Where is the officially puplished source from Meridian with the "not full MQA" for the 861 ? Was/is there an official update question for that issue ?
I will not believe/hope, that this is maybe for the "moment" for MCh,
but simply adding cards makes a new machine would be an intermediate solution**

There are NO secrets about the "motherbord" what is NOT a motherboard
as like PC have.
Its simply a "distribution board", there are NO active device on that bord beside some small capacitors.
So there is no brake just to install the same card as the 818v3 have and have for the start two channels.

The future of the 861 or better say MCh-music strategy/support/availability from the industry would be the major factor for the decision what to do.

** I think M have another concept/solution in their mind for the future as that be "logic" but speculating here in public doesnt support M from their competitors..
But hopefully we will see and maybe hear soon?
