MQA External DAC
Answered
I recently purchased a Topping E50 DAC. When attempting to export MQA files to the DAC with controls set as shown in the manual (External MQA DAC enabled, fixed volume, tone controls disabled, etc.) The DAC will only receive PCM. I tested the DAC with the WiiM mini and it received MQA without issue. I have submitted four requests to Bluesound and each one comes back “Solved” no matter how detailed my explanation is of the issue and can’t get someone to contact me. During the course of trying to solve this issue, I have rebooted the Node 2i several times, did a hard restart and logged out of tidal and logged back in. Nothing resolved the situation. However, when I disable the external DAC function, the external DAC and Bluesound app shows MQA. What gives?

I don’t think there is anything to resolve but stand corrected…
The D50 is an MQA render on the optical and coaxial inputs, with external DAC turned off your Node completes the first unfold (core decode) and then send this signal to the DAC which acknowledges it as an MQA track then further unfolds the signal hence indicates correctly it’s an MQA track and gives you the best sound from it.
Edit
With external MQA DAC turned on Bluesound will send the original unaltered file to the DAC but this requires the DAC to be a full Decoder.
For info… The USB port on the D50 (according to the docs) is a full MQA decoder. The Bluesound Node is a full decoder for the analogue out ports. -
Thanks, for the info. Hope you can understand my confusion. Just wanted to make sure I am using it to its full capability.
