I’ve got a Pontus II with a node 2 and added a separate power supply for the node because it was an easy upgrade. IMHO streamers are streamers if you are just doing tidal (that’s all I do). If you had NAS or usb connection it might matter more. So do t over think the streamer and bluesound ain’t going anywhere and supports all the stream services.
so put all your money into the best DAC you can find. Any DAC that has a streamer In it has some design compromise. If you are going for max SQ and you have the budget (you do) then separates is a must not a choice.
