Zoom F4 tested by sm5 (main out in XLR 1/2 ---> preamps in the loop):

ADM: -21,43msec, 0,107dB (L), 0,054dB (R)..Corr Depth: 16,2 dB (L), 17,7 dB (R) Difference: -35.9 dBFS (L), -36.9 dBFS (R)
Matlab: -21.44108 ms 0.0654 dB (L), 0.0216 dB (R) Difference: -36.6 dBFS (L), -38.0 dBFS (R).

To be added to the next issue of the list of results.

Here for the gear
 

Great data here!

Some data for the RME ADI-2 Pro FS (XLR loopback):
Amazon Drive

Summary:
-1.998 sec, 0.249dB (L), 0.244dB (R). Corr Depth: 33.6dB (L), 35.1dB (R)

Essentially the same as the regular ADI-2 Pro (non-FS).

Yes : see here the result from the first test performed by LesC.
But it appeared further that much better result can be achieved by modifying the setting of the I/O filters. I guess that default settings of input and output filters are both SD Slow or SD Sharp. SD means small delay: latency is minimized but distortion is larger. Could you make the test again with 'Sharp' setting (without SD) for both filters ?

The old MkII was designed circa 2002-3, before all the electronics companies rushed to China in a race-to-the-bottom price war. Hence, build quality and components were at a higher standard than gear built today.

Still can't beat MOTU's mac drivers though... Solid and consistently updated - software drivers are the heart-and-soul of any converter!

List of results updated with tests of Zoom F4, RME ADI-2 Pro FS, Sound Devices MixPre-10T, Audient iD44 and MOTU 828es.

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.
