Thanks - I think the specs were only uploaded yesterday.
And yes, it seems that the CI is 'capable' of processing 192kHz audio and passing that on through the AES/EBU output
(AES3 standard - which mentions 192kHz under 'extended sample rate') - which I assume can actually be passed to a Meridian 271 via the DB25 connectors after all.
AES67 is just a standard - or 'container' and can pass almost anything, but I've read that the Dante protocol is often limited to 48kHz - as you mention - which means that the 'ethernet' / RJ45 connection route would not be the best one to choose.
My 'concern' was for Stereo & other Audio listening formats, that the CI might be limited to 48kHz, but that seems not to be the case.
This is good news & puts my mind at rest that my purely Audio listening won't be compromised if I swap out my 861v8 & keep my Meridian DSP set-up, although of course Trifield will no longer be available.
Time to start saving!
