Hi,
don't want at all to be rude, and maybe I didn't explain it correctly, but to use your sentence, "you need to understand" that :
- I didn't ask for more than what the manufacturer declared as the SPDIF Output was announced and the device is built for as the SPDIF RCA is wired for that (the analog volume control was not in the discussion)
- I didn't ask for more, but gave a idea that could allow users, if the firmware can manage that, to switch between two options instead of switching between two firmwares, and if not possible, to not loose all the MQA processing on the SPDIF Output
More important, if your answer was the correct one, I think Eric (who designed the device) would have answer me like you did, instead of saying it's a good idea and they will discuss it to see if it's possible.
I meanwhile with almost all what you said in the following posts, with the addition of what Somebodyelse said.
You probably want too much from such a beautiful device, which is very tiny and with a very good sound.
By the way, I do not understand why this MQA is needed? In my opinion, this is another bad quality marketing. Sound quality is so-so, or not the best. But I listen old records)
