Can Streamed Music Sound Better than any other source?


I am about to make the leap. Jumping into a Server or is it a Streamer? To use existing DAC-Oppo 203- or upgrade? I love the concept of access to all the music on line. So I don't actually own any of it-thats fine. Buying downloads adds up quickly. $20/month sounds like a bargain.  Roon's system looks appealing. I can add Tidal and be done, right? I get a lot of great counsel from my old school expert at the HiFi store I support locally but he can't even spell stream.
I was born in the 50's and want to use this listening option now. As this technology is still evolving, I am not inclined to overspend on gear that may be as valuable as a VCR in a year or two.
In the end I want to know if I can have this new source sounding better than CDs and LPs. I am not going back to reel-to-reel so if that is best source, please ignore it as it regards my purposes.
Thank you. I look forward to learning from the responses!!

I would say that is a matter of opinion as one who has given up turntables and never looked back. My pal has a turntable that cost with arm and cartridge over £40.000 and at a tenth of that price I am listening to 24/96 streams that are every bit as detailled as his and not a tenth of the bother.
Thanks to everyone who had an opinion and was willing to share it.
I am at the crossroads of choosing which source to upgrade. For now
my downloaded thumb drives are by far the best source I have.
This is why I lean toward trying streaming. I don't think I want to start
building a great Phono system when it can cost $50 to buy one quality
LP. I will read up on past threads but it seems this is a somewhat evolving technology so going back too far may be less useful.
Just be sure to consider streaming from your files as separate from streaming from online services. It's w shame that common vocabulary doesn't have two different verbs to distinguish between these. Driving your Lamborghini is quite different from "driving" a skateboard! Cheers,

Not sure if it is better than vinyl or CD, but when the BBC stream live classical concerts, the sound even through a cheap as chips Bluesound Node streamer sounds rather good to me.
