The new Joni Mitchell box has arrived and I'm really enjoying this one in Atmos.

If only you could add some offload on Intel ARC / Iris Xe graphics, please! That will be so much appreciated by us, the NUC users! 🙏🙏🙏

Thanks for sharing. My speakers are NHT C3, 84db, so very hungry and not efficient at all. Impedance curve around 6 ohm. With the Apollon NCx500 Stereo, with only one, shared, power supply. I am not running out of power, but I believe separation indeed.

R128?

Odd, then, that Roon reports a 7 for dynamic range of the Atmos version. JCR

Yes, no problem. And I know that when using these niche cutting edge things, there are sometimes rough edges in the beginning :) Thanks again for your support both @Zaphod Beeblebrox and @Miska.

Yes, it was supposed to do nothing! except someone reported the issue to me yesterday and I found that there was a bug. Obviously, I had no idea you were using silence/trim/add. I created the silence/trim section for a long term PGGB user who made a special request to do so, I did not know of anyone else even using it! With high-rate DSD, not many players/DACs/Drivers handle them correctly, which is why I mentioned too many variables. But in your case, I am glad it was something much simpler.

Try this on console: cd /tmp wget https://www.audio-linux.com/ftp/temp/hqplayer-embedded-5.5.3-1-x86_64.pkg.tar.zst sudo pacman -U hqplayer-embedded*

While waiting to receive the new SD Card, I veered left and installed Audirvana Studio. Wow, this sounds good! Real good. Try it, you get a full product for a full month no cost, no risk test!

Beyond the bone conduction information you cited with regard to frequency, there is also the matter of perception of timing. The majority of experiments find we can perceive timing differences as brief as 10 microseconds, which would correspond to a frequency of 100kHz. (Kunchur’s paper gave a result of 4 microseconds, but since this is controversial with many people, let’s stay with the majority.)

I used Audirvana a long time ago and then switched to Roon for the past 5 years or so. I decided to give Studio a try this week. First, I like the pricing. It's about 1/2 the cost of Roon. And you can do a full month with a full product for Free. So, trying it is totally risk free. Then if you want to subscribe you can go monthly, cancel any time, or pay a reduced cost for a full year. NICE! Setup was initially confusing - but not difficult. I'd say the learning curve is less than one day of using the software. I use a SoTM SMS200 Ultra Neo network streamer and I couldn't easily find instructions for this. But with more dedicated looking I found enough info to make is work easily. It sounds great. Does it sound better than Roon or Roon with HQ Player? I kind of think so, but I haven't used it long enough to be sure. I like to use a product for a week or so before going back to the other product I'm comparing with. There are some features in Roon that I'm missing in Studio - but It could be just my inexperience with the GUI. If you haven't given Audirvana Studio a test I think you owe it to yourself to give it a one month Free trial.

I split my test track into 10 seconds in Audacity and then tried upsampling with different settings. Indeed, trimming and adding silence was the problem. Guidance mentioned that it's for PCM only and I assumed that then it just does nothing, but it actually creates problems. When I turned off trimming and adding silence, everything works perfectly. Good that I hadn't processed more albums :) I'd suggest to put some kind of a warning in the Guide that it's not only not supported for DSD, but leaving those settings on will cause problems. I spent a lot of time looking at HQP NAA bios settings, testing different cables, galvanic isolation etc etc. It would be nice if no-one else would need to go through the same process.

Thank you for the excellent report. I nominate it for post of the year.

Trim silence applies to the source, if your source is PCM, it will trim silence. If your source is DSD, it will not do anything. But add silence, as it is implemented now, it will add PCM silence (i.e. add zeros) at the start and end of the DSD track. For DSD output, this will exacerbate the problem (when combined with also trimming PCM silence). This is a bug that will be fixed. For the purpose of your tests, please do not use the trim/add silence.

Brings bad memories, thanks!

It says the "Mistery of Music I Mysticism" A Indian Yogi and professor talks how fundemantal music is, much more than the word. A universal truth... From the description Hazrat Inayat Khan (1882 –1927) was an Indian professor of musicology, singer, exponent of the saraswati vina, poet, philosopher, and pioneer of the transmission of Sufism to the West. He initially came to the West as a representative of several traditions of classical Indian music, and established an order of Sufism (the Sufi Order) in London in 1914. By the time of his death in 1927, centers had been established throughout Europe and North America, and multiple volumes of his teachings had been published. Inayat Khan's teaching emphasized the oneness of God (tawhid) and the underlying harmony of the revelations communicated by the prophets of all the world's great religions. His discourses treated such varied subjects as religion, art, music, ethics, philosophy, psychology, and health and healing.

In all fairness, until now we've only been able to hear Audirvana running on Windows or macOS. It may run more efficiently and sound better on Linux.

Yes, but the filters also react how the DAC works, doesnt it? ok, when we accept to hear more than 20kHz, then of course it makes a difference. I guess the science is not settled ;-) Last, the article brings up the question if a audio chain can reproduce ultrasonics correctly or if it adds other artifacts in the analogue stages. And if we rather concentrate our efforts on the actual audio band or not. And no, I cant answer these questions. But thanks @Miska for your thoughts

I have not run into any pop issues, truly gapless albums (like Opera) transition smoothly without gaps or pops. There are too many variables here, so please DM me couple of problematic tracks (originals not converted) so I can look into it. What I would also like to know is how the same tracks behave at DSD512. Regarding silence, you are correct, PGGB does not currently support adding silence to DSD. However, I am planning to add that option.

Hi, I use 6.7.5-x86_64-GentooPlayer-ST-RT-SKYLAKE-CLTO kernel from Gentooplayer and it works well!!

Actually after further debugging, there is some truth in that these tracks have pop issues. It happens on some tracks, but not on others. I can reproduce the same results. It also doesn't have anything to do with rate family. I have content both in x44.1 and x48 families both with pops and without pops. To me it seems like it has something to do with silence in the beginning of the track. Those that don't pop, don't start immediately. I have processed these tracks with a setting that trims track and adds silence in the beginning of the track, but it I seems that it only applies to PCM. Also not sure if that would fix the issue anyway, this is just my educated guess. Is there some technical reason for why that silence can't be trimmed/added for DSD @Zaphod Beeblebrox? And on the other hand I miscommunicated earlier that I wouldn't get these pops in playlist mode. I at some point thought that these pops wouldn't occurr in playlist mode, but it seems to happen everywhere. Also: this problem seems to occurr even if I pause the track, move in the beginning and continue. The beginning of the track is somehow corrupted or something. I get pop, one second of silent hiss (or silence, not sure), another pop and then music starts. Otherwise I can pause, start and move within track as much as I like. It's just the beginning. I also found one track that is just 1:45 min long that I can use for debugging. I will try upsampling with different settings and see if I can find the root cause.

Thanks much for sharing detailed comparison/ inputs; definitely helps! Yes, Roon does provide its own set of benefits from a user experience / DSP perspective. I was with Roon on a Lumin before moving to Aurender Am also trying to understand if a move from w20 to N20 ( with additional expense) would be an upgrade/ downgrade/ pretty much equal purely from a SQ view point. Any inputs are appreciated.

Yes. BCV is dual rate

I'm sure it will do fine. One thing to verify when using any variant of linux is what kernel version is needed for your new HW to work and whether the player OS you are using is at that version or better. When using Euphony the developers kernel version lagged so that for a while I couldn't use the onboard Ethernet NIC of an i11 NUC.
