Had my 861 upgraded this week. Still getting my head around sound differences, recognizing the need to let the unit burn-in and that I will probably need to rerun room correction (as opposed to just copying in the v6 settings), but everything works fine. low bass seems better, but mid-bass worse - again, probably just need to rerun RC. No problems with ID41.

Biggest pain was probably rebulding the v8 Mconfig profile. I just don't go in there frequently enough for there not to be a new learning curve each time. But it's done.

One thing I did find was that the weight balance in the unit has shifted due to the additional weight of the LPS - took me by surprise when lifting the unit and expecting the same rear-inclined weight balance. I almost dropped the damn thing.
