System bottleneck?

So are you saying I could use a better streaming device than the marantz?

What is your system not doing to your satisfaction? 

I knew I would get that question. I cannot say there is anything in particular but like a lot of us I was just looking for that little bit of extra. For example I thought someone might tell be to get an outboard DAC that is better than the one in the marantz. Or a better streamer than the marantz. Conversely I did not expect to hear anyone say to get better speakers because I feel the speakers are the stars of this system. But to be specific I am always looking for better clarity, bigger soundstage and more separation of instruments. Those are my typical goals. 

Streaming through your phone is the bottleneck. Why are you streaming from your phone and NOT the Marantz when it is also  a network player?

Heres the description
