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

@donjr  If you are asking me I have an Auralic Aries Mini which streams wirelessly from my NAS drive and also streams Tidal. Its connected to my dac with an spdif rca cable. I control it using their remote app Lightning DS on my ipad mini. Very simple and satisfying setup for me and it wasn't expensive in terms of high end audio.

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..
