Streaming virgin

Correct. All you need is a streamer digitally connected to the amp. As suggested a Bluesound Node is what many people start with and an end for some. If you want to get something that is comparable in quality with your current gear you might look at the Lumin or Bryston products.
As far as connectivity, generally, the streamer will need to be either Wifi Capable our connected via ethernet cable to your router/modem. Most people will tell you its better to have the streamer hard wired to the network especially if your wifi is shaky. I use a mesh network and have a mesh node sitting near my rig and then hard wire ethernet to the streamer. Purdy solid.

Deezer,Tidal and Qobuz are your services along with The Amazons for higher resolution.

Note. As I mentioned before you could get started with a nominal investment in a tablet that has digital out capability.

Bluesound has a nice user interface- I think worth the cost. 

This is what I use, it sounds good and it's been pretty bulletproof 5 years and still going strong. Auralic stopped making them and they are almost never on the used market this one won't last too long. You will need an IOS device Ipad or Iphone to control it.

Your Phone.

So, where do I start?

I have to start somewhere.

A broadly optimized streaming device no one ever thinks of, nor mentions.

I’d stay clear of the headphone outs and Bluetooth as neither of those options are going to sound very good.  Digital streaming from a quality device dedicated to the task has the potential to introduce you to some truly outstanding experiences far exceeding CD.  Get the Bluesound Node.  It’s easy to use, easy to setup, supports nearly everything you’ll want it to (including MQA) and won’t break the bank.  Right out of the box it sounds pretty good if not a little on the dark side and if you want to take the next step you can do a dedicated DA or feed its digital to your integrated (losing the MQA if you go that route).  It’s a great entry to hi res streaming and easy to sell if you decide to step up to something better.
