Thanks for testing.
I tried to compare the old against the new version, but what i miss here is the Power vs Distoriton graphs of the headphone out. Side by side would be awesome. We have a slightly better DAC. I And If i just compare the SINADS of the headphone output. I don’t know what he measured, I think it was high gain with 300R, we even have a better result for the new version.
So the output impedance is way higher, does ist really matter that much. My personal answer based on the diyaudioheaven graphs, with 120 ohm added impedance, of my headphones, no. So maybe i miss the point, but it seems to be a better device.
What i miss is a 6,3mm output but you can't have everything.
