  1. Romaz has mentioned in his last post that powering the CPU/EPS through HDPlex 800W DC-ATX sounds better than directly powering by a 12V rail.
  2. That could be a very effective solution esp for someone who doesn't want/need a streacom/hdplex type passive and make it work with regular chassis. But might need to make sure to not stress the system/CPU and have adequate ventilation and ambient temperature if powering a CPU with TDP of 95W or greater. It's been a while since I watched this youtube video to remember the details where the reviewer tried to power a Ryzen 3900X with CR-95C. As far as I recall, it was useable but the temp was quite a bit on the higher side even when the system wasn't on for that long.
  3. There are no proven, ready to purchase passive heatsink available in the market capable of cooling TDP > 100W CPU effectively, at least I'm not aware of any. The Noctual one you've linked, I've been keeping an eye on them for a while. So far, it's just a concept with no indication when or if at all if will be released. I vaguely recall another concept passive heatsink that were suppose to be capable of cooing ~100W CPU but the manufacturer had to abandon the idea for whatever reason.
  4. I got excited when I first saw this case. However, this is not meant to be a passive case. Problem with using after market passive cooler like NOFAN is that either you'd need to install an intake and exhaust chassis fan to dissipate the heat off the passive cooler as there's no heat pipe that is touching the chassis surface to dissipate the heat to outside environment or you need to have the chassis open to have free airflow from outside. But I suspect, in either cases you'd not get TDP 80W of cooling with CR-80EH, more like 65W that precludes the best in class CPU that starts with TDP 95W.
  5. There are primarily two reasons for using passive cooling: i) noise and ii) resonance/vibration induced by moving parts. These days there are silent fans (Magnetic Levitation Cooling Fan) available that are practically inaudible. However, the fact still remains that those are moving parts that causes vibration/resonance on the motherboard, which is not good for sound. The only solution to keep using a passive case (HDPLEX/Streacom) is to use a CPU with TDP 65W. However, as reported by both @romaz and @austinpop, beefy CPU with high core counts, large L3 cache and higher frequency sounds beefier and dynamic. But those often has greater than 95W TDP. The challenge is how to passively cool a CPU that has TDP >= 95W. @seeteeyou has posted some links about upcoming passive chassis that might be capable of supporting TDP 250W looks promising. But one solution that I see that is rarely mentioned is water cooling. I recently built a music server using Ryzen 3950X (16C/32T/64MB L3) with TDP 105W. 7nm CPU are more power efficient but generates slightly more heat than 14nm chip. My Streacom FC10 (even with extended heat pipes and kryonaut paste) wasn't enough to cool the beast. Hence, I used a Corsair AIO cooler, which breaks no sweat keeping the CPU temperature under 35C even when running my server nonstop for days. The radiator fans are placed outside of the chassis to reduce vibration and I can't hear them at all sitting 7' away from my speaker. However, given this is a AIO - there's a pump sitting on top of the CPU to move the water through the pipe. It's not audible but still is a moving part. So, not ideal. However, if you can spend money $350-$700, there are custom water cooling solution where radiator/fans/pump everything is external to the chassis and with long tubes those can be further away from your listening position and inaudible. There are no CPU on earth that can't be adequately cooled with custom water cooler solution with no moving parts inside the chassis. Even without any mobo clock upgrade like my previous build of i7-4770T and linear ATX PSU, this new server with off the shelf switching PSU sounds like a component upgrade over the old ones. It's massively dynamic sounding. While the sound has some high frequency harshness due to using switching PSU, I suspect it'd be gone when I get a linear PSU.
  6. I was able to purchase a Ryzen 3950x today. I'll build my music server over this week/end. I'll post an update how it handles HQP upsample.
  7. Better than your custom built Xeon?? The value is off the charts! I just bought a Ryzen 3950X. For me, HQPlayer is a must. If that wasn't the case, I might have considered returning it in favor of UsbBridge-Sig. Great review!
  8. @Nenon Thank you for facilitating purchase of Apacer RAM. I am eagerly waiting for mine. I became a RAM believer when I build my dedicated music server using all Paul Pang components in early 2015. I recall when I was waiting for Paul Pangs special RAM (non ECC) to arrive, I was using regular consumer grade RAM. Once I replaced them with PPA RAM, the improvement in sound quality was immediate, noticeable and quite significant. I still have those although they are DDR3 RAM. I'm curious what Paul Pang has up its sleeve lately.
  9. This! Couldn't agree more. Our system, ears and personal preferences are obviously different. So there's no absolute in this. I'll be brief. For years, I've been using Windows Server optimized with AudioPhileOptimizer in my highly tweaked music server with i7 CPU (dated at this point). Last year, I installed AudioLinux (boot from USB on the same server) - my first foray into Linux. It was exactly like you described, good soundstage, lots of details and extension. But the richer texture, full bodied sound that I get from Windows Server was missing. After tweaking AL for months, I gave up and went back to Windows Server again. Last month, I tried Euphony only for few days. Really impressed with how good the whole package is. More dynamic and musical than AL. Didn't try Euphony's 100% file caching but overall while it sounded better than AL but fell short compare to Windows Server optimized with AO. There's something about this dryness in Linux sound, it gets fatiguing. I've used Windows Server 2012, 2016 and 2019. In my ears, Windows Server 2016 is the one to get (esp if you are using AO which is a must for Windows). To my ears, WS2016 smoother and organic sounding than WS2012 and WS2019.
  10. I've following items for sale: 1. SoTM clock modified (with 3 clock taps from SOtM tX-USBultra) NUC 7i7DNHE. 2. Maxed out SoTM tx-USBUltra 9V. Can be switched to 12V by taking out a jumper. Following upgrade were done by SoTM: - enable 3 sCLK-EX clock tabs(from the tX-USbultra) for NUC- Make SMB connections- Evox cap on tX-USBultra- 7N UPOCC copper stranded wire changes- Master clock input(50ohm)- eABS-200 I paid USD $1300 for the upgrade cost alone. The NUC comes with following: 1. Memory: 16GB Corsair Vengeance DDR4 2400Mhz 2. Storage: Intel Optane SSD 800P 58GB (with Windows Server 2019 Evaluation installed with AO 3.0) 3. 65W AC Adapter. 4. Processor: Intel Quad Core i7-8650U 1.9Ghz up to 4.2Ghz Turbo Mode 5. Integrated Wi-Fi support. 6. All the necessary short SMB cables. This works out of the box. Powerful enough to be a stand alone server with HQPlayer upsampling. And of course as a world class streamer! Easily bootable with AudioLinux and Euphony or use the installed WS 2019. You'll have to pay significantly more to get this quality of a music server/streamer. I'm asking $1999 + shipping from 10002. Please add 3% to the total if you are using paypal non-gift option. Pickup is welcome. I'm in NYC/Lower Manhattan. I also have the following to sell: 1. Lush^2 USB cable, 40 CM - $195 2. AudioLinux headless - $30 I will take better picture if desired by a serious buyer.

    @Miska Thank you! I've sent you email with my old key from my order address.

    HQ Player

    @Miska I reinstalled my HQP version 3.x. However, I can't seem to register. I've the old key. Online key conversion tool to XML on your site doesn't work. Please HELP!
  13. I've heard stories of frustrating experience dealing with Adrian/TLS. I consider myself lucky given that my communication was timely with him and I received the unit around when it was promised. My Ref1 worked flawlessly out of the box. However, I was not bowled over as it was only marginally better than SoTM sPS-500, LPS 1.2. It improved quite a bit after burning for 100+ hours and surpassed those aforementioned PSU by quite a margin. My Ref1 comes with teflon PCB and Vishay resistor. Yesterday, Adrian told me that proper break-in would be around 200 hours. So, I've around 100 more hours to go. Currently, I'm using it through a Equi=Core 1800 balanced power conditioner. According, to Adrian I should use directly to the wall outlet to maximize the performance. I'm yet to try that. Will report back after later.
  14. I'm probably one of the first person to have Adrian's latest re-designed PSU that supposedly closes the gap. Given that I do not have access to a SR7, I've no idea.
