I would add a Bluesound Node 2i which will give you streaming as well as Bluetooth, airplay etc - it'll work great in the context of your system.
I wouldn't personally buy an amp/dac/streamer together as digital is moving too fast - better to have a good analogue only integrated like you already have and add a relatively inexpensive streamer that can easily be changed or upgraded at a later point in time.
