  1. Assuming I pulled the right diagram (see attached), it looks like the USB ports on the SGM extreme motherboard Emile uses also pulls from the chipset and is not cpu direct.
  2. Here's what I know regarding storage... Extreme has low-latency storage in the form of PCI-E mounted NVMe. That specific ASUS board in extreme from Asus Emile uses supports Intel vROC... The biggest advantage of Intel® VROC is the ability to directly connect NVMe-based SSDs to the new Intel® Xeon® Scalable processor PCIe* lanes, then make RAID arrays using those SSDs without using a RAID host bus adapter (HBA). As a result, Intel® VROC unleashes NVMe SSD performance potential without the complexity and power of a traditional hardware RAID HBA. In this way, Intel® VROC was designed specifically for NVMe SSDs, and is positioned to appropriately support this technology and help transition the market to these faster drives.I personally am disappointed that it takes 24k euro to get the most out of roon. Don't know vroc is enabled or not but the above is what I've read.
  3. @Nenon and @Dev, FWIW, I've read that Taiko uses Belleson regulators in other products and Emile says he learned a lot about power supplies from that experience with respect to building his servers. Belleson has a 10A regulator you can use (link below). Many other audio manufacturers use a CLC / Pi filter with the Belleson to take the high frequency edge off. I also believe Emile mentioned he used inductors in his power supplies, so I wouldn't be surprised if he also uses a CLC prior to the regulator. https://www.belleson.com/store/SPHP-High-Power
  4. Just a point of clarification - I asked Roy why he doesn't use a regular CPU case with a passive heatsink. One can achieve the same, well-known benefits you describe above, @shahed99, including 120W TDP compatibility, and use a full ATX motherboard. As you know, passive heatsinks do not have any fans / moving parts / noisy motors. I bring this up because Roy was lamenting using uATX boards simply for case and cooling compatibility.
  5. Thanks @romaz for another kick ass post! If you have the time, I'd love to get your perspectives on the below questions: Have you tried tweaking the RAM refresh settings per Emile's discussion on the SGM "Creme de la Creme" thread @ whatsbestforum.com? If not, why? I figure that kind of adventure is something you'd like to try! And truthfully, I would have bet that would have been your first question to Emile knowing only what I know about you from this forum (i.e., you are a hyper-sophisticated listener and system builder that has spent significant and precious time and treasure tweaking your system. Plus, modifying refresh cycles is a novel idea!). His comment on that thread of "shaping the EMI / RFI" via RAM refresh settings really struck a chord with me (pun completely intended). I'd love to get any thoughts you have on this. Did the below quote make sense to you? Because it didn't to me... If you reduce your active processing times, baseline power consumption goes up (makes sense - you feed the CPU and RAM more power to do work faster)... Yet power draw does not vary much? Wouldn't power draw go up and then down? Just wondering if you could unpack this for me! What am I getting wrong / missing? Have your perspectives on storage changed? In particular, have you tried loading the OS and Music on boards similar to the ASUS Hyper M.2 x16 3.0x4 board(s) Emile uses? I know NVME storage has been discussed at length here, but a solution that allows one to get the bandwidth and low latency of a PCIe x16 lane and the storage capacity of a very large HD seems new (unless I missed something, which given the massive length of this thread is not unlikely). Apart from aesthetics, is there any downside in using a regular ATX case with passive heatsinks, as opposed to heatsinks that are built into the chassis? Something like this, for example, could, in theory, cool a higher TDP processor (especially if underclocked / "tuned" to a certain frequency) while allowing you to build in an ATX form factor. It doesn't look as cool as a Streacom case, but it would get the job done. Why limit yourself to a smaller form factor if you don't have to? As a comment, I think Emile's explanation for why 2 DIMMs may sound worse than 1 DIMM is extremely elegant and strikes me as intuitively sensible. Very very cool progress in understanding in this thread. Awesome stuff. I really love this thread.
  6. @austinpop Two questions for you: Why is the Cavalli amp not also plugged into your PS Audio Regenerator? Do you find the Dave's headphone amplifier insufficient for your sets of headphones? Or is the Cavalli adding something that the Dave's headphone amplifier can't provide?
  7. Great review, Rajiv. Actually reading this at the Odd Duck on S. Lamar. I dig your city! I will admit that the thought of a DAC that can't be improved with upstream tweaks scares me a bit... I guess I'd have to learn how to build speakers!
  8. Hi @austinpop, thanks for the update! Did I miss something? I hadn't realized you went back to the Roon server + SoTM solution from the Euphony + Stylus one-box solution. Any update here? Or have I just gotten lost in the morass that is this and the other threads?
  9. I find the type of DAC used determines whether upsampling is beneficial as well. For instance, my Chord 2qute sounds much better with native PCM than upsampled PCM or DSD.
  10. Actually many folks here rely far more on their ears than measurements. You'll notice no measurements have been provided supporting many of the claims made on this forum. What counts is whether or not, once you test a claim, you agree or disagree with the OP (e.g., @romaz, @austinpop, or @lmitche). That being said, I've definitely purchased what I thought was an amazing piece of equipment only to realize music quality decreased once I added it to the chain.
  11. How do you deal with enclosures and making holes for the IEC connectors and barrel plug / XLR outputs on the PS??
  12. Ramroot is really the value-add step IMO. It is very easy to set up - I have complete confidence you'll get it up and running in no time, especially since you've gotten this far! Good luck.
  13. Thanks for the review! Does Adrian have detailed specs on the power supply? Is the regulation discrete or does he use LDOs?
  14. A random and very innocent follow up question... Would the same be true with a JS-2?
