Just go wireless.  Bluetooth or airplay is the way to go.  No need to pay a lot if you want to use your iPhone, just go on amazon and find the cheapest solution you can.
Bluetooth is sonically challenged. The best simple way forward is either an Apple Airport Express or a Chromecast Audio, but both need wifi to connect so will not work on the go. Both have optical digital outputs for unimpaired sound quality. The advantage of the Chromecast is that the actual streaming is not from your phone/tablet, but from the Chromecast itself. Therefore, the phone’s battery is not drained - you can even turn off your phone. For both units there are apps for a great many streaming services - you are not limited to a handful as with many dedicated audio brand streamers.
You could try an Audiengine B1 Bluetooth muscic streamer. They have a 30day return policy if you don't like it. I have one and I stream internet radio from my Samsung Tablet and it works and sounds very good. Pretty surprising actually.
