External DAC connection

Greetings Audiogon members, 

I am an audio enthusiast and have been struggling to wrap my head around this question. First a little about my audio set up. Simaudio W5 power amp, Marantz AV7701 preamp, OPPO105, Apple TV gen4 (HDMI), benchmark DAC1, Von Schweikert VR4 speakers.  

What is the best way to connect my Apple TV (to listen to Apple music and Pandora)? If I use the OPPO as a transport, by connecting HDMI from Apple TV > HDMI IN of OPPO > Coax digital out of OPPO > benchmark digital Coax in > benchmark R/L out > Marantz Analog audio in. Will this set up work and if so, will I not be double dipping into the benchmark DAC and the Marantz DAC ultimately listening out of the Marantz DAC? 

Or should I be using an HDMI De-Embedder? HDMI from Apple TV > Kanex de-embedder > HDMI IN to OPPO & Coax digital to benchmark > benchmark R/L out > Marantz Analog audio in. Will I not run into the same issue of ultimately running the sound of Marantz DAC instead of needed benchmark DAC? 

Is there another better way? I would like to use my pre-amp and don't believe it has a HT-bypass

Help please? ghulam
