I have had a few people ask me about my HQPlayer settings and how I get it to up-sample all my music to DSD512. The following screen shots are my settings. I have Roon and HQPlayer both running on my computer/custom built Windows 10 Pro Server. Roon is the controller and user interface, HQPlayer handels up-sampling and is the playback engine. Everything I have is up-sampled to 24.6! This is DSD512 with a base clock of 48.... I am hoping that these screenies make since and give the answers to your questions...
