Specific Node/Airplay question

I know very little about digital and don’t have much interest in it; I bought a Bluesound Node 2i a few years ago to try Tidal but canceled the subscription shortly afterwards. The Node sat unused for years. The other day I learned I can stream Apple Music over the Node; SQ wasn’t great, but it’s coming from my phone, so I wasn’t expecting much. Here’s my question… if I only use my Node to stream Apple Music from my phone, does having an external DAC make a difference? Or, is the music so compressed, that it won’t matter? I’m asking because I’m shopping for a new preamp and considering a McIntosh c2300. But there are C2500s (built-in DAC) for the same price and the c2600 (better DAC) for a little more. The C2700 is too expensive and I don’t plan to ever “up” my digital game; I’m a vinyl guy and this digital stuff would likely be for my wife.
