I was told by Meridian that the SE speakers display what they are receiving before they process/render.
Hi Ken
That has been the case since I first started using Meridian kit more than 20 years ago... it always displayed the incoming stream.
However, 2 things make me wonder:
1) In my Tidal to Explorer scenario above [with MQA Pass thru OFF]... the Explorer displays One Blue light and up to TWO white lights... even though we know it's only receiving a 24/96 PCM stream... which should mean that the Explorer should only display two white lights.
2) And in the case DSP SE displaying 352k MQA from the 2L content, then I recall Meridian's YEARS long argument that anything above 24/96 content would require new cabling and connections, i.e for 24/192... so one can only imagine what one would require for 24/352 PCM content.
Of course, Meridian could be fully decoding to 24/352 PCM within the 818... but then compressing that using MLP... and sending that 24/352 data via MLP over MHR to the DSP SE's.
But IMHO, it may well be simpler... and more in line with how other manufacturers appear to be dealing with MQA... that the 818 does the 1st stage up to 24/96... with the DSP SE's handling the 2nd and 3rd stages.
All IMHO
