My preference would be for them to eventually consolidate their marketing teams too, and eventually settle into something like the following strategy:
a) Continue to go with both brands, so people have choices on the style and physical features.
b) Re-introduce Denon AVP, could go with a lower priced model based on the AVR-X6800H.
That way, people can pick their pick based on their personal preference based on styles, physical features only, without having to worry about which "sound signature" they may or may not prefer, and to be brutally truthful, avoid using misleading marketing hype, or some may feel those borderline on perpetuating myths even "lies".
It will (imo) be a win win, as D+M/Masimo could lower their cost too, when they don't have to keep putting in the useless HDAMs, while implementing the two filter options for both D and M lines. Further consolidations naturally also mean more potential for cost reduction.
