Not really. There are examples of HQPlayer being run on low powered devices as an embedded version but it kind of defeats the merits of the software. And while you could potentially do this on something like a Qnap server I cannot imagine the results would be great. You need an additional PC and the more powerful the better.
I am going to just say “No, not worth your time”. HQPlayer is built with a goal of using powerful CPU AND GPU processors to calculate very math heavy filters in real-time. Any of the filters/modulators you read people on the forums praising would not work on the NAS.
But I wasn’t generalising. If I wanted to do heavy stuff HQPlayer would be my first stop. For lightweight stuff I can probably get that done without having to pay out for a licence. I’m not against HQPlayer, I just don’t see much point on a Celeron processor.
I can attest to the success of using the Mac Mini M1. I have it feeding a Holo Spring 3 KTE with DSD512 using Sinc-S AMSDM7 512+fs without hiccups. Of course, I am not using it for anything else. I am also using a Jcat USB enhancer.
