Priority use for purchasing my first linear power supply - Streamer, DAC or Amp?

Move it around and see what sounds best. Check this out instead of LPS, it works great on my streamer:

Thank you

You could possibly buy a dual output ps or even 3 outputs. Imagine the possibilities and price! 
 

I have an uptone audio JS-2 powering my server and a Etheregen. An Afterdark powering a master clock for Etheregen. These make a nice addition and when I've taken them out and use the stock power supplies what a difference can be heard.
