  1. View Classified Jcat Optimo S ATX Linear Power Supply *PRICE DROP* Jcat Optimo S ATX in excellent condition for sale, 5500.00 € / $5,967.00 USD LIST PRICE. Original owner with low hours. This was responsible for by far this biggest jump in sound quality for a PC based music server. No need to build your own unregulated linear power supply to send power into a dc - ATX converter, this psu handles everything. Absolutely no issues running HQPlayer at DSD512 with EC v2 modulators using an Intel 12900k in a passively cooled chassis. The only time the safety shut down was triggered was during benchmarks / stress tests. If you have a similar high powered CPU you will need to make some adjustments on your motherboard’s BIOS to limit the frequency of the P and E cores so they don’t boost too high. I set mine at 4.4 and 3.5GHz, respectively. There a lot of threads on Audiophile Style discussing proper bios settings for HQPlayer. If you are not upsampling, it can power any server on the market, or any pc/music based diy project you can conceive of. Standard ATX outputs, including 8-pin CPU, HDD (SSD), and 24-pin mobo. Very high quality cables for the CPU, HDD, and MOBO are included, and a PCIE cable can be purchased separately. An ATX mounting blank and cable gland are also included for standard cases. I bought an extra 5V DC cable that I can include for an additional $125. It can be used to power one of the Jcat USB or NET cards or the revelation audio M.2 NVMe SSD (also for sale). Everything will be shipped in the original, double boxed packaging. The PSU is huge, and heavy, so please make sure you have the proper space to set it up so it can breath a little. It only gets slightly warm, but it benefits from some air circulation. Please see the link for more info: https://jcat.eu/product/optimo-s-atx/ Price is $3,850. Buyer will be responsible for Shipping and PayPal fees if not using “friends and family”. Please check my 100% positive feedback on US Audio Mart and eBay, username: Jazzebration Please reach out if you have any questions. Thanks! Due to spending most of my time these days listening to analog, I am slowly disassembling my short lived, yet beloved, music server. Individual (mostly) items will start popping up in the coming weeks, so keep an eye out if interested. The following items will all be listed at some point: - Revelation Audio SSD / M.2 FEMTO (320GB pSLC) *SOLD - Jcat Optimo 3 Linear Power Supply (dual 5V / 3 amp out for Jcat pcie cards) *SOLD - Jcat USB Card XE *SOLD - Jcat Net Card XE *SOLD - Jcat Optimo S ATX Linear Power Supply I’m probably going to regret this, as I’ve never heard digital audio sound anywhere near this good, but I’m hoping they all find some good homes. Seller jazzebration Date 01/14/23 Price 3,850.00 USD Category Power Supplies / Power Products  
  2. Hi guys, I was hoping you could comment on this. Researching for my build of a music server, I saw that the Lampizator Komputer/SuperKomputer has an internal LPSU (see image). Would you recommend this for a DIY server? If so, coud you recommend any LPSU that could do this? Thanks a lot!
  3. Hi! I have read quite a bit on those replacing ethernet switch PSU's with higher quality and lower noise versions. I did some A/B tests and could hear a small sonic benefit from moving my audio streaming from Tidal and Spotify from an intermediate Gigabit 8 port switch to direct into the ethernet ports on my DSL router (Sky SR 102). I found this video where a YouTuber suggests screening the onboard switch mode PSU and also boosting the range with external antenna.. I am wondering whether to mod this router with a linear 5v dc PSU.. Anyone experimented with this? I stream all of my music despite having a good NAS drive. Regards Simon
  4. I currently using a reasonably new Windows 10 Intel i5 HP 'all in one' type computer, which is basically lap top spec components shoved behind a rather nice 24" screen. OK, not the best machine for computer audio by a very long way, but for a variety of reasons it is what I will need to use for a while. The PC is used to run Roon core, streaming via hard wired Ethernet to a microRendu / Mutec MC3+USB. The PC has an external power supply 'brick' that delivers DV voltage to the PC. So it would be very easy to replace the supplied power supply with a decent quality LPSU. My question is would adding an LPSU afford any benefits, or would it basically be a waste of time with such a machine?
  5. Every PSU kicks some noise back into the AC line, which may have an influence on the rest of your gear connected to the same AC line. I still remember a review written by Martin Colloms of some gear using onboard SMPS, where he claimed that simply connecting said component (otherwise not connected to the system) to AC line, made his system sound considerably worse. So how bad is the problem ? Having bought a wideband AlphaLab EMI Power Line Noise Meter I decided check that out on various PSUs I had on hand. The setup To get a reference/base noise level I have used my old and trusty Audio Power Industries Power Wedge Ultra 215 power conditioner, which I normally use to 'sink' all of my computer related PSUs - main server PSU, SSD battery SMPS charger, UpTone Audio JS-2 powering two LPS-1 PSUs and a computer monitor. The noise level measured at the output was just 23mV. I have used one of outputs to connect a simple power strip (with no filtering): [/img] The PSU under test was connected to the same power strip, next to the EMI meter: I had 8 different PSUs on hand: 3 linear ones and 5 SMPS (switch mode) types: [/img] 1. Teddy Pardo linear PSU 2. UpTone JS-2 linear PSU 3. SOtM supplied SMPS (PowerTek) 4. Meanwell SMPS (supplied by UpTone with Regen and LPS-1) 5. Some generic linear PSU I found lying around 6. Ktec SMPS that I got with an external HDD 7. iFi iPower SMPS 8 Co Ming Data SMPS Since I have observed the level of noise beeing kicked back to the AC line varies with PSU load, I have measeured those PSUs in the following conditions: 1. Idle - PSU connected to the power strip, but nothing connected to the PSU (no load) 2. Noise under light load - PSU powering Regen, which in turn was powering AQ DragonFly DAC 3. Noise under moderate load - PSU powering SOtM sMS-200 4. Noise under heavy load - PSU powering the LPS-1 Ultracapacitor PSU, which in turn was powering the SOtM sMS-200. The results I got are as follows (green = best case; red = worst case): Please note that the smallest, generic linear PSU (last column) was not tested with LPS-1, since its power rating was too small. Some things I have noticed: The SMPSu in general injected much more noise than linear ones. Even the cheapest generic wall wart linear PSU was better than the best SMPS. In many cases, the noise figures dropped at idle a few mV below the reference level. It is my understanding that this is due to filtering built at the input of those PSUs, which interacts / lowers the noise on the AC line. The PSU noise readings were jumping up and down when the LPS-1 PSU was connected (chence the results are in ranges). You can see this on a short video I uploaded on youtube. It is my understanding that noise spikes were caused by the LPS-1 bulit in (capacitor) charger - when the charger was running, the noise was higher; when the charger was idling, the noise was lower. I'm not sure if higher noise readings are caused by higher current draw or the noise is comes from the LPS-1 charger itself. Whatever the reason - some PSUs were much more sensitive to that than the other. For kicks, I have also measured several other PSUs and even light bulbs: - iPhone, iPad and MacBook chargers are pretty harmless when at idle. I wouldn't want to have one connected to my powerstrip when charging though (all of you using MacBooks and other laptops connected to your system take note). - CFL light bulbs (and LEDs) are huge noise generators (unlike regular light bulbs, which generate close to zero noise). - chineese iPhone charger knock off from ebay, creates some absurd amounts of noise - many times more than the original Apple accessory (one more reason not to buy knock offs). - TeraDak linear ATX PSU that powers my CAPS v4 Pipeline server generate generates only 48mV of noise - suprisingly litte. Final notes: If you have lots of those generic SMPS around your audio system (powering DACs, HUBs, routers, external HDDs etc), it probably makes sense to replace them with something designed with the AC noise pollution in mind, like the $49 iFi iPower SMPS for example. Linear still seems to work best though. Having said that, please remember, that the best PSU is not necessarily the one which kicks the least amount of noise back into the AC line. The best PSU is the one that has low AC noise footprint and offers stellar DC output performance.

(PF have verified voltage requirement) I am interested to know if: the setup should be left alone - as is? (i.e. just PICO?) OR is it possible to put a linear regulator on the PATA/MOLEX 12v line for the i2s card? (what device would be required?) is it possible to put a linear regulator on the CPU 12v line for the CPU? (what device would be required?) OR Have a seperate LPSU for the PATA/MOLEX 12v line for the i2s card? Have a seperate LPSU for the CPU 12v line for the CPU? Please refer to picture! Many thanks!

  8. Hello all, I think I've read lots of tips here, about how to get the better sound from your SSD/HDD/SD card or other internal/external storage device (FW and Thunderbolt : good, USB : garbage...), but did anyone tried to connect his SSD/HDD to the internal PCI-e or mini PCI-e output of the Mobo ? I read that the reason why Mac Mini's did sound quite good with the Thunderbolt external disks was because it was powered from a mini PCI-e bus (?). I have a mini PCI-e output I don't use on my HDplex PC mobo (I removed the wifi card who was there...). Do you think I could gain something with a mini PCI-e to USB or Sata adapter ? Something like this : Carte Mini PCI Express USB 3.0 - Vente Carte Mini PCI Express USB 3.0 sur conrad.fr | 986875 (french link, sorry) My current stting is an external usb 1 To SSD with a 3.0 short cable to my HDplex PC, but powered with a Teddy Pardo 5v PSU (usb to 3,5mm mini jack). It's already very good to my ears : about the same that internal Sata , but it was too hot to let it there... So, can I expect something better with mini PCI-e + 5v power through external PSU, or is it just bullshit ? Thanks for any advice.
