How important is an LCD screen on your streamer?

I don’t want it. I don’t even want an LED light! My streamer has no buttons or lights and I simply use my iPad.  Remember, that display screen, additional processing power and even LEDs can introduce noise into the system.  These  features require additional power and if not on is own individual power supply it will suck it from the main power supply and introduce noise. 
 

Now the unit can be built with a separate and isolated power supply for these features, but this will cost and many manufactures won’t want these increased costs. Something to consider when shopping.  I am sure some higher end units take care of business and do this right.  Innuos now offers these features in some of their new Stream units.  I bet they do it right. 
 

I would rather not spend money on these features built into a rectangular box 10-15 feet from me 😳. I understand some would love it. 

Not important to me

I wanted screens on my streamers. I thought it would be cool. The only streamer that I have setup thus far is the  Wiim Ultra. I hardly ever look at it. I usually just look at my phone. The screen on the Ultra just doesn't seem practical for control use.

I also have a Holo Audio Red and a Bluesound Node Icon for other systems that I haven't setup yet. I have a feeling that it's  not going to matter whether they have a screen or not, but I still think the screens are cool. I don't have any thoughts at the moment as to whether there is a noticeable noise difference.

For clarification noise is not referring to hearing a buzz, hiss or some noise through the speakers or mechanically inside the unit. Noise in my example simply refers to obscuring the signal and letting other artifacts through that smear the signal.  A simple test in a reasonably resolving system is to turn off as many LEDs, displays etc… that your system allows and listen over time. I have certainly heard it over the years. Some may not as with everything audio it is subjective to gear and listener. 
 

Aurender has a Critical Listening mode that turns off the display for improved sound. It does and I keep it off.
