I have a multilane house with 8 Essene MK II (and 5 all in one speakers A9, M5, etc...)
Two Avant NG with Essence as well.
I have never been able to get the system really stable. Constant problems.
3 times out of 5 Music "Can't be added to this playlist". Reboot sometimes helps, sometimes doesn't.
BeoTool shows a 'phantom zone' (2 zones named Living Room, 1 is live, the other is an old setup) that is impossible to delete.
Also the only way to play music on the TV's is by first starting music in a normal Essence Zone then linking them.
I am tempted to sell all the Essence MKII and replace with new Core and start totally fresh (new B&O account etc..)
Does Anyone
A) Know if the Core is actually any better / more stable / faster?
B) If not, know what the best way to start fresh is? The phantom zone was created when I tried doing a factory reset - this eneded up bricking the unit and it took B&O almost 3 months to return it to me.
C) Any other advice. I know its a fairly big set up but there have been moments (ie a full week) where it has more or less worked.
PS Most connections are wired, a few are wireless. The network/wireless set up is enterprise grade (Meraki) so I doubt it is anything to do with that.
