Ayre QX-5 - maximize use and wiring question.

I am currently doing an in house demo of Aurender N10 and Ayre QX-5 twenty. I'm really pleased with the music produced, as is the wife and family.

I use the RCA out on the Ayre to a Marantz AV7704. I'm using the 7.1 input on the Marantz to avoid it's DAC and just pass through the music to my Sigma 2Amps onward to B&W 803D3s.

My question is, what other uses are there for the QX-5?

I have no Vinyl or CDs - having converted to completely digital years ago. My Apple TV 4K only has HDMI so can't really see a way to get the DAC in the Ayre to decode music from the Apple TV - Hence the Aurender.

Fios TV, it does have optical out, I could use the Ayre to decode the music channels? But for TV movies it would be useless since it can't decode surround sound?

Steaming services work through the Aurender and Ayre.

I'm thrilled with the music produced with the Aurender and Ayre combo. I'm just seeing if there are uses that I'm missing.

Thanks.
