  1. This was a really interesting read. In particular, I was struck by the description that HPET forced on in the OS for intel based systems increased latency but reduced errors. Is it wrong for me to extrapolate that, in the context of audio processing, that forcing HPET on in the OS would result in higher latency but less variation in latency given fewer errors? This seems to be true for both AMD and Intel (see below). If so, this would correlate with @ray-dude's findings that he presented in part two of his SGM Extreme review. Lastly, if true, this reasoning would indicate you would want HPET on. @lmitche, what am i missing here? I have an old AMD system running AL. I'll mess around tonight with my settings and see if I can spot any differences.
  2. @ray-dude, these write-ups are making my week. Question for you - do you see any off-the-shelf regulators in use in the power supply? I know Taiko has previously used Belleson regulators, but this power supply, ostensibly, looks like a standard CLC / Pi-Filter with substantial emphasis on the C's. As such, it seems like Emile could be letting the motherboard handle all regulation from a power source with VERY small, sinusoidal, low-frequency, ripple? Or is Emile using a discrete regulator instead of a monolothic regulator following the pi-filter?
  3. Sounds good - i'll try re-scanning in different clients. Thanks!
  4. Correct. I'm using maximum MPD, clicked update databaser, and i have 0 items. There are three folders, none of which are the /Media/Music1 mounted music folder i created
  5. Real basic question for you all. I've mounted my music folder, downloaded an MPD client, and enabled MPD. However, I cannot see my music in the MPD client when i connect to the MPD server... How do I get my music folder loaded up?? Thanks!
  6. Sorry, maybe I'm amazon illterate - how much does this battery cost??? It is not available.
  7. 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.
  8. 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.
  9. @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
  10. 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.
  11. 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.
  12. @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?
  13. 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!
  14. 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?
