Not in any sort of 'traditional' "tube rolling" sorta way, as in 'plug and pray'.
The case needs to be opened up and 2 big boards swapped out along with a f/w chip.
This is not a big deal for anyone who has 'electronic technical chops', but I'm sure as
(is) Schiit, that all onus is upon the 'installer' in terms of warranty/doa issues etc.
Here is an extreme example for sure, but Many years ago a single board was pulled from an electronic device while it was still plugged in.
It blew EVERY chip in the entire unit (as in several hundred CMOS TTL chips) did I mention this was Many years ago?
And all it takes is to blow just one IC…
Just say'n is all…
