Just added a page to DeltaWave website with data reprocessed from the Gearslutz AD/DA loopback test page.
It's a subset of all the files. Since this was done automatically, by a script, there may be some things that are mislabeled. Let me know and I'll fix them:
Ordered by increasing value of PK error metric, here are a few top contenders:

Hi pkane, I will intsall your lastest release, thanks for the work on this software ;-)
I saw that you can edit some information in the results page for the loopback test :
the Echo AudioFire 8 almost at the top was synced via ADAT, which means it has ADAT ports, so it's the 2nd version.
It's called AudioFire 8a, and has AK4620B ADC/DAC chips
The 1st version (8 without "a") has no ADAT port and CS4272 chips.
The AudioFire 12 is in the same case (AK4620B or CS4272), but we don't know which one it was (only the Firewire ports pointing differently).
Last, the AudioFire 4, don't know too, but both versions have less differences (AK4620B for 2nd versionn, 1st version has AK4620A)
I saw an error for the MOTU 828 MK2 : I used the file I recorded with my 828 MK2 USB, and got far higher numbers than the one here :
-56.7 GSRMS, -56.7 DWRMS, -90.3 DW RMSEQ (dBFS), -100.3 DW RMSEQ (dBA) and -107.9 DW PK Metric (dBFS)
Can you check the file you have for this device ?
I will also run it from the 828MK2 Firewire
I also saw that there's an RME Babyface Pro test on GS with headphones outputs that gives better results than the XLR outputs, maybe it can improve the other DW results
