For the purists where should digital start.

For some like Phil Ramone who does the Gramys TV brodcast. It starts at the mic splitter and ends at you TV set. For others it starts after the Neve analogue mixer and ends at your TV set.
It's a mad world out there.Theres nothing like the sound of a NEVE and if you can reproduce it's musicality . I'll go for after the analogue mixer.
