Subjective rating the same. The better noise floor does reveal a bit more - not sure it did any favors. (Note, corrected last graph, the 19.1kHz test which was missing).

Love the measurements. My new mantra for audio: "Measurements or it didn't happen."

This is one of the units with selectable digital filters, yes? No?

Yes, all measurements were done on standard filter.

Wow, that much roll-off from the standard filter? That's special! Haha.

Found this as well for comparison: http://ifi-audio.com/audio_blog/does-the-nano-idsd-measure-good-bad-or-ugly/

And the stop band attenuation is insufficient.
I'm no expert on this, but on the Soekris Dac this kind of stop-band is audibly shitty sounding. At least -110dB is needed, to my ears.
But then NOS (not true, pure nos though) was fine on it..

Stop-band attenuation and slope ... based on personal preferences. The AGD M7 allows the user to change this. The higher stopband setting on the M7 had a denser sound, but grainier treble.

So this ifi's Thorsten Loesch isn't as “Tonmeister” (“Soundmaster”) as he claims to be... basing on how bad the Ifi measurements are.

It's an inexpensive implementation running off of USB / battery power. I wouldn't expect it to have exemplary measurements. Subjectively the sound is nice, warm, and rolled and quite unoffensive (no digital glare, digitius, nasty treble, etc.). Maybe too inoffensive and forgiving for my tastes. Attacks and dynamics are soft. Microdynamic and microdetail is poor. What would be interesting is to compare measurements from DACs that sound differently.

I added one more measurement to first page, 600Hz and 1700Hz two sine plotted on x-axis log.
