My suggestion is to buy a Bluesound Node and try it out. It works out of the box (Ethernet or Wi-Fi connection) and connects to your preamp with its built-in DAC. You can also use digital outs to go to your Hegel but not sure if the Hegel does full MQA. You then use your Mac or iOS device and just use the Tidal app and stream via Tidal Connect on the Node. When doing that, the app is just telling the Node what to stream. You can also use the BluOS app to stream Tidal or Qobuz, etc.
I’m fairly new to streamers too — just got the Node for Christmas — and very happy with the SQ and ease of use. I also like that I’m not tethered via a USB cable to my system. All that said, I do still use my IPad connected to my DAC as another digital source. That let’s me play with Apple Music and Amazon HD.
