First, I’d like to say that this device is great and enjoying it, especially from line out more than headphones.
Volume control on line out would be great, and regarding headphones, I found it has a bit less power than my other headphones amp, but it’s good.
Now, I saw that there will be a new firmware that will support the SPDIF output, but I don’t understand why it should not allow to send a stream after MQA processing on this output, while it will od it one the analog RCA.
Once the MQA file is fully decoded(+rendering if any), the signal goes to the DAC to be converted from digital to analog, so it should also be able to send this signal without doing any conversion on the SPDIF output, with the exception of a MQA file with higher than 192kHz sample rate needing to be down sampled to 192kHz as it’s the maximum supported on the SPDIF output.
If that’s the case, isn’t it possible to limit the MQA processing to render up to 192kHz instead of completely not offering MQA audio (post-processing) on the SPDIF output ?
Offering this option would allow to use the Tone2 Pro as a MQA decoder+render (up to 192kHz) and send this digital signal to another DAC potentially being preferred by user, but not having MQA support.
