It is a 2s time shifted digital copy of the original. You likely did something wrong. You must record the analog output through the analog input.

Now who could argue with that? I'm particularly glad the young people were able to see that rant. Not only was it genuine old school audiophile gibberish, but it showed a command of the Queen's English rarely seen in this day in age.

Hmmm... I will try again this weekend. Sorry for the mistake didier, I will enlist help on the Axe-FX forums to get this right!

Anyone could provide files and data for Crookwood converters?

So in summary the Forssell MADC-4 clocked to the Focusrite Blue 245 gave the most transparent result? And the Lynx Hilo gave the most transparent result of all converters using only internal clock?

Yes. But IMO the most important is which DA converter and, may be still more important, which AD converter rather than which clock.

How would you explain the Motu, Lynx Aurora, And Rme units outperforming the Apogee Symphony, Prism, and Forssell units in these tests? Do you think these tests have user errors, the test itself is flawed, or have all the opinions regarding the superior quality of the "higher end" units like Apogee, Prism, and Forsell been wrong all along?

Most of the results are in agreement with the expectation of the users of these units. Good result from Lynx Aurora, and still better ones from Lynx Hilo, are not a surprise. Apogee Symphony, Prism and Forsell results are much above the mean as expected. Yes there are a few surprises. We all know that there are some myths in audio. Anybody can do the test and can perform the measurement. The wav files are available for listening. It is a transparent test about DA-AD conversion transparency.

It's too bad alot of these links are no longer active. Was looking for Pure2 sample.

I will update the link for Pure2 by Saturday.

Edit: Done for one of both files.
Updated list of results

Test of the Audient iD 14 by sm5:
ADM: -2,819msec, 8,821dB (L), 9,063dB (R)..Corr Depth: 22,2 dB (L), 23,7 dB (R)
Wavelab measurement of ADM difference file: Difference: -41.9 dBFS (L), -42.9 dBFS (R)
Matlab: -2.82361 ms, 8.8197 dB (L), 9.0620 dB (R), Difference: -42.6 dBFS (L), -43.9 dBFS (R)


DA-AD loops from this wav file evaluated by means of Audio DiffMaker.

'Difference' indicates RMS level figures measured in Wavelab from the difference file delivered by Audio DiffMaker.
'Difference*' indicates RMS level figures got from a difference file generated in Matlab after refining the time offset and gain figures provided by Audio DiffMaker in order to get the lowest difference level. Hence the 'Difference*' figures are lower than the 'Difference' figures.

Read also this about the test method.
See at the end of this post how to contribute to the test.

Unsynchronized mode. The DA and AD converters run each on its own clock. Measurement performed with sample rate drift correction activated in Audio DiffMaker and limited to the first half of the sample. Because the RMS level of this first half is 1 dB lower than the RMS level of the full-size sample, one must increase the difference RMS level figures by 1 dB for comparison with the synchronized mode.

Audient iD 14 ---> Lynx Hilo master test from sm5:
ADM: -5,311msec, 5,796dB (L), 5,772dB (R)..Corr Depth: 25,4 dB (L), 27,1 dB (R) Difference: -44.5 dBFS (L), -45.4 dBFS (R)
Matlab: -5.30871 ms, 5.8001 dB (L), 5.7712 dB (R) Difference: -45.3 dBFS (L), -46.2 dBFS (R)

IS there anyone that has a Burl B2 Bomber to compare?

There is this one in the above list of results:

Metric Halo LIO-8 ---> Burl B2 Bomber ADC (Antoine Fabi)
LIO-8 or B2 WC master, -14 dB / -16 dB B2 input: 1,8 dB / 3,8 dB (L), 1,8 / 3,8 dB (R)..Corr Depth: 35,3 dB (L), 36,8 dB (R), Difference: -54.8 dBFS (L), -55,7 dBFS (R), Difference* (B2 WC master): -55.7 dBFS (L), -57.0 dBFS (R)
B2 AES master, -14 dB / -16 dB B2 input: 1,8 dB / 3,8 dB (L), 1,8 / 3,8 dB (R)..Corr Depth: 35,3 dB (L), 36,8 dB (R) Difference: -54.8 dBFS (L), -55,6 dBFS (R)

However any other test of the Burl is welcome.

Unfortunately that link is dead. Plus if I understand it would be going throug 2 converters correct? I would really be intrested in the loop just going through the B2

I have updated the LIO-8 --> Burl B2 link. By definition DA-AD loop requires a DA converter and an AD converter.

Ross Martin AES EIGHT 1794A DAC into Metric Halo ULN8. The RM Audio DAC clocks off the AES signal from the ULN8. The ULN8 is running off internal clock.

Thanks!

Here's the measurement results

from ADM: -330,8usec, -0,139dB (L), -0,334dB (R)..Corr Depth: 36,3 dB (L), 37,9 dB (R)
from ADM's difference file measured in Wavelab: Difference: -56.1 dBFS (L), -57.2 dBFS (R)
from Matlab: -331.71 µs, -0.1395 dB (L), -0.3344 dB (R), Difference: -56.8 dBFS (L), -58.2 dBFS (R)

To be added to the list of results later on.

Fascinating.

This would suggest that the Ross Martin DAC is at least as accurate as the Metric Halo box is. That confirms what I hear in that I have three DACs in my studio, and two of them, the Ross Martin and the Metric Halo sound almost exactly the same to me. I have a third which is a HLLY stereo DAC which does have a different sound.

It would also suggest that potentially the weak side of the Metric Halo box is the A/D which seems to confirm the oft repeated premise that A/D is harder than D/A.

Thanks for running those numbers so quickly!!

ADM: 6,709usec, 0,092dB (L), 0,090dB (R)..Corr Depth: 35,1 dB (L), 36,3 dB (R)
Wavelab measurement of ADM difference file: Difference: -55.5 dBFS (L), -54.1 dBFS (R)
Matlab: 6.04 µs 0.0835 dB (L), 0.0494 dB (R) Difference: -55.7 dBFS (L), -55.7 dBFS (R)


DA-AD loops from this wav file evaluated by means of Audio DiffMaker.

'Difference' indicates RMS level figures measured in Wavelab from the difference file delivered by Audio DiffMaker.
'Difference*' indicates RMS level figures got from a difference file generated in Matlab after refining the time offset and gain figures provided by Audio DiffMaker in order to get the lowest difference level. Hence the 'Difference*' figures are lower than the 'Difference' figures.

Read also this about the test method.
See at the end of this post how to contribute to the test.

Unsynchronized mode. The DA and AD converters run each on its own clock. Measurement performed with sample rate drift correction activated in Audio DiffMaker and limited to the first half of the sample. Because the RMS level of this first half is 1 dB lower than the RMS level of the full-size sample, one must increase the difference RMS level figures by 1 dB for comparison with the synchronized mode.

Thank you !

Would love to see Apollo 16 mk2

Someone with the Focusrite Rednet converters needs to get in here and contribute.

hello didier and friends!

I have a question.

I'm interested in buying a new pci express card. I already have an esi julia pci-e and one pci. now when looking at these test results i see its right up there with the expensive lynx equivalent. and way ahead of the RMe eqivalent.

I had my eye on either the rme or the lynx. but now it seems my esi is just as good as the lynx??

Or is it??

I mean what does this test really tell? I'm not trying to be critical I just want to know if this test somehow relates to either recording quality (1 round) or playback quality (1 round)?

I mean both the lynx and rme pci cards perform better (like 5-10db better all over in rmaa tests) with all other tests than the esi. But in this test the esi is on par with the lynx.

So I basically want to know if there will be a real improvement if only listening to pre-recorded material or recording things via line in when going from the julia to either the lynx or rme in real life?

Can you advice?

the julia pcie is like 1/3 price of the rme...

You could surely easily keep your Juli@ card and just make music with it.
It all depends on the quality you want to reach, and more important, how many inputs and outputs you want to use at the same time.

It tells how a digital copy through DA playback and AD record is close a digital original. It gives measurement figures but you could also listen to the ESI, Lynx and RME copies (download links are available. If one link is no longer valid, please tell me and I will update it.) and decide by yourself from what you hear.
Usual S/N and harmonic distortion figures are much lower than the level of the difference between the copy and the original measured in this test because they relate to marginal effects with respect to how a signal is modified through DA and AD conversion.

So didier. what will sound best when playing a wav file?

Lynx/rme/esi? or no difference whatsoever?

Do you hear one sounding better than both one other ones from the DA-AD loopback copies of the original in this test after having compensated level discrepancies ?

ESI Juli@ XTe (apply -0.3 dB gain for getting the level of the original))
Lynx L22 (apply 2.9 dB gain for getting the level of the original)
RME HDSP 9632 (aplpy 0.5 dB gain for getting the level of the original)

Not sure if I did the test correctly. I guess we'll know by how the L22 compares to what others got.

Thank you for your contribution. I cannot get access to mediafire by now. I should be able to download your files by the end of this week.

I have got both files. Here are the measurement results:
