Where do I go from here?

The choice to go straight to streaming is the right one today. 
 

Streaming can sound better than CDs and equivalent or better than vinyl… but it depends on the price range. Vinyl wins in the <$20K digital leg area (meaning, you have to pay a premium… say 20% more for digital to equal vinyl… ((streamer + DAC vs TT + Phonostage). Over that, you can get equal sound quality for about the same money between digital and analog. 
 

My rule of thumb is the investment in carefully chosen components should be around Streamer = DAC = Preamp = amp… But about 30% more on speakers.

I am hoping this helps point you in the right direction. Given the age of your equipment, you might value it at 1/2 original cost.

Price isn’t everything, but it is a good way to think about how to invest in components to shoot for a very complementary set of components where no component unnecessarily holds back the system.

I had a pair of Acoustat 2 + 2’s in the late 70’s that simply put me permanently in the audiophile camp and began my lifetime pursuit.

I think you really need to spend a few months streaming before you make any serious decisions about streaming or what to purchase...

PSAudio has a generous trial period. Maybe try the spout, it has everything inside and ready to go as a streamer Dac and pre....get a better idea of what you need and keep it or send it back no questions asked.

Yes, it is simple and viable.  You also need a DAC.  Some streamer has a built-in DAC or preamp has built-in DAC.  Alternatively, you can go separate for all components: streamer => DAC => preamp route.
