I use a Bluesound Node connected via coax to the DAC1 in my McIntosh MAC7200. Bluesound's coax connection bypasses it's internal DAC enabling me to use the MAC's internal DAC and features. It sounds great.
The Bluesound interface / control is via my iPhone and is very stable and easy to use. My Bluesound node is connected via Ethernet to my router.
My paid streaming services are Amazon Prime and SiriusXM. Both are native to the Bluesound, so I'm not streaming thru my phone. The Bluesound also has iHeart, TuneIn, and others that don't require a subscription.
My next big upgrades will be a Mac DA2 and an MS500 streamer.
Your C2700 uses Mac's top of the line DA2 - enjoy!
