Streaming for beginner


I have a PS Audio front end-- DMP disc player and DirectSteam DAC. Very happy with the resolution and performance, especially from my redbook cd collection. For those familiar with the DSD, it is upgradable via a network bridge card to become a dedicated streamer. When I bought this DAC, I was looking ahead to an eventual migration to streaming.
I also have a Spotify account, that currently only serves me as a companion to my iPhone during walks and exercise.

My question: assume my goal is to stream for convenience, simplicity, and achieve audio quality that equals or surpasses that of redbook cd’s. I am not looking to purchase music or download it for storage. What am I missing? I also have a dedicated iPad that can serve as the interface to the DAC/Streamer. Spotify also claims that streaming in high resolution is available on my account. Do I need anything else? Am I oversimplifying this?

I am a beginner when it comes to streaming, so please answer in simple terms since I will not be familiar with a lot of the services and components mentioned elsewhere in these forums. In fact, confusing enough for me that it is forcing me to ask here.

In my, admittedly limited, experience Spotify is far behind other two in sound quality. Qobuz was better of the other two.
I have a similar setup as you with a DS Memory Player and DS DAC with the Ethernet Bridge II card. I could be wrong but I think it is a Roon endpoint and not a streamer. Someone can confirm. I have an Innuos Zenith MkIII and Phoenix routed via Ethernet to that Bridge II card. I have an Eero Pro nearby that is connected to an SOtM switch to which the Innuos is connected via its Ethernet LAN port. This is a pretty optimized system and not necessary for a beginning streamer. I think that if you have a router nearby and can either net from it to a streamer if needed and then from there to the Bridge II card you should be all set. If you need a streamer (I forget if you do) then you can get a good relatively inexpensive one and go from there. For high quality Ethernet cabling on a budget I highly recommend the Cat8 Supra cables from Sweden which you can get on eBay. 
I agree with the sentiment toward Spotify vs. Tidal and Qobuz. I like MQA files but I wonder how much of the sound quality is from the remastering process rather than the file format. The system I am working toward is here. Hope this helps!
The DS+NetBridge is super easy and direct streaming solution.  I have the same and stream Tidal to fantastic results.  Enjoy!
Qobuz great! Lot's of high res. Works for me. DirectSteam DAC great too.
