From 2013 onward, I began a systematic survey of FFT measurements published by some German Hi-Fi magazines. Those magazines belong to a publisher which runs its own laboratory, thus ensuring consistency in the measurement method.

At that time, I was driven by sheer curiosity. My goal was to establish an objective hierarchy among digital sources the best I could. Though informative FFT-based analysis is to assess the behavior of a particular device, it was indeed practically impossible to compare multiple devices between them. In time, there were no such thing as Audiosciencereview and I was left with no other choice to do my homework the old way. I then decided to compute manually the total harmonic distortion over the first significant harmonics of each device read on the FFT in order to rank the digital sources tested by the aforementioned magazines.

Obviously, the result of this work is by no mean a complete nor even sufficient way of assessing the performances of digital devices. Neither is this survey a product of absolute accuracy. The best I could do is a +/- 1 dB accuracy for each harmonics. Nevertheless, I think that this survey as been useful for me to have a glimpse over the evolution of digital techniques for home audio over a 30 years span and to make interesting observations (more of that latter).

You will find below the pdf files of two tables translated in English from their respective French originals. The first table lists a total of 850 devices by chronological order. In the second table, these devices are ranked by the level of their respective THD.

For the French speakers among you, here is a link towards a publication of the original French tables : https://cabasse.vraiforum.com/t6078-40-annees-de-mesures-de-distorsions-de-sources-numeriques.htm

In the following message, you will find the complete list of all devices which are part of this survey.

Great work! Since this includes a rare collection of SACD measurements from test discs, I am happy to see that the Marantz SA-10 is a step ahead of the “classics”

Thank you. I wish to point out that the German magazines I refer to cease to publish explicit measurements obtain with SA-CD test-disc at the beginning of the 2010s and that the SA-10 was tested in DAC mode, that is to say with the digital generator of the Audio Precision.

That measurement is mine and done with this demo disc

In DSD64 DAC mode, this is what the measurement was

Thanks.

I myself have this Denon demo SA-CD. Handy to set up a multichannel Hi-Fi installation. :)

It should be said that the pure sinus tones on this disc are at -16 dB (in DSD as well as in PCM) under max level. Thus, SINAD or THD+N measured with this disc (first picture posted by GXAlan) are not comparable with measurements made at or closer to 0 dB (second picture posted by GXAlan).

What is the voltage level at which theae devices are tested? Could you pleaee post an Excel file?
 
The actual voltage levels are not documented by the magazines. All measurements at 0 dBFS (or 0 dB SA-CD) digital input, hence at maximum output voltage, whatever it is, of any particular device.

As for an Excel file, I'm not familiar with this particular software. I have worked under Libre Office (Ubuntu distro). Will the original .odt working files do ?

This makes the results uncomparable unless you can find more details about the setup.

odt can be converted to csv, so that's fine.
 
I have re-uploaded the pdf file with the ranking by THD, because I discovered a device was missing in the table.
 
@Scytales kindly sent me the .odt files. They are document files rather than spreadsheets.

@Scytales if you move this data to a spreadsheet you will be able to list everything on a single page, filter and rerank as you like. I recommend learning to use Excel, Google Sheets or the equivalent in Ubuntu.

For example you can list and then rank and filter at will all of your various information with these columns (and maybe a few more depending on your needs):
IssueBrandModelNoteDACH2...THDUnitsTest Hz

The lists have both dBV (where 0dBV = 1V) and dBr, which is relative to an unstated reference level. Furthermore some tests are at 1kHz while others are at 315Hz or 330Hz. @Scytales did a good job noting this.

A fundamental problem with limited tests like this is that it is unclear to what extent ground loops or saturation (clipping) or other instrumentation issues play a role in the bad results. The other main problem is that the noise level is unknown, which is far more important.

Compare these results to those measured by @amirm: https://www.audiosciencereview.com/...measurements-of-cambridge-dacmagic-plus.6887/

Thanks for posting. Some people may be able to compare their older models to newer ones on the market, keeping the above limitations in mind.
 
Thank you for your comments.

It may well be possible to improve the data tables.

For a time, I also listed the noise-floor visible on the FFT and the harmonics up the 10th, but the work was much to heavy and not worth it (at least as far as THD is concerned, because higher order harmonics at much reduced level that the first 5 do not contribute significantly to the THD). My intention was never to list noise (or other apparent spurious tones), because it was impossible to figure out an approximate let alone precise noise level contribution from an FFT graph without further information. Hence the choice to list THD and not THD+N. Those tables are only a way to roughly evaluate the output linearity of each device at maximum digital input level.

I think the limited utility of this tables becomes apparent only when you look at them as a closed system, without trying to compare the data to other third parties measurements. I view them essentially as a record of the past, in order to have an idea of the evolution of digital devices over a relatively long time period thanks to an homogeneous cohort of data over said time period.

However, comparison with other measurements might be possible while keeping in mind the limitations you rightly pointed out. For example, I check the German FFT and H data I listed about the Marantz SA-10 and they correlate very well with Amirm's measurements of the RCA output of the same device. Same when comparing the data about the Marantz SACD30n to Vintageflanker's measurements of the same device. The differences are well within plain sample to sample item variation. The example you just gave about the Cambridge DACMagic is a good illustration of the very close proximity between the data coming from Testlab and Amirm's measurements of this particular device.

On the other hand, it is right that there are obvious discrepancies concerning other devices. For example the Sony NW-A105 appears much better in Amirm's review than in the Stereoplay review. When I checked in the actual printed review, I found that the output level was measured at 0.3 V RMS on 32Ω and 300Ω by Testlab, whereas Amirm measured 0.9 V RMS on 600Ω load. Clearly, that is different conditions. So, caution must be exercised when comparing data.

Overall, there is very little overlap between the devices tested on Audiosciencereview and the devices listed in my tables, devices which are for the most of them much older than those tested on Audioscience. Then again, I think it is better to view the tables I have uploaded more as a window open over the past than on our current time, when much more versatile measurements can be found on Audioscience or comparable resources.

I fully agree with you, and especially this comment.
 
Bearing in mind the intrinsic limits of the survey, here are some thoughts it inspired me.

1. Already in the mid-90s, about 30 years ago from the date of this message, it was possible to build CD players with extremely low distortion when measured with full-scale digital signal.

2. Across the time span of the survey, the very best performances are attainable only with a handful of DAC chips (or, nowadays, in-house DAC designs). So the specific make and model of DAC seems to matter. But it's also possible that manufacturers were incidentally only using high-end DACs in their best design efforts and that it would have been possible for them to achieve the same level of performance with lesser DACs, if only they had wanted it.

3. On the other hand, no one has ever succeeded in producing a source device with the best high-level linearity with some highly acclaimed DACs, such as the Burr Brown PCM1704.

4. Nevertheless, the specific DAC used in a particular device does not guarantee that said device will perform at the best possible level with that specific DAC. There are almost a thousand orders of magnitude between the most efficient device and the least efficient device that implements the high-end Burr Brown PCM1792 DAC!

5. The more time passes, the more we see devices being manufactured with modest or very mediocre performance, even when high-end DACs are implemented. I find this observation disturbing, because it seems to go against progress. Some manufacturers even seem to have made a specialty of deliberately designing devices with low linearity - Atoll, Ayre and (for most of its history) Wadia to name but a few.

6. At the very start of the introduction of SA-CD, some SA-CD players were able to achieve maximum performance, while no source capable of 24-bit replay (whether a DVD player or a BRD player or a separate processor or DAC) was capable of doing the same. It took almost ten years for some devices to catch up with the best SA-CD (and CD!) players, and these devices were neither cheap nor widely available. I find this 10 years gap intriguing.

@Scytales - I run a Daclist website (daclist.dnsbits.net) and I think it would be great to put all these tests into a similar database / website, if you are willing to share a spreadsheet containing the data.

Let me know your thoughts.
 
I updated the files this October 30th, 2023 with 4 new tests (see first post) :

Tests in 24 bits :
Rega Saturn MK3
TEAC VRDS-701

Tests in 16 bits :
Cayin MINI-CD MK2
MacIntosh MCD85 AC

After further scrutiny, I discovered that I have made a few errors : the Benchmark DAC 1, Lake People DAC C 460, Musical Fidelity X-DAC V3, RME ADI 2, Profitec TC 7500 et PS Audio DL III et one sample of Electrocompaniet ECD 1 were tested in HR PCM and not in 16 bits PCM.

The files have been corrected.

I have no objection, providing the source and my nickname are cited (I take responsibility for my mistakes in the files :)).

But, unfortunately, I only have text files and no spreadsheets for the time being.

Thank you - I will credit your work. I think that this would be a valuable resource to some people.

Plain text files are fine. I could even process the PDF files if I have to - but plain text would be easier!

I will send you a DM with my email address.
 
With permission from @Scytales I have created a searchable database with the THD info.

It's still in beta so they might be a few glitches but here it is.


@Curvature I have attached a .csv file (zipped) - however I note you probably already have this as Scytales has proved you with the files.

Thanks your for your interest in this data table and congratulations for your effort to put your site together :).

However, I see that harmonics and THD which are clearly distinguished by the metrics (dBV or dBr) in the original tables are mixed up on your site and the quoted THD in dBV is directly converted to percentage. To my mind, this is wrong.

For instance, the translation of the quoted -104 dBV THD of the Sony CDP-XA7ES on your site is 0,00063 %, as if the 100% level from which the percentage are calculated is 0 dBV, which is 1 V RMS. But the nominal maximum output level of the Sony CDP-XA7ES when 0 dBFS is played is not 1 V RMS. It is 2 V RMS (about 6 dBV). Actually it is well documented (Stereophile or Audio reviews) that the output level is a bit higher, about 2.5 V RMS (which is about 8 dBV). Thus, the actual THD is not 104 dB under 1 V RMS output level, but 112 dB under 2.5 V RMS, which corresponds to 0.00025 % THD relative to 8 dBV.

Problem is : I was not able to compute harmonics relative to full scale output neither calculate THD in percentage for every source for which the measurements have been showed in dBV by the magazines, because the analogue output level with 0 dBFS digital input of each and every source were scarcely documented.

In conclusion, I recommend that measurements in dBV remain clearly separated from the others and stated in dBV. Otherwise, readers would be mislead.

Also, the nature of the test signal become undocumented on your site.

Perhaps the "Note" column (in which I originally only put casual information about each device) could be replace by a "Test signal" column.

May I suggest a relabeling of the title of each column on your site :
