Tablet contol to cast from net attached DLNA server?

[Donovan]

I have network attached storage that is also a media server. I want to access the server from my tablet - no problem but I want to "cast" the audio to a receiver.

The hardware devices I have used to connect to the media server to the receiver require a TV.

I want to manage the media server and the receiver from my tablet - showing the lists, art, etc. on the table and listening to the music from the receiver.

I have tried the following hardware WDTV, Chromcast and Roku along with several variation of software "remotes".

Is there a single user interface / app that allows me to access the media server and then either cast the audio to receiver or tell the media server to send the UI to the tablet and the audio to the receiver.

Note this is high end old audio receiver and I do not use any of these components for video.

There are plenty of Apps like BubbleUPnP for Android that can stream from a server to a client using the App for control.
