Limits has stayed at 0 at all times with Direct SDM disabled. Still get pops even at -30dB fixed volume, listening to Keith Jarrett streams on Tidal (not compressed).
I noticed as I was screen sharing with dad that DSD512 started off ok (listening to quiet Keith Jarrett Tidal stream to pickup pops easily) until I started browsing his Roon library on his Mac…
i.e. when Roon Core starts doing more work (on the same machine as HQP Embedded of course), and CPU usage (and network usage?) goes up, the pops with DSD512 become much more apparent.
When I next visit him I’ll take the sonicT i7 from the home office and into the listening room and connect it via USB directly to the Pro-Ject S2 , i.e. by-pass ultraRendu, for testing purposes.
@jussi_laako - until Jesus can test a sonicT i7 himself (or someone else that comes to read this thread), have I run out of things to try in HQP config?
@andybob - are you running Roon Core on the same machine as HQP? Or separate machines? If both are on the same machine, what are you machine’s specs and can you run the 2s filter variants at DSD512 without issues, with the single Roon Core + HQP machine?
