I corrected in the "Review" hereThat's hardly doing anything. I mean, ~24 dB filter ultimate? My guess is it's still overloaded.
I'm in Europe, so 50Hz.Hmm. I can't help but notice that 60 Hz x 2 = 40 Hz x 3 = 120 Hz, which could be a power supply related thing. That said, your spectra previously were clear of mains stuff, so....
I limited number of harmonics in THD computing and result looks much better.
See the "review" as well.There's still some funny business going on though, note the glitches whenever it ought to be hitting the first Gibbs peak after transition. The same at +13 dBu might be interesting to tell whether it's the filter / DAC or the analog side.
That's coming.It would certainly be interesting how the mic inputs are doing. (EIN at 75/60/40/20 dB shorted or 150R, THD(f) or IMD(f) at -1 dBFS for at least a few of them.)
