Hello Everyone,
This is a review and detailed measurements of the Fiio DM13 portable CD player.
!!!EDIT 9 Sept 2026!!!: @FIIO Official provided me with a new firmware and it resolves many of the issues I reported a year and half ago. I updated this review accordingly, leaving the old text Strike-Through and updating in blue.
Fiio DM13 - Presentation
I'm not sure I need to provide an extensive presentation as everything is available on the vendor's website. In a nutshell, this is a portable CD player that plays on batteries and be used to rip your CDs too.
The one I got is the non-bluetooth version, and I like the fact it offers unbalanced and balanced outputs, as well as a digital one via a a single 3.5mm jack output. Note that a 3.5mm to RCA coax converter is provided and you'll need to buy another one if you want to use the optical out.
I bought a 4.4mm to 3.5mm balanced cable from Fiio, to perform the below measurements.
I must admit it was real fun to be back to use a pseudo "Discman". That reminded me of when I was young. I could appreciate a good resistance to shocks. I had pleasure listening to it and I could not spot obvious flaws.
User experience
This player is relatively fast to skip one or multiple tracks and offers a FFW/REW function, a little slow but really usable.
The batteries lasted 10 hours, as advertised, during my tests. It also stayed very cool even after long hours of playing. This is good to know if you intend to use it when travelling/walking as you can keep it in a bag without any problem.
I listened to it using the 7Hz x Crinacle Zero:2 IEM, and was nothing else but pleased. Besides my beloved Pink-Floyd - Delicate Sound Of Thunder, I also had great pleasure using the CD layer of the SACD Josef Suk - Asrael Symphony, Malaysian Philharmonic Orchestra, Claud Peter Flor.
Note that the DM13 is gapless playback but it does not apply de-emphasis when required.
Fiio DM13 - Measurement (Analog out)
All measurements performed with an E1DA Cosmos ADCiso (grade 0), and the Cosmos Scaler (100kohms from unbalanced input) for analog outputs, and a Motu UltraLite Mk5 for digital.
I performed all measurements as I described them in the post “More than we hear”, and as I reported them for the Onkyo C-733 review. Over time, this will help comparing the devices I reviewed.
The Fiio DM13 outputs a high 5Vrsm from balanced outputs (I did not test unbalanced). There was a slight channel imbalance of 0.17dB which is decent. The balanced outputs are noninverting.
All the below measurements are from balanced output with volume down to 4.2Vrms, to kind of align with Amir's standard. But the measurements are the same at full 5Vrms output, it made no differences.
Let's start with the standard 999.91Hz sine @0dBFS (without dither) from the test CD:
The Fiio DM13 does a little better than its published specs with 0.0015% of THD+N (0.002% published). The resolution is indeed 16bits.
That said, note these spikes of odd harmonics (H3, H5, H7, ...). That reminded me of some issue we already discussed here when trying the burn a test CD with Windows Media Player. The distorsion you see here does not look like coming from the conversion itself... So, let's investigate.
This is the new measurement with Firmware V17:
Note that all artifacts of distortion due to heavy signal processing vanished. This is very good news as we are now very close to the digital file. For a trully portable device, this is exceptional results that many high-end CD Players would like to achieve.
----
I usually add the same measurement at -6dBFS:
Ah, again the same distorsion profile (odd harmonics slowly decreasing) at a lower level too, that is very uncommon. With this, we can suspect a digital change of the signal prior to conversion, some sort of level equalization as we saw with WMP. Using shaped dither, we can lower the noise floor to analyze deeper.
Again no unwanted distortion anymore, this is again very close to the digital file as recorded on the test CD.
Below is the same 999.91Hz @0dBFS but with shaped dither (hence the double wave of low level noise you see starting at 6kHz):
Well, here we reveal an effect of processing the digital signal before conversion. Too bad because I think otherwise the DAC in use here is very good (unless this is a function of it, but I doubt).
As you can see above, with the V17 firmware, and one more time, all that distortion from digital processing is now gone, good news!
----
Let's park this issue for the moment and move on to the good news. First, this is an very silent player:
The above view is better than before, and the typical 3 small grouped spikes are quantization noise (digital) not from the DM13 and that means we have here a high resolution CD Player.
No visible components from mains, this is perfect and too rare.You might argue with the previous view that was showing a 50Hz spike, but that was my error, the PC in use for measurements was not on batteries and I got lazy to run the measurement again, sorry.
----
Let's continue with the good news as the bandwidth is very flat:
You can see the channel mismatch (0.17dB) which is not a concern. The roll off at the end is an effect of the oversampling filter in use.
----
Talking oversampling filter, this is how it works:
The filter attenuates by a good -90dB. We see significant noise shaping in action here, an effect of the delta-sigma converter.
Note I ran the same with the V17 firmware, and we see less low level distortion from the dual tones:
----
Multitone (1/10 decade) shows a happy CD player, not having issue to clear 16bits of data:
No improvements with the new firmware here, but it was already very good.
----
The Jitter test is relatively good:
We can see some unwanted artifacts but they will remain hidden into music.
No improvements with the new firmware here.
----
Started with the Teac VRDS-20 review, and on your request + support to get it done (more here), I'm adding an "intersample-overs" test which intends to identify the behavior of the digital filtering and DAC when it come to process near clipping signals. Because of the oversampling, there might be interpolated data that go above 0dBFS and would saturate (clip) the DAC and therefore the output. And this effect shows through distorsion (THD+N measurement up to 96kHz):
I kept some references and will keep the same for other reviews, so you can quickly compare. The results of the Fiio DM13 mean the oversampling filter has 3dB+ headroom when outputting 4Vrms. This is very good but means there is digital attenuation. That said, even a full output (5Vrms), there is still 2dB headroom. So I would again suspect the presence of an SRC used to perform digital attenuation, or something equivalent. For once I've put in parenthesis the THD (without noise) because the noise shaping is added into the calculation and would look like beginning of clipping but it's not.
The above very good resistance probably comes from the digital processing prior to feed the DAC and that reduces the level by -6.02dBFS. See later below the Digital output tests.
----
As I did with the Sony CDP-597, I add a "max DAC resolution" measurement test. It is performed from a 999.91Hz sine @-12dBFS with shape dither (from Audacity). I restrict the THD+N span to 20Hz - 6kHz in REW not to account for the noise of the shape dither beyond 6kHz. I take the calculated ENOB and simply add 2bits to it (due to the -12dB attenuation, as 1bits=6dB). The potential maximum, when calculated from the digital WAV file, is 18.7bits under this test. A "transparent" DAC should achieve 18.7bits, ie 100% in this test.
Here are the results compared to others:
Hey, let the Fiio DM13 enter the top of that ranking! This is the proof again that indeed its DAC is truly high-res.
----
Stereophile was often using the 3DC measurement as a prof of low noise DAC. It is from an undithered 997Hz sine at -90.31dBFS. With 16bits, the signal should appear (on a scope) as the 3DC levels of the smallest symmetrical sign magnitude digital signal. Here is the result with the DM13:
Houston, we have a problem. What we see here is asymmetry of the output that I've never seen before. This view means the output is far from the requested -90.31dBFS, and actually I measured it at -95.37dBFS. So that is a lack of linearity by 5dB, and that is huge. It does not get much better if I set the output at 5Vrms because the deviation is still a massive 4dB!
Fact is the DM13 looses linearity as early as -70dBFS (by 0.7dB), while we are used to see linearity nailed down to -120dBFS these days! This is equivalent to what I saw with the Marantz CD-73, which had a 14bits DAC. So this is really bad results for the DM13.
So we have the culprit here, I believe. There is processing of the signal which deteriorates it at low levels and that is too bad.
All of it fixed now:
Other measurements (not shown):
Note that the player does not apply de-emphasis filter if needed,
Fiio DM23 - Testing the drive
What would be good measurements if the drive would not properly read a slightly scratched CD, or one that was created at the limits of the norm? The below tests reply to these questions.
The drive was able to consistently continue playing, and without generating typical digital clicks, with dropouts of up to 3mm. The interpolation effect remained hidden to my hears when it kicked-off and the DM13 did not fail to maintain a constant flow with up to 4mm dropouts. It is the maximum I can measure, so that is near perfection. The Fiio had no issue with variable linear velocity and/or track pitch, as well as with HF detection. This is a crazy good drive!
Fiio DM13 - Measurements (Optical Out)
I've seen several of you reviewing CD players using their digital outputs, in case the results could be improved from an external DAC.
This is the 999.91Hz test tone @0dBFS:
We find again the distorsion we already saw, with a set of odd harmonics that are not on the test CD. This means there is digital modification also with the digital output. This is not "bit perfect" by far.
This is the updated measurement with firmware V17:
Qs opposed to before, no digital processing here. This is the same as the original digital file. The noise floor and very little spikes are due to the quantization errors, ie rounding errors in 16bits, nothing more.
By the way, our 3DC levels are also impacted, this is again asymmetry and therefore lack of linearity in the digital domain:
I never saw that before. This drives me to believe there is processing before the signal reaches the DAC and also before it reaches the output. What for? I don't know, but this is too bad, even if I could not hear any negative impact. I guess there is some resampling via an ASRC or something because the player has also a Bluetooth option (well, not mine) and maybe that's to simplify the processing downstream. Again I don't know, but it's not good.
This is the updated view with firmware V17:
No linearity issue anymore, this is the wanted signal.
EDIT: I did not think before about running the below test, due to the imprecision of the clock. But this is a bandwidth analysis from periodic white noise done with 600+ averages and smoothed. It provides an interesting result (Linear Frequency Scale from 20Hz to 20kHz):
I compared with a CD Player, the Denon DCD-3560, both from their digital outputs (optical). The Denon (purple trace) shows what we expect, a straight line in digital domain. But the Fiio (blue trace) exhibits the typical ringing of a low resolution digital filter. This is what we had more than 40 years ago, with the first 2x oversampling digital filters. This means there's an interpolator, most probably a sample rate convertor, performing a resampling (even if it is resampling from 44.1kHz to 44.1khz) in band limited, of the digital signal, and prior to send it to the digital output. This is not desired.
The above is resolved now. But let me take the opportunity to update the review with intersample overs test at 5512.50Hz, with a phase shift of 67.5°, like I did for the TASCAM CD-200 review. This signal generates an overshoot of +0.69dB. And so, if the signal would be modified before being sent (by an ASRC for instance), it would show either a reduction of amplitude or we'd see some sort of saturation/increase of noise/distorsion. So, here we go:
No distortion here and we get the expected +0.69dBFS meaning again no digital modification of the signal. In other words, this is a perfect transport.
Conclusion
The Fiio DM13 is extremely good at reading a scratched CD and following a track without failing. It's one of the best I measured in that area.
It is therefore too bad to see such digital processing and degradation of the signal. I think this is a software error and I hope a firmware can fix that. I will update if that's the case. -->> Fiio did it!
In the meantime, I can't say the flaws shown can be heard. They remained hidden to my hears. But this little player missed a very high mark because of some undesired processing. Too bad.
I left a message on Fiio’s forum to request if it’s ok to use their recent firmware update which theoretically applies only to the Bluetooth version. If they confirm, I’ll update and cross my fingers that it solves this processing issue.
Obviously Fiio heard about the concern, fixed it and contacted me to test the latest firmware. I can confirm all concerns are gone now. The fact that the digital output is now "bit perfect" is also a great improvement with that new firmware.
I must say I am very happy to see a vendor following up as such, with the desire to improve the product at 0 cost for the customer. Nice!
And with all of that, the Fiio DM13 becomes one of the best CD Player I measured!
Cheers
PS: Message to Fiio engineering: Please fix that software error with digital attenuation calculation, and you have one of the best CD Player/Transport (besides clock precision, but that will be for the next iteration/super high-end version of this player). Pretty please?

Fiio DM23 - Testing the drive
What would be good measurements if the drive would not properly read a slightly scratched CD, or one that was created at the limits of the norm? The below tests reply to these questions.
| Test type | Technical test | Results |
| Variation of linear cutting velocity | From 1.20m/s to 1.40m/s | Pass |
| Variation of track pitch | From 1.5µm to 1.7µm | Pass |
| Combined variations of track pitch and velocity | From 1.20m/s & 1.5µm to 1.40m/s & 1.7µm | Pass |
| HF detection (asymmetry pitch/flat ratio) | Variation from 2% to 18% | Pass |
| Dropouts resistance | From 0.05mm (0.038ms) to 4mm (3.080ms) | Up to 3mm. |
| Combined dropouts and smallest pitch | From 1.5µm & 1mm to 1.5µm & 2.4mm | Pass |
| Successive dropouts | From 2x0.1mm to 2x3mm | Pass |
The drive was able to consistently continue playing, and without generating typical digital clicks, with dropouts of up to 3mm. The interpolation effect remained hidden to my hears when it kicked-off and the DM13 did not fail to maintain a constant flow with up to 4mm dropouts. It is the maximum I can measure, so that is near perfection. The Fiio had no issue with variable linear velocity and/or track pitch, as well as with HF detection. This is a crazy good drive!
Fiio DM13 - Measurements (Optical Out)
I've seen several of you reviewing CD players using their digital outputs, in case the results could be improved from an external DAC.
This is the 999.91Hz test tone @0dBFS:
This is the updated measurement with firmware V17:
Qs opposed to before, no digital processing here. This is the same as the original digital file. The noise floor and very little spikes are due to the quantization errors, ie rounding errors in 16bits, nothing more.
This is the updated view with firmware V17:
No linearity issue anymore, this is the wanted signal.
The above is resolved now. But let me take the opportunity to update the review with intersample overs test at 5512.50Hz, with a phase shift of 67.5°, like I did for the TASCAM CD-200 review. This signal generates an overshoot of +0.69dB. And so, if the signal would be modified before being sent (by an ASRC for instance), it would show either a reduction of amplitude or we'd see some sort of saturation/increase of noise/distorsion. So, here we go:
No distortion here and we get the expected +0.69dBFS meaning again no digital modification of the signal. In other words, this is a perfect transport.
Conclusion
The Fiio DM13 is extremely good at reading a scratched CD and following a track without failing. It's one of the best I measured in that area.
I left a message on Fiio’s forum to request if it’s ok to use their recent firmware update which theoretically applies only to the Bluetooth version. If they confirm, I’ll update and cross my fingers that it solves this processing issue.
Obviously Fiio heard about the concern, fixed it and contacted me to test the latest firmware. I can confirm all concerns are gone now. The fact that the digital output is now "bit perfect" is also a great improvement with that new firmware.
I must say I am very happy to see a vendor following up as such, with the desire to improve the product at 0 cost for the customer. Nice!
And with all of that, the Fiio DM13 becomes one of the best CD Player I measured!
