Music Server vs PC confused


Hello hope all are well. 

Current System:
usb hard drive into mini pc (foobar2000) into usb isolation device into Chord Qutest DAC
DAC is into Primaluna evo-300 integrated tube amp into Goldenear Triton 1R   most cables synergistic research

Main Question:
Is a music server/player really worth the cost over a PC?   It seems these devices cost almost same as my amp for what still seems to be a pc sort of device with better power supplies?   

If the answer is yes, please give your valued opinion on why.  Also, what would be a non break the bank device?  I don't need a ripper or a dac in it, or internal storage.  

Thanks Much!!

Thanks all for assistance.  I have decided to try a Lumin U1 mini.  Found a good open box deal.  
Mlapenta, please let us know your experience once you've gotten the Lumin cranking in your system. BTW, I am a Lumin fan.

Great choice, post your feedback once you’re settled with U1. 
Well I started as skeptic, but whomever said there is not going back, was absolutely correct.  The Lumin U1 mini made a bigger difference than i had expected over the old pc.     My implementation is a usb harddrive as input and usb output to my chord dac.   I will note that I have a intona usb 3.0 isolator in the path between the U1 and Qutest dac.  

Lows are tighter, there is more soundstage, and it seems that the mids particularly vocals have a little more "space" around them.  Great product and the app for the Ipad works great.
