer interface / music library manager like jriver
          b. watch movies etc
          c. just choose any music to play immediately, rather than copying it across to the colorfly before being able to play it

            O.K. I see now and of course, all that can be done with a Windows PC too. The CF comes with a USB lead so that is all you need to transfer files from Laptop to CF. You can transfer any compatable file up to 24/192 wav. I guess you could also use your HiFace into the CF  S/PDIF in and use it as a DAC feeding into whatever. The photos on their web site show this I think. Forgive me if I am still missing something here 🙂

            Not that I want to buy, but I did a search for U2 and it didn’t find anything.
            Still haven’t found what I’m looking for- pardon the pun.

              Yes you can’t quite get mainstream recordings like U2 in 24bit yet.

          In addition to HDTracks, you can also get 24bit music from Bowers and Wilkins:

          Though the selection is normally quite limited to Audiophile and Classical, so can’t quite get mainstream music in 24bit, at least not yet.

            I think I’ll revisit this issue in a year or two – no substitute for CD and vinyl just yet (in my mind anyway).

        Just a thought…. the Zoom is a very good bit of kit indeed. I use one for making Wav files from vinyl via a decent phono amp. Playback quality is better than many portable players too and as good as some of the best. I had a listen to some recordings last night that I have made from my old albums, played back on my C4 and have to say, I’d forgotten just how good they are.  I think the Zoom is underestimated as a player or maybe just not even considered.

        So could someone please clarify: does the Colorfly play Flac in 24-bit 96KHZ as well as 24-bit 192KHZ, or must I convert these hi-end Flac files to WAVs?  I would have a hard time believing that a $800 player wouldn’t play 24-bit Flac. I realize that I can convert them the WAVs, but I don’t to have to spend extra time or diskspace doing this.

          With respect, if you took the time to read these posts you would see the answer was posted here only 3 days ago….. O.K. Lets clear up a few things here –  ‘ The Colorfly will only play WAV files up to 24/192. It will only play FLAC and other formats up to 16/44′. Not a problem for me as I firmly believe that native WAV files are better sounding than FLAC 16/44. I don’t wish to argue this point, after long trials over the last year or so I, at least, am convinced that FLAC is not truly lossless. Disc space is not an issue anymore either. I have a strong feeling that FLAC suits the providers and is not in the best interest of consumers such as myself. Yes WAV takes longer to download but so what? All just my personal opinion of course.
          As for the C4, $800 does seem like a lot, I live in the U.K. where it costs about £550, not cheap, but I still think good value considering it’s spec and don’t forget, the Hi FI Man 801 has no internal memory! I have two Colorflys’ now and have come to the conclusion that 16/44 WAV on this player is more than just ‘good enough’ providing you have good qulity files in the first place.

      Hi.

      I’m amazed that after some considerable time now the Colorfly C4 is still not fully understood. I have been using, testing and comparing the C4 to other players since last Christmas and now have two. I have also used the Colorfly with various DACs and Headamps.

      O.K. Lets clear up a few things here – The Colorfly will only play WAV files up to 24/192. It will only play FLAC and other formats up to 16/44. Not a problem.
      I firmly believe that native Wav files are the best option anyway, certainly not Flac and yes I know all about file size, again no problem.
      Like any player of this type you will only get the best results by using the best source i.e. The File/recording. There was a blurb on the QA site (refering to the QLS 350 that said ….. “only if you use files LOVINGLY extacted using EAC”. Quite right in my opinion. If you rip a CD with care using EAC correctly then the 16/44 Wav file will sound amazing on the Colorfly and in actual fact there is often not much to be gained by using files of 24/192. One can always upsample anyway and on playback I prefer to leave the Colorfly set at 24/96. The resolution is incredible through the right(?) headphones.

      I do have many higher res files, 24/96 and 24/192 but few give a noticably better result than 16/44. There are always exceptions to this of course and some have so much resolution I don’t always like them, too much detail!!

      There are other points I’d like to make.  The Colorfly is often unfairly compared to other set-ups that use various Players, DACs and Headamps. As a STAND ALONE unit the Colorfly is excellent and when one considers the cost, is also very good value. The HiFi Man 801 for example has no internal memory and also needs the upgraded headamp in order to compete, very costly!

      Perhaps the best advice I can give would be – it all starts with a good recording and how one creates a file. A good 16/44 WAV file of a good recording should satisfy anyone but the most difficult to please and if one has to listen so hard to hear a difference then they are not relaxing and enjoying the music. Remember, you only have to please yourself, not your mates (he doesn’t have ‘your’ ears anyway) and no need to impress anyone either. If your ‘whatever’ player gives you pleasure and gets your foot tapping then why change things?  THE LAW OF DIMINISHING RETURNS  is a curse on all things Hi Fi!!

      Looking back over  these posts I see I have answered some of these questions before so perhaps it would help if readers were to check out previous posts.

      Oh, and before anyone asks, NO the CK4 does not compare to the C4 in build quality and especially in audio/musical ability. They are aimed at totally different markets and as far as I know the CK4 is not yet licenced (mp4) for sale in the E.U. although it does appear on eBay U.K. from an obscure source in China.

        I’m going to hold off spending $800 on this player until it can play 24-bit Flac in at least 96KHZ. To me this is a major FAIL not to support 24-bit Flac. Until then I’ll stick with my $50 Fuze.

        Hi Dave,

        I came across your comment while searching for reviews on the Colorfly C4. I’m no audiophile yet but I have recently become interested in upgrading my music library with better sound quality starting by ripping the CD’s in the correct file format. It sounds like you really knoiw what you are talking about and if you are the type that likes to tyeach others I’m sure I could learn a thing or two from you. If you wouldnt mind mentoring someone please let me know if I could e-mail you directly for a follow up discussion. I can be reached at wiltz@videotron.ca   Thanks Allan

    “Actually digital playback has surpassed CD.”  Posted by Headphonia.What exactly do you mean here? A CD player is digital and anyway, the end result is always analogue. Do you base this idea on the fact that CD players are mechanical? Or, that digital files can hold a much higher bandwidth? Much of  which is beyond my hearing ability. I do have both systems, at times I prefer CD, other times I prefer what I think you mean by digital. They both please me but frankly, I prefer them both when ‘fed’ into a good valve amp (harmonics). I do not like  total silence between tracks, it’s not normal.

    “I think I’ll revisit this issue in a year or two – no substitute for CD and vinyl just yet (in my mind anyway).” Posted by Farhan.I used to think this too. I love vinyl, well at least the ‘sound’ and still prefer it to CD in many ways. However, we are talking portable devices here (C4) and therefore cannot compare them. Having said that, I have recordings made from my vinyl collection in both 16/44 and 24/96 Wav that are wonderful. When played back via my Colorfly or even a QLS 350 these recordings convey all that I love about vinyl. The surface noise, odd clicks and pops, warmth and of course detail. Especially when played back via my valve amps. The best part is that my vinyl collection is now safely stored away, no risk of damage, I have sold my deck for a very good price and I have recovered a lot of ‘space’. Can I just add that the process of recording is a real pain. Apart from anything else one has to do this in ‘real time’ using a decent phono amp and of course a recording device e.g. Zoom.Strange, but must confess to missing the pleasure/pain of using vinyl sometimes. Just nostalgia.

      Yes I love vinyl, I just don’t think they blend too well with headphones due to the pops and clicks (and headphones tend to zoom in on those pops and clicks). Vinyl just sound so much better with speakers.

    The posts here are all well and good, interesting and thought provoking but (and including some of mine) are tending to go off topic – Colorfly C4. Am I alone here, does anyone else have the C4? I’d like to read the thoughts and comments from at least one or two other users of this player.
    In the meantime here’s a question. Is it realy worth worrying about higher resolutions than 16/44 especially on a portable device ? How many can honestly hear a difference anyway (loads of blind tests only give a 50/50 result at best – much like tossing a coin). And another, am I the only person here who can hear a difference between Wav and Flac?

      Okay,
      I’ve only had the C4 for the period of the review so you probably know more about it now than I do. But on the topic of Wav and FLAC, I’ve heard more than one people say that WAV gives you a weightier sound.

      I’ve purchased two iPods. One was the 160GB classic. It was reviewed as a good performer. Within a couple minutes I had clearly decided it was missing presence, sound stage. The sound was basically flat and tinny compared to my old Creative Zen 60.  I promptly returned it to Future shop.

      Fastforward ~2years. I bought an iPod Touch 4g 32GB. I was blinded by Apps, Wifi and more tools than I could shake a stick at. WONDERFUL device. Loved the interface! As the night neared its end, I remembered that I had purchased a music player.  Transferred some loss less recordings to it and plugged in my Shure SE500’s.

      I shit you not, 15 seconds flat, I heard the worst garbage amplifier ever. I ripped the headphones off and threw them in disgust.  Nothing wrong with the player I’m certain, it’s just that I expect a heck of a lot better from a “Music Player”. I couldn’t stomach it.
      Returned it today.  Apple makes crap portable audio and that’s all there is to it.

      So as you say, can you hear 16/44 vs 24/96 or 24/192? How the fuck can you not?  I have year to actually hear acceptable portable audio. I’m still searching.  Hoping products like these will deliver.

    At long last the CK4 I ordered has arrived. First impression… not good, it rattles like hell !
    The seller says that this is normal, all CK4s’ rattle ????? WHAT!  O.K. anyone here know how to open it up without damaging it? I think it could be the battery. Sounds o.k. but not up to my C4, no S/PDIF but then I did know this before buying, battery life seems fine (so far about 8hrs).
    In short, not fair to compare with C4 but maybe value for money, mass market product that might appeal to those on a tight budget and who are happy with mp3, 8gig not nearly enough for quality Wav files in 24/192 ! Or even 24/96 ! Can’t really see the point on a machine like this, bit of a gimick, sales point I guess.  I shall do some long term tests and comparisons. Probably end up selling it on – anyone interested?

      That’s what I’ve heard on the CK4 too, not quite the same audiophile-grade player as the C4.

        Glad you agree. In fact after listening some  more today with my T50s’ not even sure I like the sound. Early days, but to be fair a big difference in price and for those who want MP4  maybe a good buy. Having said that, not if they rattle about like mine does! I think/almost hope the seller in my case is full of bull s**t. I’ll email Colorful in a day or so and see what they have to say. Perhaps this player will at least stir up the market a bit. A challenge to the god that is Apple? Very brave and good luck to Colorful, the C4 has opened up a whole new world of pleasure for me and I for one am grateful for that.

      Hi Victor,
      A few friends of mine has the DX100 and I’ve used it on a few occasions.

      UI wise, I think this is the most complete, most mature audiophile player so far. Likewise on build quality.

      Sound wise, I don’t think it’s quite up there with the HM-801 and Tera Player. But again Hifiman is our sponsor, so..

      Full review, I don’t have a plan for it, but if you have any questions you’re free to ask.

      Headphone out is incredibly powerful, BTW. I was able to drive the HE-6 though at maximum volume level and gain.

      I’m using it right now. The so called HD650 veil isn’t there at all and the Theorem makes the HD650 less warm. Pace is good. Bass isn’t that big. very clear and airy sound. The HD650 clearly misses the tubes.

      It’s an ok combo but not the best of synergy

          The best is still the HM-801. It’s just that it’s big and not so sexy.
          The AK100 is the one I’d go for.
