... what is wrong with setting the Trinnov to 0dB? That is what you have to do not to loose resolution, what you have, when you not feed the 861 with a full signal (0dB)
Robert raised a good question. There is obviously some attenuation of the SPDIF into 8000, and that attenuation can be reduced by setting the 8000 at the lowest level. I have set it at 90 instead of 99 now. After a while I will try 80 and see if I can get the SPL I want at 0dB on the Trinnov.
Trinnov level goes above 0dB also! Need to see how far!
