Given the limitation of 96/24 on MHR, and the fact that I really can't see 768k signals moving around inside an 800-series box, my assumption is that the 818v3 will be moving signals at 96/24 internally, but in a new fractal "MQA" format. This opens up the possibility of up-sampling RBCD to 4x or higher sample rates, and handling 192k material (USB and SPDIF inputs) without down-sampling it.
