How important is an LCD screen on your streamer?

And I don't know what you're talking about with regards to Aurender. They have some of the biggest, clearest screens on the market on all of their products. That said, as others mention, they have options to turn them off, and most people do this because of the reason I state above.

Yes, Aurrender has a switch that makes the screen turn off whenever the music is playing. Great feature… vs just always off. 

The screen isn’t particularly important to me when streaming because I use Roon.

An iPad serves as a control point and a TV on the wall between the loudspeakers displays what’s playing and a picture of the artist.

It’s a very nice feature.  
 

I have a Cambridge EXN100,  it has a very nice screen. It gives lot of information and makes the system look more interesting,  doesn't look like just another black box.
