jRiver id for FLAC storage and playback?

Hi,

I am looking for the simplest possible solution to run jRiver and store my FLACs, using either USB or optical output to my DAC.

I need to be able to control the jRiver player from my iPhone, and easily browse my library.

Ideally, I’d be able to stream tidal from the device as well, but not a must have requirement.

What is the simplest way to do this, short of connecting a Mac or PC to my DAC?  I’d like something simpler than a computer if possible.

The jRiver id looks simple and ideal - thoughts?  Could I somehow stream Tidal through this device?

Or do I need a Mac / PC for what I want?

Thanks
