Signal path is “Enhanced” if I play MQA. Why not “Lossless”
Simply because MQA is NOT lossless and will never be.
This is correct according to Roon designation.
Assuming the signal path is accurate, you’re actually using the wrong configuration. You’re defeating the MQA rendering by the Rotel.
Hello Peter, I know, but it is still sounding much better 
Thank you anyway, nice day, Lambert
Addition:
So the “MQA full decoder” ( step 5 on the signal path ) is “enhanced” and not “lossless”, is this correct?
Thank you
The endpoint is reporting back to Roon that it is performing MQA decoding, which Roon considers as signal enhancing by Roon.
It’s just semantics I’d not read too much into it, but for me that description feels about right.
What’s important is that Roon’s signal path is transparent and show the step in the signals path from Roon to DAC (cavate provided the DAC reports the correct information).
MQA Full Decoder and MQA Rendering are Enhanced.
You are now using the wrong settings. But hey, if it sounds better to you, that’s all that matters.
Settings should be:
Roon core decoder off (unless you use Roon DSP)
Rotel set to decoder and renderer.
Signal will be enhanced and that’s how it should be 
Raz you can’t stand between a man and better SQ even if he is holding it wrong 
Absolutely not
That old Steve Jobs quote always comes in useful 
For endpoints that support MQA decoding, provided the later is set correctly there should be no need to switch off the decoder, as Roon will not activate it unless DSP is used. Switching off the MQA Core Decoder in Roon creates a potential trip hazard should any DSP features be switched on in the future.
I personally would not advise users to switch off Roon’s Core MQA decoder, but do concede it can give “piece of mind” to some users.
