Thanks so much. Always get good info quickly here!

So... looking at used units, although you just said a v3 could be updated to v4 it seems there is a jump in money between those versions, is that correct? Prior, I was thinking the v3 was end of line and could not be updated beyond and that was the reason for the jump in desirability.

Is there a prior discussion re: changelog between versions, upgrade paths and what cards are interchangeable?

Last question, maybe this one deserves a new thread. I've run a 568 for a long time. My biggest complaint is that it doesn't give the option to send low end from the center channel to the L/R, it must go to the sub. i.e. I'd prefer a setup where I run my L/R full range, my center small sending everything below the cutoff to the L/R. Then send anything below a second cutoff from the L/R to the sub in addition to LFE. This because both I can hear the sub augmenting the center channel and the center channel sounds different than the L/R. Is this possible with the 861 and it's newer setup software?

Thanks so much.
