Bricasti M3 In the house

Just got a Bricasti M3 with the Ethernet renderer module. Looking forward to breaking this piece in. First impressions are: it’s a winner. I am curious what ways folks who have this DAC (or other Bricasti models) run it; over ethernet or USB? I will report my findings as the days tick by; Right now it’s cooking on ethernet out of my InnuOs Zenith MKIII into an ether-regen into the M3;
Thanks!
