Best Way to Connect Audio Server to AVP2?


I am setting up a Mac audio server. I would like to pipe it through my system via my Proceed AVP2. The AVP has 1) AES/EBU, 1) Optical, 1) S/PDIF BNC & 4) S/DIF RCA digital inputs. The DVD transport uses the AES/EBU & the xbox 360 ties up the Toslink. What should I do with the Mac for jitter free, reference quality audio w/this scenario?
