MUSINGS: On the RMAF 2018 MQA talk, pseudonyms, and the right to anonymity.


“A desire for privacy does not imply shameful secrets; Moglen argues, again and again, that without anonymity in discourse, free speech is impossible, and hence also democracy. The right to speak the truth to power does not shield the speaker from the consequences of doing so; only comparable power or anonymity can do that.”
--- Nick Harkaway, The Blind Giant
Boo!

Well, Halloween's coming up and it looks like we're about to talk about some scary, dramatic stuff involving emotional incontinence and anonymity :-).

MEASUREMENTS: RME ADI-2 Pro FS as DAC (Part II - frequency response, noise, distortion and jitter)


As we saw previously, the RME ADI-2 Pro FS is based on the AKM AK4490 DAC chip and provides a good assortment of features like filter settings. We've seen that the headphone output amplifier provides plenty of power and the beginnings of what looks like a highly accurate DAC; consistent with my subjective opinion.

Time for part 2 of the objective evaluation today as we continue to explore the DAC output quality.
