“I feel synchronized with the reality of time” is such a perfect assessment of that experience. Especially growing up with that sound, I understand!Awesome video 🙌🏾
Hey mate, nice review! Long pressing the knob (~5 sec) turns the device on/off, there is no dedicated power button but the interface gives full control. Double tapping the power knob also gives a quick switch between line output and headphone output. My favourite music for testing are: Paranoid Android - Radiohead, Drive - Incubus, Happy Returns - Steven Wilson, Stan - Eminem, Main Theme from Interstellar and the High Res remasters of Dark Side of The Moon and Led Zeppelin IV!
Daymn.... this is what product reviews should be like. Keep up the good work! One small niggle... UAC1 and UAC2 .... Some devices like playstation and older computers do not support UAC2 so you have no choice but UAC1. In this case the device might not recognize the DAC if it's set to UAC2.
Try to get a CD player with PCM-61 or PCM-63, and you will hear the R2R the way it supposed to sound. Better, if you can find an older player with PCM1704-K, that's amazing sounding. Denon DVD-6000 has two of them and has a digital input to be used as a DAC.
my r2r dac modules sound more magical, deep soundstage,micro details. but the power supplys cost around 1K.(plus the regenerative power)Fiio do the job very very good!!!im just listen 300 hours , and i like it.For that price?OMG!!!
Just placed the order and saw your video afterwards :) Excellent review! Really appreciate the explanation from an engineer’s perspective 🙏🏻 Question… will this DAC pair well with OTL tube amps?
Qudelix 5k has a battery. Nice review. This is the least expensive R2R DAC/amp available. Driving $1100-1500 USD headphones with $160 USD DAC/amp? Not sure. Unless you are under 40 years old or a dog almost no one can hear 16 kh anymore. Also...not to nitpick but the type of DS chip used is only one part of how a DAC will sound. Quality of parts, analog output stage, etc.
Dave, I mentioned the dog's hearing when recording the video, but I cut it off while editing it because I spent almost two minutes talking about it. 🤣 I said something like this: "People, a dog can hear at almost 45kHz. So if your dog runs away when you listen to music, something is wrong with your gear (at least in the high frequencies)."
Tiro o chapéu pra tua dedicação na produção desse vídeo. 👍 Tô com esse amp há 1 mês e continuo procurando o tal "som R2R". 😂 Me dá uma preguiça danada só de pensar em "volume matching" e fazer um A/B direto com outro DAC. De todo o modo, não posso me queixar -- pois pelo pacote -- é um baita ampzinho de mesa e até agora não presenciei nada de errado nele.
Obrigado Fabio! A ideia deste canal é ter videos sempre nesse nível. Quanto à comparação de DACs, a diferença mais perceptível vai ser nas Sub-baixas e baixas frequências 😉
Great review format. The video editing, back and forth, cut, cut, was disturbing, however. I have a long attention span, the result of decades of practice. I had to look away.
Of course I gave you my like! Very impressive review of this interesting DAC. I was aware of this device a few days ago. Is this a new launching from Fiio this 2024? Another thing I heard about is that cannot do native DSD. Saludos desde Buenos Aires hermano Brasileño!
¡Hola, hermano! Yes, it's a recent Fiio launch. And it seems to be selling well because retailers' delivery times are always changing. It does play DSD music, but it transforms the DSD information to be played at a frequency much lower than the DSD standard, which needs some MHz to be played directly.
Got mine a few days ago. It has some kind of remarkable characteristic that's hard to explain? Like music just feels more "real" which sounds ridiculous?
The R2R is not the last word in bass detail, it does lack a little pinpoint definition in the low frequency's BUT the vocals are very natural sounding and the treble is easy on the ears and that's probably the attractive quality of the R2R. I have both of the Fiio dacs, K11 DS and K11 R2R and the R2R vocals are more human, less digital but compare the R2R to the dac in my SMSL AO-300 (Cirrus Logic CS43131) and it cannot match the definition of the low frequency's. I would highly recommend the SMSL AO-300 to anyone looking for a very good all in one unit with exceptional sound quality and power.
@@theonlyegg ….very flexible! The presets are very well tuned imo. The ‘Tone’ leaves everything up to you so you can’t lose. Better than any tone control on any current £500+ class A/b amp, far better, much more accurate to the actual frequency being tuned rather than the smear that most amps will give you under £1000, could not say what goes on above that price.
Bought a k11 r2r, paired it with an also recently purchased Hfiman Sundara and I'm quite disappointed. Using Deezer lossless and Flacs for music yet I sense much distortion in the highs and it just sounds so grainy. I've an old KA3 dongle, also from Fiio and even that sounds warmer and cleaner. Anyway, my question, should anyone have any experience wit this combo is: have I perhaps received a defective product, be it headphone or DAC, or do they just work this poorly together?
Hi, you also need to test this DAC with this headphone using an external amplifier. The problem may lie in the combination of the K11's integrated amplifier and this headphone. I don't have a magnetic planar headphone to compare it with. As soon as I do, I'll make a video about it.
Another try is to use a balanced cable to get more power from the K11 R2R. Here is an option if you haven't a balanced cable yet: s.click.aliexpress.com/e/_Dl4YjnN
Always best to wait for the excitement to die down. I have the R2R and personally I would not rate it as high as 90% of you tube and online reviewers have. My SMSL AO-300 is far more capable of recovering low end detail for a start but I have to say I do like the vocal reproduction of the K11 R2R.
@@Panslapper Vocal reproduction was indeed decent for the price but it was heavily counterbalanced, with the Sundaras, by a noticeable lack of bass and the aforementioned distortion issue on higher frequencies. I've since tested the headphones on a proper integrated amp with a decent headphone out socket and they sound very well with pretty impressive bass for an open headset, so I know that the issue was indeed the K11, I managed to return it for a full refund and just ordered a Hifiman EF500 instead. Since I can't realistically test the products before buying them, basic dummy science suggests that a higher class device from the same company as my headphones might pair better. Just waiting on delivery now...
I’m actually selling my mojo 2 to purchase this unit. I don’t use the headphone out, I use it as a line out to external headphone amplifier. I just find it a little too clean. It’s a great sound, don’t get me wrong but after owning it for about a year now I just find it too clinical. Still, it’s noticeably better sounding than any delta sigma dac I’ve heard thus far.
Hi! Thx for video. I got the K11 and i know everybody has different hearing and liking. Can you suggest me what is the best filter for using it? 1) Minimum phase fast roll-off filter 2) Fast roll-off, Phase-compensated filter 3) Minimum phase slow roll-off filter 4) Slow roll-off, Phase-compensated filter 5) Wideband flatness filter 6) Non over-sampling filter
Option 3 is the most “natural” filter and will be the best option for most types of music. Option 1 or 2 may be the best transient response for electronic music and some new Pop music because those genres contain many “digital” sounds.
Lovely sound ..but had received a defective product from seller Headphone Zone India. Seller turned up unethical and never replaced it. Apparently this kept disconnecting my FIIO m11s repeatedly.
I can tell you about that item after checking the specs: it has an “OK”sigma-delta chip DAC (not so good, not too bad), but the problem is the amplifier: less than 150mW for 32Ohms is too weak for a Headphone Amplifier. The Fiio K11 version (without R2R) would be a better investment.
Great review dude. I have a fiio ka17 dongle which has a separate isolated usb C in for power only. This allows you to run a clean usb supply. The ka17 is surprisingly powerful. Check it out. It might make a good review vid for you xx
i belong to the "un-pure" audiophile group as i run everything into an eq. no apologies but every piece of recorded music is engineered and mixed differently so your sound system will always reproduce this. i prefer the sound that my ears say sounds good and that typically requires an eq. just how i do it.
I think the best definition of "audiophile" is: a person who invests time and knowledge in modifying music to get the best possible sound experience from it. And in that case you would be a purist audiophile 😄
I just used that song with "Hiss noise" because the Hiss is at a volume level below most parts of the music. That Hiss is over the whole frequency range. Because of that, some Sigma Delta DAC Chips will try to filter the song, but the filtering will not remove only the hiss. A DAC that filters our music is not what we want. That was the reason for the test.
I had one exactly like that. It worked well for just two years, and I never got around to fixing it. But it was the first amazing noise cancelling MP3 player I heard.
The best capacitors for audio signals are film capacitors. There are SMD versions, but they are too expensive to use in the Dongle DACs. If you want to filter the noise in the USB supply voltage, you need to add more components beyond electrolytic capacitors. Because that, it's cheaper to add an external power supply input.
@@tapedacI would love to hear your explanation on how Chord Mojo 2 works as I understand from Rob Watts it is totally different. I listened to a few podcasts but didn’t understand it.
@@LencoTB I got a mojo1. It's not meant to be a desktop DAC. If you do that it will overheat and kill the battery. Charge it or use it not both at the same time. The DAC part is great, the DC part and charging was an afterthought and mojo weak point.
This fiio r2r dac has an RCA output port and a headphone output port. I want to listen to music, connect the jack wire to the RCA port down to the amplifiers, sing karaoke at the headphone output port, connect the jack wire to the mixer then connect it down to the amplifiers, is this setup ok?
I want the RCA output port to connect to the amplifier to listen to music, and the 3 coxial output ports and output 6.5 or 3.5 to connect to the mixer down to the amplifier to sing karaoke.
im high end audio engineer, and i know R2R . Analog and digital stages must be perfect isolated, and noise regulated.i do this job today, and the sound just...........no words
No, no. There are two different DACs from Fiio with the same chassis and similar names: "K11" (Sigma Delta chip) and this one in the video "K11 R2R" (that uses a lot of discrete components instead a integrated chip). Thanks a lot ;)
Thank you for the review and the explanation on R2R as I had not heard it explained. I have been looking at getting the original K11 for IEM use (IE600) for my desktop and had read that the R2R version was coming out. In your opinion would there be any difference between the 2 and which would you say would be ideal. I do not know too much about audio gear so it is all a bit confusing.
As a K11 owner I tried the R2R version at London CanJam last July. And for music listening the K11 R2R is on par with £500/£600 sigma-delta DACs in terms of dynamics and quality. The regular K11 is too cold and analytic and misses a lot of quality around bass frequency reproduction and mid-bass dynamics (which is typical of the Cirrus Logic chip that uses). I would suggest you to try the K11 R2R unless your main focus is gaming, where the sound might feel congested with the R2R.
I think @or1on89 (🙃) already responded to you. So, if you equalize the K11 R2R as I described in the video, you can get a sound more balanced than the sound of any Sigma-Delta Chip. Regarding IEM phones, I need to make a video about them because there is a "small universe" of specific technologies and physics related to them.
Never use NOS mode unless upsampling the source (e.g: 44.1kHz to 384kHz) in order to test different resampler qualities and types. Otherwise it defies the logic of the sound reproduction.
@@heatnup NOS means you don't use any digital filter... without this filter you can't reconstruct the actual audio signal and you feed your audio gear with high frequency noise... this concept defies the logic of the sound reproduction.
