Best to talk about specific devices: - Sooloos doesn't use MHR so it will output unencrypted 24/96 if you allow it to upsample.
Good. I am hoping this means that the 861 output from the Sooloos' input to it will remain unencrypted.

- The 808.3 and 818 are a bit more unclear, and someone who has actually done it will have to jump in. The manuals say they can apply "optional MHR" to high-speed output. But at the same time input which is already encoded in MHR (i.e. from an HD621 run in stereo - covering your BD/DVD question) will have to stay in MHR if it is going to stay high-speed.
That's what I feared. I use the HD621 for my HD MCH sources and the necessity for having MHR (or is it MHHR?) on would mean that the 861's SL output from them would be downsampled. I would have to resort to a modified player with 3xSPDIF to maintain HD unencrypted through such a setup.

Is that the sort of thing you mean?
Yes. Although not completely definitive, it gives me useful input.
