Ditto the cost shouldn't be a factor in getting into the streaming game.
When I told my son it was going to cost about $1300 to repair my Acurus ACD11 CD player, he asked why I wanted to listen to CD's. So my question was what was he listening to. His answer was "I'm streaming". He was using Tidal and a Node. So I stopped the Acurus repair, bought a Node 2i for about $400 and plugged it it straight into my McCormack DNA 0.5 power amp, bypassing my preamp because it to needed to be repaired, more $$. And with the Tidal family subscription I immediately was getting great sounds. By digitizing all my CD's and storing them on my NAS, my entire local library was even more accessible. And the Node gave me remote volume control which I didn't have with my preamp.
Gradually one can slowly upgrade. First, eventually, I moved to an external DAC, an inexpensive SMSL SU-9, about $500 and worth it.Then a year later I switched the Node over to a Linear Power Supply, added an audio network switch and better quality DC and Ethernet cabling. Over time this doesn't add huge amounts of money and gets quality that could cost much more. And, lastly, Roon and an Intel NUC Core is an incredible addition. I can access everything Tidal had as well as ll my digitized CD's on my NAS. (And all this is available anywhere, like my car, with the Roon Arc iPhone app). Can't tell you all the new music I've discovered; it's an incredible doorway to things you'd never discover otherwise. So over the last 3 years I've spent less than $2K and with the Node alone less than $500. The best moves I've made to my Sound system and dramatically increased my listening time and pleasure!! Start slowly, as much as the budget will allow and see for yourself. If it's not for you, you won't have invested much.
