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.

I wouldn't worry too much over the mixed reviews. Always good to keep in mind one person's bright and forward is another's neutral. It's your ears that matter. It's the same with every component/speaker/software out there. Enjoy the 30 day trial, you may find the network card is the perfect solution for you.
Don't waste money! There's not a ton of magic in digital data transmission. A lot of this is marketing... Gear makers want to sell their overpriced stuff. No reason to spend about $1,600 total.

@ghjuvanni has a point. No need to even spend $1600, there is Bluesound Node 2i for $550 that will satisfy most users :-) 
Don't believe all this nonsense about how easy this streaming is .
Dropping a pick up onto a record was easy - digital streaming requires a significant amount of effort to get an equivalent SQ.
OK so you jump in with either TIDAL or QOBUZ
Now you really should consider ROON- Infinite number of options in the DSP settings which will keep you busy for months
I choose to have  a dedicated laptop -lots of RAM and windows 10 cut back to bare bones configuration + dedicated LPS
Lets look at our router  , need to hard wire to laptop with Cat8 ethernet cable as a minimum + dedicated LPS
Now special  USB cable to ensure integrity of digital signal is not corrupted before converted to analogue in the DAC -of course make sure DAC is MQA compliant if opting for TIDAL and of course own dedicated LPS
At last we have an analogue signal to be amplified  via a power conditioner like a AQ Niagra 1200 and AQ power and interconnects.
Get those cables off the floor and room correct with DIRAC
Phew now lets listen to some music.
