I'm looking at moving my 2ch listening system to this item: https://www.amazon.com/gp/aw/d/B00F0Q8D4E/ref=psdcmw_537344_t1_B07992VZ6L My guess is this will replace my old AVR and I will need optical outputs on all my devices, as this has no analog . I mainly play offline downloaded 24 bit files from spotify through my android as the source. I use aux to RCA but that goes to wifi with this model. Anyone have thoughts about this pure digital move? I'm still educating myself here, any opinions welcomed.
