Hi Vincent,
I appreciate your approach. Especially your search for characteristic like “no fatigue” or if one wants to keep listening. I would add “volume” – how low can it be.
Almost a decade we played around with PSUs on the first DAC HATs for the Pi
Now we seem to have time again and want to get into multibit DACs which brings us directly to the output stage. First passiv, later I would like to try what Lampizator page index is talking about.
On your 10K:60K output transformer do you use an I/V resistor on the secondary windings?
Any recommendation where to get those transformers from?
Thanks
