Sure, I'm owning since a longer time the Red, the May and HQPlayer.Do you own the Holo Red? It supports DSD1024 and PCM1536K.
Sure very intensive filters should be running on HQPlayer Desktop, which can then be transfer via NAA to the Holo Red.
And if you own a Red you should really compare the Red OS vs. HQPlayerOS which makes a difference in sound quality. Also many users report about that in the main thread over at Audiophilestyle forum.
Also used different distributions (RedOS, Ropieee, Jussi's NAA,...) for the Red.
And surely my HQPlayer is installed on a dedicated PC with an Intel i9.
Mostly I'm using upsampling (and filters for some cans) to DSD256 or DSD512, but for me (again) it don't makes sense to install an embedded HQPlayer on the Red. That's all, what I've written...
