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

Read the 2part Sonore microRendu review on computeraudiophile site before you do anything. I agree with @jond that ripping your CDs, storing them on a NAS(e.g. Synology or QNAP) and streaming to your DAC is the way to go. Don't let any unfamiliar terminology deter you. It's not that hard!!! It's so much better sounding than most PC or Mac based solutions. Cheers,

So if you're streaming wirelessly, what device are you using? I would also like to get this straight. So you have your CD's ripped and stored on a NAS. What's connected to your DAC that allows you to stream from the NAS or does the doc allow that wirelessly?

@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,
