Popular Post Nenon Posted January 18, 2020 Author Popular Post Share Posted January 18, 2020 I decided to keep the ASUS Z390-I ROG Strix mini ITX motherboard. The ASUS ROG Maximus XI GENE looks really good, but I have some concerns about using it in this build. First, looking closer under different angles, I don’t think the ultraOCXO would fit. This is where the OCXO would end up approximately. It. The metal heatsink would be on the way. I was thinking to take the PinkFaun card to my local MicroCenter store and ask them to check if it would fit in the ASUS ROG Maximus XI Hero (since they don't carry the GENE), but I don't think it's worth the effort. It seems quite obvious that it would not fit. Second, I am worried how close the JCAT NIC and PinkFaun USB would be to each other. Both of these cards are very important. @RickyV had an interesting shielded solution, but it's a moot point if the PinkFaun card does not fit. And third, the smaller motherboard has less components (potentially less EMI), shorter PCB traces, etc. There is plenty of space for the regulators now. The overall layout, heat management, and EMI management matters. Also, the PinkFaun is connected to a 'premium' and shielded PCIe slot now. It would have to be connected to a regular / unshielded slot on the Maximus (not sure if that matters at all but it's another variable to consider). Yes, the impressive VRM on the Maximus might be more important than any of the factors I have listed, but since the PinkFaun card would not fit, it is not even an option to consider anymore. Otherwise, I was tempted to try it and compare. This music server sounds so good the way it is! I don't think any more changes are necessary. It is time for the new owner to start enjoying it. This is the best USB source I have heard, and it's still breaking in and opening up... I can hear it. I have not heard many, but I've played around with high-end digital sources for a while. Can't compare it with mine, because mine was I2S based. At this level of quality, the interaction with the DAC is much more noticeable than the small differences of the servers. Also, I decided to keep the ECC RAM. That means I would have 2 x Apacer Non-ECC 4GB modules available. If anyone needs them, ping me on PM. motberg, StreamFidelity, RickyV and 1 other 2 2 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment
Popular Post Nenon Posted January 18, 2020 Author Popular Post Share Posted January 18, 2020 Final touches. The EMI sheet I used is from 3M (part #AB5100SHF) https://www.mouser.com/ProductDetail/?qs=gMfM3zrbS4r0qTugzC4tdw%3D%3D You have to be careful with that stuff. If you put too much it has a negative impact. Not a lot to treat on this motherboard. I put a piece on the big heatsink and a little piece on the OCXO clock. That should be more than enough. I would keep it at that. There is no right or wrong way to do this. Sometimes I add a small piece to the memory, but that can easily fall down. Also, I typically add some very tiny pieces on some of the chips on the motherboard, USB and Ethernet ports, but I don't feel the need for that with this motherboard. I treated all connectors with the Walker Audio silver paste. That includes the ATX connector, that EPS connector, and all the external GX16 connectors. I used Walker Audio Quantum Silver Contact Treatment with Nanocrystal Technology paste. Here is a link. Not sure how visible that is on the pictures. I also applied this damping material on the covers. It's a car sound dampening mat from a company called Noico Solutions. The model is ESN10. And the last thing - adding a SR Orange fuse. That's my favorite fuse at the moment. I went back to the BIOS and did a few other small tweaks. The very last thing I am tweaking now is the process affinities / CPU isolation in Euphony. And that concludes this DIY music server build.

Popular Post Nenon Posted January 20, 2020 Author Popular Post Share Posted January 20, 2020 Played quite a bit with CPU Isolation today, and so far, for this build the following sounds best in my system: 0-1 stylus 2-3 gstp 4-15 That would also need tweaking for Roon later, but with Stylus I can hear more of the room ambience and the music gets even more engaging with these settings.

Something new for me, all I’ve been doing is 0-1, stylus 2-3, 4-7 hqplayer? thanks in advance gstp handles pretty much all the audio processes in my case (no Roon, no hqplayer, just Stylus player). stylus handles the web interface functions. I did not find isolating stylus to have an advantage on sound quality, but I did find isolating gstp to have a significant benefit. It's a little confusing, because one may think that using the Stylus player may mean that you need to isolate the stylus process. But the actual audio-related functions are performed by the gstp process. Obviously, since you use hqplayer, that's probably the most important process to isolate and assign more cores to. You may have a slight benefit by assigning 2-3 to gstp rather than stylus. Try something like this: 0-1 gstp 2-3 hqplayer 4-7 LJONESATL 1 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment

I have a notepad with possible codes but didn’t mark the code in use. So I put in the code I thought it was but while listening something was off. It sounded muddy, not accurate (0 gstp 1-2 stylus 3),most cores to gstp . I remembered the temperature pattern the cores give so it was not to difficult to get the original code back and liked it much better, 0 gstp 1 stylus 2-3. So giving the most cores to stylus. Maybe it is all different when you have 6 or 8 cores to play with I do not know. But if you have the bare minimum cores for the core isolation function to play with I prefer giving the most cores to stylus. I guess the results vary in different systems. As I have mentioned earlier, stylus is doing the web ui processing, not the audio-related functions. gstp is doing all the caching and playing. But maybe stylus needs at least a couple of cores for better load distribution. Have you tried "0 stylus 1 gstp 2-3" instead? Just curious of splitting gstp between cores 1-2 sounds worse than keeping it on 2-3.

Nenon Posted January 21, 2020 Author Share Posted January 21, 2020 Perhaps that's the winning formula for a quad core CPU then. 0 gstp 1 stylus 2-3 I would have to think hard to understand that one. BTW, have you tried 0-1 gstp 2-3? That would give stylus two cores shared with the rest but would isolate gstp. It would be interesting to report on that one. In my system it is really easy to hear the benefits of isolating and assigning more cores to gstp. But that only proves again that what works best in my system does not work best in others.

Nenon Posted January 22, 2020 Author Share Posted January 22, 2020 I also settled on 0-3 stylus 4-5 gstp 6-15 for now. That might be a good formula for an 8 core / 16 threads CPUs. Also, the server shipped to its owner. Both chassis combined together were 45 pounds. I am now impatiently awaiting feedback from the owner :). That is the most important thing after all!

Do it benefit from it or is that only to pass power to the DAC? I can't tell from their website. I think it requires external power. But even if it didn't, I would always use external power supply. This is one of the most critical places for a good quality power supply. It's also very sensitive on DC cables and everything else.

Hope he/she is loving the musical fruits of your labor. Any idea what they had before and how it compares? Not yet. It takes some time for the server to burn-in. All those silver wires in teflon, big Mundorf caps, OCXO clock, and big toroidal all take quite some time. Also, one component failed after working fine for a week, so we are now dealing with that. From my experience it takes about 3 months for these servers to start playing optimally. They sound pretty good from day one but go through a long burn-in process, and during that process the sound quality could be inconsistent. Hopefully when the server is all settled, the owner would post his impressions. He had a highly tweaked two boxes (server/streamer) solution, so it would be an interesting comparison. beautiful music, LJONESATL and Chopin75 2 1 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment
Popular Post Nenon Posted February 5, 2020 Author Popular Post Share Posted February 5, 2020 3 hours ago, dctom said: Very interesting thread, with great information, thank you. I had embarked on my own build about a month ago, unfortunately only discovered this topic a week or so ago. I am using the ASRock Z390 ITX/ac I see you were using at the beginning before swapping it for your preferred better sounding Asus Z390. However the ASRock is performing very well with an i79700T in the new HDplex H5 case. Powerful processing and low power consumption - I have posted some details and photos on the; Design a PC/Server for ROON and HQplayer thread. I have used the AsRock in previous builds. It's a great motherboard. You can't go wrong with either of them. I have a slight preference towards the Asus. Also, speaking of HDplex H5 and Asus ROG motherboards, I have the big brother - Asus ROG Crosshair VII Hero placed in a H5 case (not mounted, just placed on top). This is obviously an AMD motherboard, not Intel. When I did the build in this thread, I had a lengthy discussion with the now owner of this server, and it was decided to go with what I already knew works best rather than experimenting with new things. The Asus motherboard was a wonderful serendipity. So, time for new experiments with a bigger Asus motherboard now. The three BIG questions I would like answers for are: 1. Does this big full size ATX motherboard sound better than its smaller sibling I am currently using in their stock versions? 2. How much better Qobuz would sound (if it sounds better) when my JCAT NET Femto NIC is on a regular PCIe slot with no extension cables? 3. Last, but not least, what would be the effects of changing the motherboard clocks with high quality OCXO clocks? That's the part I am most curious about as it's something I have never done before. If time allows, I may even document the clock changing process here, but I am not promising. What I like about the H5 case is that it supports a full size ATX motherboard and allows you to mount all PCIe cards vertically with no adaptors. What I don't like about the case is that this plate needs to come out completely every time you want to add or remove a PCIe card. But I haven't assembled it yet, so maybe there is a workaround this. It also feels a little cheaper quality than the Streacom, and I wish the top and bottom plates were thicker. This won't be a fully documented build like I did before, but rather some comparisons after I do the work. It would probably take several weeks before I have any discoveries I can share. I may post some info on the clock changing process, though. The first problem I am running into - I am not sure which PCIe slot is connected directly to the CPU and which goes through the chipset. If anyone knows, please let me know. It would save me some time. Ultimately, if I can't find any info I can probably trace the PCB traces on the motherboard and figure it out, but that would be too geeky :). Stay tuned for more updates. auricgoldfinger, beautiful music, lwr and 9 others 6 4 2 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment

One can buy a Statement instead, but there are a few things I don’t like about the Statement - the low powered CPU does not sound as good as this configuration; the SSD drives are too noisy, and I don’t want to have any in my servers; Apacer RAM is a must; the wiring (silver/gold wires used for everything) cost $1,500 alone… if the Statement had the same wires and cables, it would probably cost $5K more just for that… that’s not including the amount of time, it takes to do all the JSSG360 shielding and every small detail. And those cables make a big difference. I’ve heard the Statement in a few occasions and liked what I heard. But I’ve never had one in my system to compare with a DIY server like this. It's hard to do such comparisons without having both servers running side by side. But I think we have went quite a long way in the DIY computer world. I don't think we can compete with Taiko Extreme, which is at a completely different engineering level than anything we've done here.

Nenon Posted February 6, 2020 Author Share Posted February 6, 2020 23 minutes ago, rickca said: According to the manual, the first two slots are connected directly to the CPU if you are using a Ryzen 2nd gen processor. The 3rd slot (which is PCIe 2.0) comes from the X470 chipset. The two PCIe 2.0 x1 slots also come from the X470 chipset. The first two slots are designated PCIEX16/X8_1 and PCIEX8/X4_2. These are the ones connected directly to the CPU. Note also the PCIEX8/X4_2 slot shares bandwidth with the M.2_2 slot and will run in x4 mode if M.2_2 is enabled in PCIe mode. Thank you. That makes sense, because these are also the two steel enforced PCIe slots. In that case, the plan is: - PinkFaun Bridge in PCIEX16/X8_1 - JCAT Net Femto in PCIEX8/X4_2 - Optane in M.2_1. - Leave M.2_2 unused. Actually I need to check how M.2_1 connects. Hopefully not through the chipset. I may end up using M.2_2 instead.

For some reason, squeezing the last bits of sound quality performance is not and has not been Roon's top priority. They have their own agenda and don't like to listen to audiophiles (which is probably most of their customers). For example, we have been asking Roon for years to buffer the track in memory before playing. And they kept ignoring those requests. I've had a few interactions with Roon, and I gave up. They like to operate in a closed/secretive manner and don't even want to share their roadmap. I have a lifetime subscription but don't use Roon. You will find that most of the people here use Euphony, AudioLinux, or a highly optimized Windows OS. Our findings are that Roon sounds better running on those operating systems. I use Euphony. And if you can sacrifice the Roon interface for something that sounds better, the Stylus player in Euphony is your best friend. Also, you can easily switch between Roon and Stylus. I still find Roon great for discovering new music and don't mind switching to it and enabling Roon Radio for background listening, so I can discover some new music. Also, unlike Roon, I've had multiple interactions with the developers of Euphony and AudioLinux, and all my concerns were addressed, and everything I have asked for eventually popped up in one of the new releases. beautiful music 1 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment

Roon sounds different on different operating systems. If you are curious, you should experiment. Euphony gives you a 30-day trial. And that trial, at least for now, is per computer, not once in a lifetime. This way you can try it on different computers. Some people can't hear a difference, most likely because they don't have very resolving systems. Other people can hear a huge difference. AudioLinux for example is a tweaker's paradise. There are so many different things you can try to dial-in your streamer. You just need a lot of patience and time for tests. I have about 20 years of experience managing Linux servers, but I wanted something with less options, so I can enjoy the music rather than constantly dialing in my OS. Euphony is a closed Linux-based operating system, based on a similar OS like AudioLinux. It sounded right for me from the first time I tried it. It's closed, because you don't get root access to the operating system and can only change the settings that are provided to you in the web interface. There are two modes for Roon - Roon Core and Roon Core + Stylus EP. And Roon does not sound the same in both. One of the options that both Euphony and AudioLinux provide to you is CPU Isolation. I can isolate processes to their own cores. It's an interesting test, because I can change that in real time while the music is playing and clearly hear a difference. There is a discussion about that earlier in this thread where we tried to narrow down if there are universal CPU Isolation settings that work for everyone. It turned out there isn't. I guess it's system and personal preference dependent I won't answer what is "better", because what sounds better for me might be worse for you. But I hope the above gives you some perspective, and you can experiment on your own. lwr, ciccio1112, beautiful music and 1 other 1 1 2 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment

Compared to a Streacom F9, the Hdplex was much more flexible enabling use of all the pcie slots of a MicroAtx motherboard in a smaller case than the H5. While I understand that one could consider the aluminum materials used in Streacom to be of higher quality, the Hdplex uses a mix of steel and aluminum in a practical, highly evolved design. Hdplex cases will be my first choice going forward. Better overall design with what seems like cheaper materials. I like how the passive cooling is done. More copper pipes with rounded grooves in the heatsink for more contact surface. Pretty nice. I haven't done a comparison between the heat dissipation on the Streacom FC9 and the HdPlex H5, but my money would be on the H5. I also like that the HdPlex is the first passive cooling chassis that gives you the option to use all PCIe slots without extenders. It makes me wonder what the hell those manufacturers have been thinking all these years! As for the removing plate - I am glad you like it, but I find that part of the design the worst thing about this chassis. In order to add or remove a single PCIe card, you have to detach all of them from the plate, and you have to remove the entire plate. This is horrible, especially when you have a bunch of power connectors installed on that plate with nicely routed short thick wires like I do in my builds. I guess I will have to make those wires longer now (increased output impedance) to make it possible to add / remove PCIe cards. I would not call that genius design.

It is running well and is keeping the i79700T at around 35 deg C. I am using audiolinux with HQplayer 4 with poly-sinc-ext2 and ASDM7EC, 2x dsd. Very pleased so far. It is running as a server for my i7 NUC client. This has provided a superior SQ to using the ASrock as an all in one. Glad you like it. Your CPU is somewhat easier to cool compared to some of the higher power CPUs. Nonetheless, I have no doubts in the cooling capabilities of the H5. That's why I bought one too. Also, I am not surprised that you liked the server/streamer solution better. There are some special considerations for making a single box sound better - powerful CPU, very clean power with a lot of headroom (especially for the CPU), PCIe card for the digital output externally powered by a good LPS, and many other small details, that can be seen in my build. Plus, I don't upsample with HqPlayer, so that could make a big difference too. I have 8 CPU cores / 16 threads on my server. You can rarely see any of them exceeding 1% CPU utilization and the frequency quite often goes over 4 Ghz and rarely under 3.5 Ghz (without explicitly configuring any CPU frequency settings). This is when the magic happens.

Nenon Posted February 12, 2020 Author Share Posted February 12, 2020 Just a small OCXO teaser. Also, please note the paper sticker on the motherboard that says 1201. This is the BIOS version. And this is the fourth AMD motherboard I get that is running an old BIOS, which does not work with the AMD Ryzen 7 3700X CPU. With such BIOS the server would not post. With the previous mini-ITX AMD motherboards, I had to go back to the store, buy an old CPU like the AMD Ryzen 3 2200G and install it just so the server can start and I can update the BIOS. This motherboard has BIOS flashback function. You can update the BIOS from a USB drive without CPU or memory installed. So much easier! motberg 1 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment
