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?

If the 6700 has a USB input it is likely an early version that if I remember correctly was limited to 24/96 max so the innuous is probably overkill on that amp.
Could be totally wrong of course but my McIntosh with built in DAC that looks very similar input wise to the 6700 was limited to 24/96.
I checked my owners manual and the optical and coax are only to 96 but via usb it does handle up to 192. I am willing to invest to optimize so are there specific cables and other details I should consider?
32-196 kHz at 32 bit. I am doing my research but should I be focused on the 32 bit stream capacity
+3 for Bluesound, and you can use an external DAC with the Node.
Also nice is you can sync multiple systems in your house.
