No, not at all. I don't think it is worth it for us at this point. I am
ordering 6 channels of one to one isolation to give isolation for up to 4
monitors and two mains (all mixer outputs to stage). I will put digital
lines (wiring, but no switches or other end points) in during reno so that
in the future we can change things if we like. There are other things
network can be used for besides audio as well. But our audio will stay
analog probably at least as long as this new mixer we just installed
last year.

It is already amazing what new options are available since I picked up the
mixer. I am hoping it will be good for another ten, but even five years
from now, digital could be cheaper than analog... CAT5 could no longer
used for that matter.
