Power supply issues are present as Amir's graph, although a bit lower.
except for the power supply stuff, which he says were not present in his measurements.
You are clearly in a 50Hz country like me.
A-weighting will drop the power supply issues at 60Hz by about 27dB and at 120Hz by about 7dB or so. But we are going on the manufacturer's unweighted S/N spec of 120dB which we are nowhere near.
Comparing unweighted S/N numbers with the RME ADI2 is futile as the reference level is not the same @ 2 volts.
