Ok, silly question, assuming the 4xSPDIF mod, how do you interface that to the 861? Current I am bringing 2 channel analog from my Sony 777ES into an IA45 card.

861v6, Oppo83 (3xSpdif Mod), Wiim Ultra running Squeezelite, Tivo Edge, Apple TV v4 with Key Digtial Audio Extractor, Von Schweikert fronts and center, Triad in ceiling sides and rears, Aerial SW12, Orchard Audio Starkrimson 3 channel and Sunfire Cinema Grand amps
