This system was built for simplicity, just 2 boxes and a power conditioner and a pair of Kelinac 714 MG speakers.   The Mimas integrated amp( with DAC card) is plugged directly into the wall with stock power cord.  I have the Hijiri Nogamo power cord for the Aurender and the Silversmith Fedelium speaker cables and I have a Tchernov USB pro.  For tweaks I have a Synergistic Research Purple Fuse in the Mimas, and the Synergistic Research black box in the corner, although I'm not sure that black box does anything. LOL.
