No. Although I'd recommend updating the driver from intel once in a while. Regards, Marcin

Thanks Marcin. I did follow your excellent guide when I bought my card last May. Are there any new configuration changes that would apply specifically to WS2019? Thanks!

'One thing that’s clear about the JCAT Signature LAN cable – it doesn’t sound like any other Ethernet cable I’ve heard. It’s the most transparent, quickest, and quietest Ethernet cable in my arsenal.' 😊 Link to the full review below https://audiobacon.net/2019/11/02/the-jcat-signature-lan-a-1000-ethernet-cable/ Regards, Marcin

There is a guide I wrote available for all customers who purchased the card. Please send me a PM if you have not received it. The article is not publicly available - it's a free bonus for everyone who purchased the card. Regards, Marcin

Yes, running WS2019 Core with JCAT usb and net Femto cards with great SQ.

I do not think it's the OS. What bothers you? I got very good experience configuring the network card following this guide: Computer Audio Best Practices Guide: https://pdf.highend-audiopc.com/computer_audio_best_practices_guide.pdf You should also change some settings in the network adapter. For example, disable Interrupt Moderation and Green Ethernet (reduces latency). Did you load the latest drivers? There is a lot to consider and it would be nice to get a compendium of the recommended settings from JCAT.

I am still enjoying this card but feel that my server OS is holding things back. Has anyone used it with Windows Server 2019? Thanks!

Good to hear! Give it a good burn-in (about a week) and it will sound even better. Enjoy! Best regards, Marcin

Thanks, that's all set up and running nicely. I'm using an EVGA Z370 Micro which has very pleasant and open sounding USB ports on board, but it lacks the rhythm that my older gaming boards such as the Maximus VIII Impact had. Listening with the JCAT installed it seems to have got its rhythm back. There's also more detail and weightier bass than before, so all good so far. 😀

JPLAY manual is now available in Japanese too: http://jplay.eu/日本語/ Regards, Marcin

Thanks. I hope you will be satisfied with the performance. 1. It has the latest 2.0 firmware 2. If you want to double check, please run the firmware again - it takes only a few seconds: https://jcat.eu/usb-card-femto-gets-a-free-update-to-ver-2-0/ 3. I'd remove all jumpers from the card. Then only the USB chipset and the clock will be powered (no 5V via USB ports) Please let me know if you have any further questions. Regards, Marcin

I've just ordered mine in the hope it will be delivered before Bexit. 😱 My SoTM card broke and the PPAv2 was never as good as the SoTM one. So now I'm hoping the JCAT is better than both... Can I check a few things though: 1. If it was dispatched from Poland this week, which version of the firmware will it have? 2. How do I check the firmware number? 3. What are the best jumper settings to drive an original HiFace EVO with a single USB cable and powered by a MCRU 5v LPSU? I don't believe the EVO needs power from the USB port, but I'm not 100% sure on that (I could toggle the ground-lift switch on the back of the SoTM card without issue) and the MCRU should provide decent regulation. Thanks

Exactly. And using a good linear PSU with the USB (or NET) card unveils true potential of the USB connection for audio playback, which some people consider not worth using in a high-end audio system. The full USB chain must be pristine in order to enjoy sound quality at the highest level. Regards, Marcin

Which goes to prove that using 'raw' USB from a desktop/server/laptop should not be used. Although I don't use the Femto USB board everyday now, it was a no brainer to install the JCAT net Femto for Ethernet with similar results.

I can confirm that too as I am listening to a computer I just built for a friend of mine. Switching from the JCAT to any of the motherboard USB ports collapses the entire sound stage, makes the sound flatter and harsher, the bass becomes boomier with less accuracy. Also, some motherboard USB ports sound better than other, but the JCAT USB output is way better. The good thing is if one wants to hear what 'jitter' sounds like in digital audio, the switching between the JCAT USB output and the motherboard USB makes it really easy to hear :).

Thank you!

This is great Marcin. Glad to you you have you own space here!

Right you are, Chris. You're two of the nicest guys I know in the industry. Joel

Thanks, Chris

Hey @Marcin_gps, welcome to your own space here at Audiophile Style! I know many of the members of this community will be happy to see you here, including one @joelha :~)

JPLAY can not play to external network renderers. Regards, Marcin

From my memory, yes. With help of Sonore's UPnP app. It is based on the UPnP/DLNa-bridge plugin for LMS. I had the microRendu and it worked rock stable. Please have a look at the manual 'How to use JPLAY FEMTO with Roon?'. You don't need to do the first four steps just activate the LMS support in Roon and activate the UPnP app on your Sonore endpoint.

Sorry if this has been answered (I couldn't find it) but can jplay be used with Roon and a Sonore endpoint such as an ultraRendu?
