What do I need to start Streaming Music thru my Audio System


Im an Old Man that needs help! I would like to try Streaming Music thru my stereo but have no idea how to do it. I have a Lap Top Computer. My system is as follows: Emotiva XSP 1 Pre Amp, Genesis Digital Lens, Wadia 321 DAC, Audiolab 6000 Transport, Bel Canto REF 1000 Amps, Thiel CS 6 speakers.  Any help would be greatly appreciated!!!

How much you looking to spend, do you have an ethernet port close or is this going to be wifi? You could hook your laptop to your Wadia DAC by USB and try some free internet radio stations to get an idea but it will be low resolution files. If you decide to buy into a subscription service like Quboz or Tidal it's  easier to use a dedicated streamer like the Node2i mentioned above but a tablet or smartphone is the preferred way to control though a laptop can be used.
