Streaming virgin

@ jbuhl 
The ads say that the DAC is an option. So the OP may not have that option installed. That may be a route to get his feet wet as well, depending on cost. And it may be a plug in option

The cd is the transport. The amp has the dac.  I was hoping to maintain at least cd quality.  I would subscribe to a better streaming service for that purpose. So am I right that all I should need to do is add a stand alone streamer to my current system?  If so is that then just a wifi connection thru an app?  I forgot I also have Amazon HD music service

@dagery

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.
