[Streaming player (Sony Walkman) vs. iPhone 6 for Tidal]

I just started using Tidal.  Is it worth getting Bluetooth streamer like the Walkman versus using the iPhone six?

 

Also, is the Walkman the only budget portable device that can stream Tidal?

 

Thank you very much.

[How can I connect my Aune X1S to my iPhone 6 digitally]

Hello,

I'm new to audiophile headphones and I mean completely. I bought based upon recommendations on various websites an Aune X1S.  I play Spotify with my iPhone 6 and sometimes my Mac.  I understand that I can use an RCA cord to do analog.  I want to know how I can connect it digitally?  I read that I need an Apple lightning camera connector.    Is this the one? 

Here is the back of the Aune X1S: 

Thanks for any help that you can give
