In answer to the OP. I’ve streamed from my PC, and posted a thread myself asking if a streamer would be any advantage. The consensus was no.
But here’s what I’ve found. There’s too much DIY and too much faff with a PC. You could do with looking up entire threads full of argument, counter-argument, disagreement, etc., about exclusive mode, Windows, drivers, and so on.
EqualiserPro? Good luck if it works, lots of people have had issues.
Any you’re tied to what you need to put your PC, which can be an issue.
A good streamer should be plug and play. I have a £90 WiiM Mini and it completely sidesteps every issue I have streaming from my PC.
And guess what, whilst it’s currently a bit shoddy, there is a Windows app for WiiM. So, if you want to sit at your computer desk and use your PC to control your WiiM, you can.
Each to their own.
