  1. @auricgoldfinger thanks for the report. How do you like the Optimo? Regards, Marcin
  2. End of Summer. I will start a new topic with more details and some pictures from the lab. Regards, Marcin
  3. 1. 3.3V 2. The filtration and noise reduction is provided by the LDOs. You can see the exact specs here: https://www.analog.com/en/products/lt3045.html#product-overview 3. I don't know. But I can tell you that the PSU for the PC is still quite important and easily audible, if that was your question. As a matter of fact, we are in the process of designing a high-power version of a PSU for a PC. Regards, Marcin
  4. ⚡️Our OPTIMO 3 DUO linear power supply was reviewed by Wojciech Pacuła, chief editor of renowned HighFidelity magazine. Wojciech used the OPTIMO 3 DUO to power Mytek Brooklyn Bridge DAC/network player and wrote that the PSU added the biggest improvement that he applied. 🤩 The article is available in Polish for now. The official English translation will follow next month. For now, please use Google Translate. http://www.highfidelity.pl/@main-3722&lang=
  5. Did you by any chance remove the jumpers from the card? I wonder if that's the cause.
  6. Thanks for the suggestion. It's interesting, but a USB Card is only one piece of the music server puzzle. I think the results may vary quite drastically depending on motherboard, power supplies etc. Regards, Marcin
  7. linear PSU for the motherboard is certainly good, but a separate LPS for the card is a different story. I'd strongly recommend a LPS just for the USB Card XE Regards, Marcin
  8. NEXT BATCH UPDATE I'm afraid I have unfortunate news. I've just received an email from Digi-key regarding availability of the OCXO oscillator we use on the USB Card XE. The original shipping date when we placed the order was June, 6th. Now the date is June 30, 2020, with an additional, approximate 6 business days transit from the manufacturer to Digi-Key. The SiT5711 is popular and SiTime has not been able to get ahead of the demand. Regardless, we are pushing to get the oscillators sooner, but it seems that the USB Cards XE will not ship sooner than in July. I know this is disappointing, but there is very little we can do. I will keep you updated. On the bright side: Best regards, Marcin

  10. @ray-dude what a great and comprehensive report! And great to read that you're enjoying JPLAY Looking forward to the next part.
  11. Hear the difference our OPTIMO 3 DUO linear power supply makes 🎧 Terry Ellis, the reviewer behind Pursuit Perfect System, was impressed so much with the PSU, that he decided to keep it as the part of his reference system! 👽
