want to get up and streaming with all new gear, please help

Hello everyone,
origianlly i guess I am looking for input on the best way to connect up a Blue sound Node 2I and a BC E1X integrated amp w/DAC.

but I’ve been out of the loop so long I’m lost on the finer points of streaming, ROON, etc. and not sure if I even need everything I bought to do the trick.

I do not have a ROON subscription as of yet but if needed….

I have several personal confusers including a MAC desktop which has an AQ Red dragon USB DA. a new 15:” Alienware laptop. a couple dell desktops. the Blue Sound Node and the Bel Canto E1X w/on board DA.

as all of the home audio items are new, i’ve not connected anything to anything yet apart from ethernet cables and one pr of analog ICs. not even powered anything up.

i did install the Blue sound app on my iphone and I believe BC has an app called sEEK I probably should install too..

is the BS Node necessary for streaming and NAS file playback given the Bel Canto’s dA digital feature set and numerous digital interfaces, or was that purchase senselewss?

I got the impression the BC INT ether net interface was only for firmware updates but I could be off on this point.

i have a synology two bay NAS with about 70K mostly lossless files, sevewral USB thumb or powered drives loaded with redundant file bacups, subscriptions to Apple music and Spodofy.

i use FUBAR 2K for file playback on both Ms and MAC platforms.

I intend on trying to acquire a higher res streaming service ala, geaser, Tidal Ammazon, or possibly that french outfit if any or all are supported by my present hardware. i suppose if one is not supported perhaps ROON might come into play.

i’m thinking too I’m gonna need some new cables as the only one on hand is an Oyade BNC.

Any EXP in this area would be sincerely appreciated.
thanks much!!
