Jussi…..thanks for your input. I removed my switch and it did seem to help a bit initially as I was able to go past a minute before the dropouts occurred again. I tried to change filters and modulators thinking if I found some less demanding, I’d be good to go. Eventually the dropouts returned after a few seconds of playback regardless of filter or modulator selected. Rebooted the Mac seems to help the issue with dropouts for a while. I’m running an Ethernet cable from my router directly to the mR. An additional Ethernet cable is connected from the router to the Mac. All dust was removed from the Mac’s vent. Can you suggest anything else I can try network related?

I could use some help. After a 15 month hiatus from audio, I’m back listening. I’m still using HQP4 and currently running version 4.20.2. I’m also using a mRendu 1.4 with Sonicorbotor 2.8 and NAA version 4.4. I’m using a M1 MacMini with 8G of RAM and have zero issues with DSD256 playback. DAC is a Denafrips Pontus II. I’m currently using poly-sinc-gauss-long and ASDM5ECv2. I can use any poly-sinc filter without issue as well as 7ECv2. For some reason, I can now only playback up to PCM384. PCM705/768 plays for 15 to 30 seconds and dropouts start to occur. Prior to my hiatus, I was able playback PCM 768 without a problem and 1536 occasionally. I’ve been told that if I can run DSD256 without issue, my setup is likely causing the issue. I’ve also tried older version of HQP back to 4.17.2 with the same problem. Any ideas on where my problem may be when trying to playback higher rate PCM?

I've recently noticed that I've lost the functionality of "gapless playback" while steaming music from Qobuz 6.0.4-b017 which I believe is the most current version. Locally stored music continues to play gapless. I'm currently using Roon 2.0 for library management. I just updated to HQPlayer desktop 4.20.2. I did update my HQP NAA to 4.2.5 a few weeks ago and only guessing here but doing this may have been the change in my system to cause the problem. Is there a way to revert back to a previous version of the HQP NAA? I'm currently using a MacMini M1, a MicroRendu 1.4, and a Denafrips Pontus II listening to DSD256. Other than the loss of gapless playback with streaming Qobuz my system is functioning perfectly and sounds great. Any suggestion to remedy my issue would be greatly appreciated.

Roon DSP has been disabled and I am using the ARM64 version of HQPlayer 4.18.1. I believe went back and I've tried HQPlayer versions going back to 4.16.0 all with the same results. Background activity are Throttled. Output from the Mac mini M1 goes to a MicroRendu 1.4 -> Denafrips Hermes DDC -> Denafrips Pontus II DAC. I tried using the HQPlayer client 4.18 bypassing Roon and I also experience the same dropouts. The Hermes DDC seems to have been the culprit as once removed the dropouts have disappeared. Do you have any idea on what the DDC is doing to cause the issue? I will contact Denafrips. Thanks Miska....

Prior to the previous Roon update, I was able to play DSD256x48 and ASDM5ECv2 or 7ECv2: 1x - poly-sinc-gauss-xla Nx - poly-sinc-gauss-long or any of the newer poly-gauss hires versions Since the update I've lost the ability to play any poly-gauss options or poly-gauss hires versions without experiencing dropouts with hires content. 1x - still plays poly-sinc-gauss-xla perfectly after the updates for redbook. I've updated to Monterey 12.3.1 and the new Roon update this morning with no changes. I've believe I've tried every conceivable option with Multicore DSP and Adaptive output rates. Setting Buffer time to 250 ms seems to help but I still experience an occasional dropout.

Thanks for those who responded. I did try rebooting my NAA but it did not remedy my issue. Just to clarify playback is perfect, it's just when the next track is loaded in the queue, that I notice a "click, pop, or dropout". This only happens playing Qobuz directly to the HQPlayer client. If I use Roon with HQP, I do not experience any issues.

Hi Crom, I believe experienced the same problem that you describe the other day. If your OS is Big Sur, you need to upgrade to Monterey if running 4.15.1. Denis

I updated to a MacMini M1 yesterday coming from a 2018 MacMini. I updated from Big Sur to Monterey running HQP 4.15.1 and am able to successfully play DSD256 -> ply-since-gauss-long -> AMDSDM7ECv2 with Multicore DSP fully checked without any real issues. I'm also using a MicroRendu. I'm currently using Qobuz direct with HQP without using Roon. My problem is that at the end of a track, while the next track starts to load, I get a "click" or faint "pop" which is caused by the next track loading into the queue. Using my previous Mac playing DSD128, this anomaly happened occasionally but with the NEW M1 Mac, it happens 100% of the time. Using Roon, I do not experience this issue. Has anyone else experienced this and is there a setting that needs to be changed?

I’ve solved my issue when upsampling to DSD512. I read on another forum that someone was able to get DSD512 and A+ to run flawlessly on a late model Mac with a mRendu. I ended up moving a newer 2018 MacMini from another location to my music room and switching out my late 2012 MacMini. I’m only running 8GB of memory compared to 16GB on the older Mac but now have zero issues. Using a mRendu 1.4 as a renderer.

I’ve got DSD256 up and running with zero issues. I believe a setting in my SonicOrbitor was the issue. Something to do with enabling direct DSD support. DSD512 plays and sounds fantastic except for the occasional stuttering. According to A+ they do not confirm or deny if I should be able to play and upsample DSD512. I’m confident that I am playing DSD512 as it is displayed on both DAC and in A+. Audirvana is asking me to try removing my mRendu from my front end chain and to plug the DAC directly into my MAC. My problem is that the El Capitan OS is not supported by the Project S2 DAC. I’d be over the top if DSD256 was the best I’ve heard in my system as things are functioning perfect at this sampling rate and it is a clear upgrade in sound quality from my previous 24/192 DAC. I wish I’ve never heard DSD512 as it’s clearly superior. Happy for now but I hope someone can offer a remedy without going to a Window based computer as Jud has stated. 😩

I recently upgraded my 8 year PS Audio PWDII DAC to a Project S2. Primary reason for doing so was for its ability to play upsampled DSD512 files as well as fully decoded MQA files. I could not be happier with it's performance. DSD512 sounds magnificent. MQA as well but the surprise so far is that DSD512 sound better to me. My music server is a late model 2012 Mac Mini with 16MB of memory. I’m also running El Capitan for its OS. The reason for my post is that I need some advice and help. When playing the first track of upsampled redbook files to DSD512, I get a stutter. I get occasional stuttering during a track and usually again at the beginning of the next track. I’ve tried different settings in A+ focusing primarily with “memory allocation”, and sampling rates. All adjustments change the timing and rate of the stuttering but I cannot find a remedy for my issue. PCM up to 384 has zero issues. Another thing I noticed is when I move the sampling rate in DSD to DSD256, A+ accepts the change but the file playback sampling rate on the remote and at the right side bottom of the screen in the desktop app displays 16/44. I’m assuming that I am not playing back DSD256. What am I missing here? I was thinking that perhaps a new MAC with a faster processor would possibly be the fix but after reading this thread, others with newer and faster computers seem to have the same type of issue. Can anyone out there play DSD512 seamlessly without glitches or issues? If so, can you please share your setting or suggest something to try? DSD512 sound so good, I’d hate to playback and settle for DSD256 if that is even possible. Thanks and look forward to some ideas and feedback. Hoshi

I'm surprised that no one has mentioned the Supra 8. I gave them a try due to the very positive feedback I've read here and on other online reviews. In the past I've only used generic cables both shielded and non and found the Supra to sound excellent. A bit polite and laid back initially but overall delivered a well balanced presentation once settled in and more likely me just getting used to the change. Come to think of it, after adding these cable to my spaghetti front end things sounded so smooth that I finally did a bit of surgery on my Maggie's crossover and bypassed the fuses. Not dirt cheap but not crazy expensive. In fact if you need a long rub, Supra sells their cable in bulk pre-terminated packages. Hoshi
