Hi @amir, following a discussion in one thread in which a member described blind AB testing done with a range of DACs feeding a passive attenuator and a very low impedance power amp, it occurred to me that perhaps measurement of electronic components’ output and (if applicable) input impedance wouldn’t be a bad idea.
I googled the DACs that member had tested and was able to find published specs on only two thirds of them, and there the range was 1 to 500 Ohm output impedance, with no data re impedance vs frequency.
This is one metric where reliable data may actually be quite helpful to some, and also a metric that is not commonly even spec’d let alone measured.
In most cases I’m sure the results will be unremarkable, but it appears not in all cases..
