If Roon appears to be playing but HQPlayer not, then Roon is playing to something else than HQPlayer… Because Roon gets the playback position information from HQPlayer…
But for Innuos, you need to ask them, it is not officially supported by HQPlayer.
I’m now using the Holo May and not having any problems with Innuos Pulsar. Must be something with the Diablo 300 DAC.
I’m no longer using a Mac mini M2 Pro. Now using an M1 16gb. It seems to be able to handle DSD256 with ASDMSEC-light and DAC correction.
I don’t understand the 265.1%, but the overall CPU usage seems to be a modest 40%.
Importantly, how does it sound for you on MAY, @Steven44 ? And MAY is in NOS mode ofcourse, correct?
Correct, it is in NOS mode. I’ve just posted a detailed observation in the “show us your room set up“ thread and explained sonically why I went back to the May DAC.
(For some reason my posts have to be approved, the other post will be up shortly I presume)
This means “worth 2.65 cores”. IOW, having one core worth fully loaded is 100%, having two cores worth fully loaded is 200% and so on. This is standard Unix “top” way of reporting loads. So one single-threaded process could use at most 100%. You also get 100% load if two cores are loaded to 50%. Or 200% if four cores are loaded to 50%. So 8-core CPU has theoretical maximum load of 800%.
Hi Jussi，
May I ask, at this point in time, which has a better value, the Mac Mini M2 16G or the Mac Mini M2 Pro 16G to run HQPlayer?
The basic model should be able to do default settings to DSD256. For anything more, the M2Pro model provides more performance. Or if you’d like to run anything else on the same machine, such as Roon.
I was using the M2 Pro, now use a M1 16gb as it runs DSD256 + Holo DAC correction + Roon Server no problem at all.
Hi! I need your help with settings for my new purchased HQPlayer to use with ROON.
My system includes Apple MacMini M1 (I’m going to change it to M4 Pro) and CONOR CD 1.10 (uses the Texas Instrument PCM1792 (24/192) chips, one per channel).
Just now I’m using default settings.
Could you, please, give me some tips on what I can change in settings for best performance?
I would configure HQPlayer to output DSD256 if possible (SDM output mode and 44.1k x256 bit rate limit), otherwise DSD128. Since direct connection with Mac requires using DoP, I’m not entirely sure if DSD256 works in that case, but based on information I found I would assume it does. It is a very nice DAC chip for DSD use cases, since it is always bit-perfect conversion with DSD.
I recommend using for example ASDM7EC-light modulator (also -ul, -fast and -super are possibilities, but in particular -super may need M4). Default filters are very good for wide variety of content (1x = poly-sinc-gauss-long, Nx = poly-sinc-gauss-hires-lp). But I recommend to take a look at the filter table in PDF manual for some potential other options.
Thank you very much for your reply.
I’ll try and follow all your advices.
But, with your permission, I’d like to ask you more questions.
Your HQPlayer is wonderful, I’m enjoying to listen music with it.
But I have a problem. Every time I’m launching your HDPlayer, there is an inscription on my screen.
When I press OK, next everything works.
I think, I’ve given every possible permissions in settings.
What I have to do to rid of this problem?
And one more question.
In my CANOR CD, there are two non-deactivating filters, DYNAMIC and NATURAL.
Which of them better to use?
My MacMini connects to CONOR CD via USB cable.
This is the one missing:
Microphone = any audio input, not very logical, but it is the same on Windows too…
I think these refer to the two PCM oversampling filters in the DAC chip, not applicable to DSD playback. The chip has four different analog conversion filters for DSD, but likely there is no control over those.
Thank you very much!
DSD256 is Ok, everything sounds better now.
In the Output device settings, I have to mark 48k DSD?
When marked, the system works. But is it necessary, or not?
It should be marked only if you are absolutely sure the DAC supports DSD also at multiples of 48k. Most devices don’t, so it is safest to leave it off. To make use of 48k DSD you would also need to increase rate limit to 48k x256. When 48k DSD is not available, keep “Adaptive output rate” off.
I tried settings from those pictures
Sound is like from vinyl.
When Adaptive rate is on, system doesn’t work with any other settings.
First thing, please select your DAC instead of “Default” and also check that your DAC is not set as default output device for macOS.
Please uncheck “48k DSD” unless you are absolutely sure that it will work. Please also set 44.1k x256 as output rate limit, and that Adaptive rate is off. And Modulator to for example ASDM7EC-light. Please also check that your HQPlayer volume setting is not higher than -3 dB.
Thank you for your time.
I followed your recommendations, and now, my settings look like this:
My system keeps going, and I’m satisfied with results.
Please, could you look at these pictures of settings, and give me your opinion 
Input backend should be set to “[none]” here.
Uncheck the 48k DSD here.
And here set bit rate limit to 44.1k x256.
When using Roon as source, I recommend setting Idle Time to 10 or 30 seconds. I personally use 30 seconds. This makes Roon interaction much snappier.
Thank you very much Jussi!
It sounds amazingly now!
I’m able to hear it because my system includes (besides CANOR CD 1.10) an amplifier Unison Research Performance Anniversary and loudspeakers DeVore Fidelity Gibbon X.
Best wishes
Love it. I have the Devore Orangutan o/96, and I find Devore is revealing enough to make the most of upsampled content. And I’m still currently just going to PCM192 into my Yggdrasil, waiting for a Holo Cyan 2 and Mac Mini 4 to really see what I’ve been missing through these speakers
