Streaming virgin


I know this is a broad topic but I have to start somewhere. Up to now my source has only been my cd collection. I would like to get into streaming to discover new music.  My current system is modest consisting of a Simaudio 340ix integrated and 260d transport.  Speakers are Focal936.  I currently have a Spotify premium account that I use with my Amazon kindle tablet and ear phones.  I do not have a PC at present. So, where do I start?  Will I need additional equipment ie computer, server, etc?  I am pretty ignorant with all this tech stuff.  I'm looking to get quality sound as easily as possible and if I have to spend a few bucks to do so thats ok.

The blusound node is a great start, but if $500 is too much for starters l would suggest the Dayton audio WBA31. It is around $50 at Parts Express. It has RCA and optical outputs. It supports Tidal, Spotify (paid subscription) and many others (not Qobuz) by wifi streaming.
@dagery
although not required, you might want to add Roon - a software which makes all you file sources look like one library, and allows you to do in depth queries like “which albums did this drummer play in”

I second the Node.  They just upgraded the DAC and you can compare it with the DAC in your amp.  I like the Bluetooth option for discovery but the Node has both Bluetooth and AirPlay, so even if Spotify and Bluesound don’t work with each other you can still stream to it for discovery
For $549 USD, the Bluesound Node packs a lot of features.  My connection preference:  ethernet cable to the Node, then USB or SPDIF to your amp.  It can be controlled from an IR remote, a desktop application, phone app, or its own box-top buttons.  Plus, it's a Roon-ready device.

I'm not extremely tech savvy either so I went an easy way and purchased a Marantz ND 8006 CDP/streamer and its so easy to use. I also have Spotify and the 8006 connects to your phone via Wifi---then voila! Spotify is streaming through your stereo. Good DAC too! Its a great piece for streaming and playing CDs.Technics also has a new CD/Streamer that's getting good reviews. Good luck!!
