Well I know that all my settings were exactly the same in my situation from the MiniDSP to the Xilica. I don't know if they would be the same if my room or speakers was different, but it did work for me.Ron,
I don't know how similar the PEQ filter choices are between a MiniDSP and an Xilica. They are likely at least slightly different. My guess would be that any differences are trivial. If there were differences the Xilica would probable just shift the entered MiniDSP values into the nearest freq and Q values available in the Xilica.
The OP's question was for just using 2 different models of Xilica. The only difference there is they have a different number of inputs and outputs. In that case the filter setting choices are identical.
