The Meltdown/Spectre fix penalizes code that that has a high frequency of system calls. I doubt HQPlayer fits this profile. My Audio Setup Link to comment
juanitox Posted February 17, 2018 Share Posted February 17, 2018 Quote I'm not going to say anything about "sounds better to me". But from objective technical point of view using -2s filter is much better option. You essentially have same functionality (two filter stages instead of one), but without the adverse effects. perhaps less stress on the processor is better , subjectively i prefer to use 2s polisync 44-DSD512 than non 2s version.

Thanks - makes sense, and I like the more specific discussion (high frequency of system calls) vs. the general (without "speculative execution," some stuff will slow down). I think the new power profile available on Win systems probably operates on a different level than speculative execution/branch prediction anyway. It works with stuff like when/whether the computer goes into sleep mode. One never knows, do one? - Fats Waller The fairest thing we can experience is the mysterious.

Jud Posted February 17, 2018 Share Posted February 17, 2018 Well, I selected the power management profile so my computer wouldn't sleep while running a long backup task. But no, not with HQPlayer, which I assume is what we're interested in. One never knows, do one? - Fats Waller The fairest thing we can experience is the mysterious.

Yviena Posted February 19, 2018 Share Posted February 19, 2018 Actually wouldn't higher DSD rates also require higher frequency clocks and as a result also have higher phase noise. Link to comment

Yes, there's not necessarily advantage endlessly pushing up the sampling rate. DSD1024 still works quite OK from clocking perspective, although suffers a little compared to DSD512. But it uses same clocks that most of the recent DAC chips use. Going above that to 100 MHz range (used by ESS Sabre) will have bigger negative impact...

gsquared Posted February 20, 2018 Share Posted February 20, 2018 Question... I've been experimenting with upsampling in HQPlayer to DSD256 and DSD512 and I'm hearing a very audible hiss that I do not hear with PCM or DSD128. I use the Holo Audio Spring DAC KTE + Singxer SU-1 + UltraRendu. My chain is Mac Mini running Windows 10 -> UltraRendu -> ISO Regen -> Singxer SU-1 -> Holo Spring DAC (via I2S). UltraRendu is running as an NAA. I've tested several tracks and when I upsample to DSD256 or DSD512, I get an audible hiss that sounds like analog tape hiss. When I change it to PCM 384K or DSD128, I don't hear the hiss. Anyone have any ideas what might be causing this noise? @Miska @Superdad - Gary Intel NUC NUC8i7BEH Roon Server running Audio Linux in RAM -> Sonore UltraRendu (Roon Endpoint) -> Uptone ISO Regen -> Singxer SU-1 KTE -> Holo Audio Spring Level 3 DAC -> Nord One UP Monoblocks -> Spendor LS3/5as | Music controlled via iPad (Power Conditioning: Audience adeptResponse aR12).

ted_b Posted February 20, 2018 Share Posted February 20, 2018 Gary, are you running native (i.e not DoP) in HQplayer? Is your driver the Linux UltraRendu driver? Have you tried going direct (simply as an experiment, running Windows drivers from Win 10 to Singxer)? It sounds like a driver issue. "We're all bozos on this bus"....F.T.

Were are asking about the driver in the Singxer Su-1. Yes I believe it has V2.20 that was added when I had Tim add the KTE upgrade to it. Is there a way to check? From what i'm reading on KitsuneHifi's website, it's a firmware update... correct?

ted_b Posted February 20, 2018 Share Posted February 20, 2018 Yes, I guess if the UltraRendu is acting as an HQP NAA then it is looking for a Linux driver from the Su-1 (and yes, v2.2x is firmware). Maybe THAT driver (which is no specific driver per se, it is just a Linux UAC2 compliant kernel) is faulty above DSD128...dunno. That is a reason to try going direct, eliminating the Rendu NAA. Then you'd be using Windows drivers. Worth a try, just to begin to isolate. Maybe someone who runs Linux NAA of any sort into a DDC can help. "We're all bozos on this bus"....F.T.
