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?

Audiotroy- yeah that is good advice. Also, tricky how you offer great advice on the forum and can slide in a sales pitch for business. Arrogant, but I am sure you get a bite from time to time. Maybe you could pitch your customer service and terms and conditions as well.
