What do I Need in Order to Stream digital content and Store & Play CD's ?

Thanks for your patience guys. I have not ripped any cd's yet, nor am I streaming any audio other than Pandora-through my Sonos.
So, Ok, listen. I am an old guy. I have a splendid old guy system with digital in the form of CD's played via my described PS Audio Lambda transport & Classe DAC. Because I enjoy Pandora, I now want to stream cd quality audio via Tidal (because I understand its the only service with hi fi quality sound). I also want to store my CD's digitally and play them. My question is, what are the best devices and means to accomplish this goal?
Thanks to jond,donjr& sbank for your patience with my doddering attempts to communicate my questions!

I'm right there with you Michael. Thinking of trying Tidal through a current usb DAC via my PC and the terminology used by the experts (ie NAS, Synology or QNAP) is confusing to me.

I think we may need to find a "Streaming for Dummies" book. lol

Best to you Michael,

As Dave said, you can stream Tidal from a computer. Also playback CDs as uncompressed files. 300 CDs would take about 150 GBs hard drive space. Do you have a computer and if so what make? I use a MAC mini in my main system and also a Macbook pro for my secondary systems. With a computer using USB you would only need to get a USB to SPDIF converter for your DAC.

Good luck!

True that! I have a friend my age group who is a long time computer nerd and he is impatient with my ineptitude, I'm just trying to catch up enough to communicate with him! Puts like learning a new language of acronyms..
