Digital streaming options for my system are confusing


I appreciate your advise in advance as I am more of a old school vinyl/cd guy. I have a McIntosh MAC6700 integrated receiver. It has a DAC but tech in this area is evolving at such a rapid rate that I am confused as the best way to access a high audio quality streaming/digital playback source. I have heard hi end streaming services (Tidal?) are great but my Amp does not have a direct iPhone/iPad connector. What is the best way to go that will keep my system simple and easy for the whole family to access?

Or you could use the Internal DAC in the Node2i for MQA and the current DAC for everything else.
If possible, I would use a wired connection.  I had some issues with WiFi and Bluesound and the Ethernet works much better, but the Node 2i is supposed to have enhanced WiFi capability, so hopefully non important...
Does that matter for high end streaming? or only specifically for large digital files stored on my own storage
Something worth mentioning if you are going with the Bluesound ecosystem. The Vault is a better option if you want to digitize a CD collection AND stream music. When I bought the Node 2 I had many CDs ripped with ITunes which created file folders and album artwork (metadata) that Bluesound would not see. I had to place artwork into many of those album file folders and properly label the artwork. https://support1.bluesound.com/hc/en-us/articles/200271926-Why-is-some-of-my-Album-Cover-Art-shown-a...
Ok, so I did do the album artwork thing when I burned my CD’s. Does that have any impact on anything unless I have a laptop/tablet open when I play? Seriously, Im just a 48 yr old trumpet player trying to make things easy for everyone and sound really good to me when I have a few moments to myself.
