you could plug a DAC into your tablet - use the Toslink port to get galvanic isolation
Lossless iTune music
Do you listen mobile device music from your system? I use ipad instead of CD player now. I rip music from CD to lossless file in computer then import to iTune and Bluetooth stream music from iPad to my system. I tried Tidal, but didn’t like to pay $19 a month subscription fee. If you store hifi music on mobile device, where do you get it from? Thanks
