I would by a cheap DAC and connect through the cheap DAC.
IPad Pro to preamp
I listen 95% vinyl 5% CD but recently signed up with Amazon HD to stream music in my car. I like that you can make playlists and was wanting to know how can I connect my iPad to my preamp to stream without buying a Node or other streamer. And what would the sound quality be. My iPad doesn’t have a headphone Jack so the 3.5 to RCA cable is not an option.
