K41 is a nice solution. It offers an extremely clean ethernet input. I have tried it as an alternative to the Nucleus + as that is my other server. This will be an improvement as the processor is quieter and the direct connect from Antipodes to X1 should provide a cleaner connection than just about anything else.
I have a customer who is running one (K40) with a Weiss and it is extremely effective.
Incidentally, I am an Antipodes dealer and a Roon dealer.
