I am using an Apple Airport Express to stream my music from Pine Player to my NAD C388 using an monster optical cable with an Audioquest adapter tip for 3.5 mm audio plug. It streams from Airplay from my 2018 Mac Mini. I have Klipsch RP-280s speakers. The Pine Player has an oversampling filter that works very well with this set-up. Pine Player is available in Apple's App Store free. I would like to see a review from the professionals at Audioholics on what they think. I can't find any reviews online.
