I don’t use hqplayer, but i do run Roon on Apple silicon Mac mini going Ethernet to a streamer that its function in life is to galvanize the incoming Ethernet to the I2S output to my dac, all running roon upsampled to DSD256.
I used to run the same setup using Roon upsampled and it didn’t sound as good, so I ran Roon on a trash can Mac Pro running Linux and this combo sounded better than running Roon on the Mac mini. Even Qobuz Connect sounded better than both these upsampled configurations. But the upsampled Roon config sounds the best now.
BTW, I had the Cinnamon Ethernet in my system and then upgraded to the Vodka Ethernet cable, sounds better, more than 2x the price and 3x thicker cable. As for the I2S cable, I tried a few cables and ended up with the $1000 Revelation Audio Labs cable
