I think I found the problem:
As for profile “REW Adjusted,” I upload separate files I created with REW when plotting.
As for profile “STAX SR-L700Mk2,” I copy the code you made for me before directly into the “process” boxes (Left and Right) and plot them.
I think the mistake is there, the last one is named “iir:type=lshelf;f=71;s=0.25;g=-4.2” but the process-entries for that one are empty…
Ummm.
I started over by deleting all profiles and creating the two profiles again, but it still doesn’t work.
Well, I save the files where it’s easily accessible, so I can do it manually, anyway.
That “iir:type=lshelf;f=71;s=0.25;g=-4.2” should go to the “Process” entry, not to the name of the profile…
I fixed that.
I think it accidentally became a profile name due to autofill.
But even after the fix, it doesn’t work for some reason.
Both of those have empty “process” entry. Is it not getting through from the browser, if you filled up those there before saving?
You can also just manually place it there… Then do “systemctl restart hqplayerd” if you modify the configuration manually. Because otherwise the changes will get lost next time HQPlayer saves the file.
Is it okay if I fill the process entry with “1”?
Or does it have to be something like “iir:type=lshelf;f=71;s=0.25;g=-4.2”?
Sorry, I didn’t get this.
It needs to be something HQPlayer understands. If you fill it with “1” then HQPlayer will spit out a parsin error in the log file as it cannot understand what that means.
I assume this is something you are trying to do, before clicking “Save”, but it doesn’t work?
It doesn’t.
I don’t know why.
For example, I start with the following profile. This one is generated with a REW file.
Then, I select and load the saved file, which you’ve seen today, and get the following.
Then, I check both boxes for “Plot,” then press the “Plot” button to actually get the curve.
So, perhaps it wasn’t supposed to plot the saved profiles automatiacally.
If so, it was my misunderstanding.
Still, I may need some help to write the “Process” line.
I’ve seen some posts on the forum before for writing the REW configuration in one line, but I don’t know how to do that.
I’ll search, though.
It plots only once you select what you want to plot, and click the “Plot” button. Until then you see just what has been plotted before. So, yes, it is not automatically updated, only once you ask it to.
Please check the Help-page for the syntax. But it is pretty straightforward, also if you do for example headphone correction from Oratory1990’s PDFs.
I recommend to get started with text editor like Notepad and first type each EQ segment on separate lines. And then when those are ready, concatenate the lines with comma (no spaces). Then it is easy to copy-paste there.
For each entry, syntax is plugin name, “iir” in this case, followed by colon. Then each parameter followed by semicolon. Like:
iir:type=peak;f=1000;q=0.707;g=-3
Where type=peak specifies the EQ type, f=1000 tells the frequency is 1 kHz, q=0.707 defines such Q value and g=-3 specifies -3 dB gain. You can have as many such blocks as you like, comma separated.
Jussi,
I finally succeeded in saving/loading the profiles.
It is convenient.
Many, many thanks! 
So, I’m brainstorming how to build an upgraded HQPlayer OS machine.
My current machine is Skynew K9, due to the limitations of my current DAC and processor, Accuphase DG-68. (supports only up to 192kHz)
I will probably get the Holo Audio May DAC in January, so then, I’ll be able to enjoy higher upsampling and DSD playbacks.
I’m not sure which CPU brand works better for the purpose, Intel or AMD.
Any suggestions?
What is your desired output rate? Which settings? Are you planning to get a GPU for offload?
At the moment good baseline for system without GPU offload and stereo output is i9-14900K. For multichannel cases AMD CPU may be more interesting (offers more P-cores).
I will post test results for Arrow Lake CPUs as soon as possible. But the most recent release should be very perfectly fine for these too.
Does it mean that your latest HQPe 5.9.2 works well with Arrow Lake CPU?
Will this require any update kernel?
I have tried to disable Hyperthread on my Raptor Lake 14700K and run HQPe 5.9.2 Intel version with your 6.6.50-jl+ kernel but it did not work well (CPU core allocation distribution not optimised).
I’m curious if disable Hyperthread on Raptor Lake will help to reduce power and heat similar to Arrow Lake while maintaining reasonable performance
I expect some improvements once there’s a new LTS kernel. But from code point of view latest HQPlayet Embedded and upcoming HQPlayer desktop 5.9.x should be good.
I don’t see a reason to disable HT, as it will just decrease performance without winning anything. Right now HQPlayer is utilising HT feature to the extent possible. I would never consider disabling HT on Arrow Lake either.
Heat and power as such is not an issue, implementing enough cooling to gain maximum performance is. That’s where Arrow Lake is supposed to help, with less demanding cooling solutions. Because keeping i9-14900K out of thermal throttling needs some serious effort. I have no trouble reaching 100C peak core temps on mine, despite relatively decent cooling solution.
It would be nice to reach maximum performance without liquid nitrogen cooling…
Tbh, I don’t know my goal yet. I’ve been listening up to 192/24 for a long time.
I mean, I’m not sure whether I can hear a big difference between DSD 256 and 512 settings, for example. But I want to try. That’s my plan. 
I only need stereo output, though.
And yes, I am planning to get a GPU as well.
4090 is quite expensive, and somehow, the price differs quite a bit among different models.
But this can be later, anyway.
Thank you for suggesting i9-14900K.
I had the 13900K on my parts candidate list, and I wasn’t sure whether I should go for Intel or search for some AMD CPUs.
I look forward to your latest CPU test results as well.
Thank you, as always.
13th Gen is getting a bit old, as is already 14th Gen too. But based on that I’d go with i9-14900K in a configuration that has enough space and PSU capacity to possibly later host Nvidia GPU.
You could later add for example RTX 4070 Super or 4070 Ti Super if you see need for such.
Another issue…
After updating the HQPe OS to 5.9.3 and the Holo Audio RED NAA to 5.1.2, I can’t connect to the RME inputs.

How do I fix this?
Network Audioid 5.1.2 is running on the Windows machine, and it detects the HQP machine, but seems to keep searching two IPs.
I’ve updated the runtime as well.
