Reactor now available in stereo!

[Juanbk]

Hello everyone, i have couple questions.
Im ready to buy my second Reactor, i work onboard a ship so I cannot use it with the ship’s
Wifi. I was thinking if it’s possible to buy a router and set them up that way, but im not shure if the app will work without internet connection.
I saw here that some of you talk about connecting them on the same power strip, or toslink etc..
But to be honest I’m new to all this and got confused.
Can anyone of you tell me all the ways i can connect them to get stereo and more importantly 
Which would be the best way for best sound quality?
Best!
Juan
