Say what you will, but when I disabled Internet (gateway proper only for Home LAN) on my HQPlayer’s PC (which I stream to - from Roon core on Mac) I’m sure that it sounds better.
I want to stress here that network load to Internet was before disabling theoretically NONE during playing music!
I don’t know why, I don’t understand it - but it is.
It means that net optimization (between Roon and HQP) may be a key question…
I haven’t found topic about net optimization.
