  1. Hi All ER enthusiasts, I have a FiOS ONT, 30 feet coax to my Router, 30 feet Ghent catsnake JSSG 360, ER. One user was fortunate enough to have extra FiOS cable to move his ONT next to his set up and then a short connection to his router and a short connection to his ER. He reported a great improvement, but it was probably mostly because he was able to eliminate a fiber optic module. I cannot move my ONT but I can, with some effort, move my router next to my set up. The concern is that Wi-Fi also comes from the router. I have an extra 3 foot Ghent catsnake I could use from the router to the ER but I am worried that the wi-Fi would negate the benefit of the shorter connection. Does anyone have any experience with this? I could probably go into the router and turn off the Wi-Fi. Alternately I could run fiber optic The 30 feet from the router to the ER although, I would be sad to waste the 30 foot Ghent cable. It seems like it would be a good use for this fiber optic technology. My question is about power supplies. (I am using the stock power supply on the ER until I can get an appropriate LPS for it.) I recently put an LPS on the router and enjoyed the benefit it made. I had an issue with that LPS and had to remove it, I missed the benefit of it. If I add the optical module to supply the ER I am assuming The OR will benefit from a better power supply (experience please?) Does anyone have experience if they are using the OR does it still benefit to use an LPS for the router? Thank you
  2. I use Acourate Convolver digital room correction in conjunction with HQPe currently. It is my understanding that the best sound is currently from Euphony with Stylus player only. How would I use Acourate with this setup?
  3. Are you saying Stylus by itself sounds better than stylus with HQPlayer? What DAC do you have? Does it up sample? are you playing the Files at their native rate? I do not know if I can use an Optane drive in my computer and I’m not going to install a SSD or HD. I do not want to run off a USB drive forever. For long term I want to be sure that I can load the software into RAM and remove the thumb drive. I am excitedly looking forward to hearing from others that have a Holo Spring DAC. Please enjoy your day
  4. Hi, I am interested in trying Euphony/stylus. I am currently running AL with HQplayer embedded. I have Roon on my NAS. I do not have any hard drive/Optane my server/endpoint one box system. It used to be that Euphony required a hard drive/storage, but I understand now it can be loaded from a thumb drive into RAM. is this correct? Although, the trial has to be run off a thumb drive. It cannot be loaded into the computer? I have a Holo Spring DAC, it sounds best in NOS mode. Has anyone here been running a system like mine where they were using HQplayer to upsample to a Holo Spring DAC and they find Euphony with Stylus to sound better. With no oversampling? No HQPe. Can I use Euphony with HQPlayer embedded to upsample to Stylus player ? Have I read that some are using HPQe with no upsampling? Thank you Will
  5. Also, are you saying that changing the PSU of the server did not affect the sound quality of the endpoint?
  6. @bodiebill is the 400 W Seasonic currently feeding the 400W HDPlex DC – ATX? What is the amperage limit of the 12V rail or output feeding the CPU/EPS?
  7. Bodiebill- how much of that 33A goes to the CPU and how many watts is the CPU, please?
  8. This is interesting and counter to what Austinpop reported. That higher amperage sounded better, than a better quality and less amperage PSU, when powering the CPU. I wonder if he was powering the server or the endpoint? Or a one box system? I wonder if increasing the amperage to the CPU of the server makes an improvement when sending data over ethernet to the endpoint?
  9. @StreamFidelity your system must sound really good with the two Keces and the 800W HDPlex powering them. your system drawing is very clear and well done. I can see from the picture that you have both PSU set to 20V and combined they are using about 4A, so the total power consumption of your server is 80W. (I forget, is this build the server or the endpoint or both?) But, we do not know what the CPU by itself is using. It is interesting that your CPU is 95W and the entire system is only using 80 W. Were you playing music when you took this picture? So, this is a good reference point. It is also why I asked Austinpop what the power rating of his CPU is? Can anyone of us, who is powering the CPU separately, see what the actual consumption is? Or, is that not as important as knowing that you need a lot of power to keep up with the instantaneous demand of the CPU.
  10. My understanding is that Romaz has said powering CPU/EPS through the 800W HDPlex converter is better than powering it directly from the 12V of his 400W HDPlex, because the spec of the 800W is better (.1V variation). Not from any other separate 12V supply. A separate 12V supply should sound as good or better as long as the specifications are the same.
  11. How do you know that your max consumption is 19V /5A? Did you measure in line with both of the 8 pin CPU EPS at the same time, please? or is that for the entire computer? thank you
  12. How much power is recommended to power the CPU separately? And other system recommendations, please? I have a C.A.P.S. Pipeline server/endpoint, AudioLinux loaded into RAM, only running HQPe. No harddrive. I have Roon running on my NAS. The Pipeline is powered by a HDPlex 300W ATX LPS. I was one of the first to power every component of my computer with a LPS. (Ancient history alert: at that time I was waiting for the microRendu to be released and because of my impatience, my available funds went to the LPS upgrade.) I was using the power taps on the HDPlex to power my SOtM USB card and IsoRegen, the 19V tap was powering the NAS. Now I am only using the molex connectors out of the HDPlex to the motherboard, w/o the molex for the removed harddrive. Every time I removed a load from the HDPlex, the System sounded better and the PSU ran cooler. When I heard the good reviews of the HDP 400W ATX LPS I asked Larry if I could have my PSU upgraded because I wanted cleaner power. He said that the 300W is basically the same as the 400W. Now I hear good things about the HDPlex 800W DC-ATX. What if I use the 19V tap for the 800W DC-ATX. I asked Larry if I used only the 19V tap, would I get the full 300W. He said that I would only get 190W max, & suggested I keep using the system as I am currently. Once again I am back where I started. I have a 50W Zero-zone PSU that I am not using, so I thought it would be good to order an MPAudio HPULN for it, to clean up the power. I have not used the HPULN and do not have immediate use for it. (I now have an UpTone LPS 1.2 for every component that can be externally powered. My system is SOtM USB card > IsoRegen > Singxer SU-1 I2S. I thought with an LPS 1.2 on the IR & the SU-1 and USB card powered by the HDPlex LPS, that a third LPS 1.2 would not make a difference. I was wrong. Powering the TxUSBexp with a third LPS 1.2 was immediately much better) I thought that the HPULN had not shipped yet and a different way to solve the issue of getting better power into the Pipeline would be to have a separate PSU built for the CPU. I could use the almost $200 for the HPULN towards a PSU from MPAudio for the CPU. With Austinpop’s reports on the importance of a muscular PSU for the CPU, the question is what is the required amperage? What is the wattage of the CPU that Austinpop successfully powered 12v/7A? (I think) The Pipeline has a Xeon CPU that is 80W. 80W divided by 12V = 6.6A. But, this is the rated power and we have learned that heavily loaded the CPU will use more than its rated value. Is 10A enough? MPAudio says the 10A is 20 regulators, 22 for some extra headroom. Estimate 500 euro. How would this PSU design compare to the other popular PSUs? Would it be worth the extra $30 to ship the now in-transit HPULN back to use the credit? Now is where it gets crazy and I beg for a reality check. (sorry for the long post) I want to make sure that a dedicated PSU for a CPU will stay viable over the long term. I am only running a one-box system because I am waiting for the dust to settle and an endpoint that will emerge that checks all of my boxes. I missed on the microRendu and things kept getting better with the off the shelf NUC. I fear that the day I order a NUC or iBox-V1000, the SOtM motherboard will come out or something from one of our other heros. Also, I am not in a hurry because my system with the EtherRegen already sounds magical! So, I do not mind waiting. But, while I wait I might as well make my existing system sound as good as I can. Upgrading the PSU for the CPU will do that, as long as I can reuse it later. I use HQPlayer which has the new EC modulators would need a 5.0 GHz CPU to run DSD512, which currently does not exist. My Pipeline can run the EC modulator at DSD128, but the CPU is working so hard that it sounds like crap. I run PCM at PCM384 and it sounds great. The next Xeon CPU that Miska is looking at does 4.7 GHz turbo and is 155W. To future-proof for a dedicated CPU PSU with that load would be crazy. I could possibly move the new CPU PSU over to the future endpoint, but it will probably take 19V and what are the odds that it will have a separate input to power the CPU. Also, the endpoint PSU should be the “best you can get”, which probably means double regulated and I am not going to build a double regulated CPU PSU for the server. I have the EtherRegen but have never sent ethernet to an endpoint, how important will the PSU for the CPU be then? This is why I am reaching out to my friends here for advice, please. What would you do. What should I do. Thank you
  13. In the write up by Romaz, he says the SMG Extreme uses a ASUS server motherboard. Can anyone report on exactly which motherboard?
  14. Thank you. what is happening with the orange profile compared to the green or red profiles? is it setting the CPU to a specific clock speed or percentage of clock speed? Does it allow it to work with turbo or something like that?
  15. Hello Friends, I am trying to understand the profiles menu and whether I should use the orange (default) or auto. The AL webpage says to go to the release notes for more information, but I do not understand the “examples” there and how they correspond to the different choices. I am using a CAPS Pipeline computer without a NUC or NAA. I am only running HQPlayer embedded on this computer. (I am not converting PCM to DSD, so the CPU is running comfortably). (because of this I did not think it is necessary to isolate cores). I have Roon installed on my NAS. I use RAMroot, of course. The only setting I do is to enable ACPI scaling. I have enabled turbo boost, but I believe this only allows HQPE to do it’s thing when it needs the extra power? Because of the above I have enabled the “auto” profile. My assumption is that this will allow AL to optimize my settings. Is this correct? Will people please report their adventures with these profiles? also will you please make recommendations for further optimizations I can enable? Thank you Bill
