Marcin_gps Posted July 16, 2018 Share Posted July 16, 2018 @One and a half Thanks for the report. I see you've not watched (listened) the entire A/B for the reasons you've stated. But if you have time please check the 2nd part when Tidal is streamed via JCAT NET Card instead of the motherboard's network interface. You're up for a surprise JPLAY & JCAT Founder Link to comment
asdf1000 Posted July 16, 2018 Share Posted July 16, 2018 Interesting video and observations. I'd be interested to know if he'd hear similar differences with the music server far away from the HiFi setup, in a different room (where a music server should be).... ...where the music server sends raw PCM or DSD (from either HDD/SSD/cloud streaming) over the network to a renderer like a Sonore Rendu... I used to hear differences when my music server was direct USB connected to my USB DAC but from my own experience and observations (not any expertise) these differences get much smaller when the server is far away..

Marcin_gps Posted July 16, 2018 Share Posted July 16, 2018 But then how do you explain the differences with TIDAL stream? Tidal servers are far far away JPLAY & JCAT Founder Link to comment
asdf1000 Posted July 16, 2018 Share Posted July 16, 2018 Just now, Marcin_gps said: But then how do you explain the differences with TIDAL stream? Tidal servers are far far away The decoding of the FLAC is still done the music server - which in his case is still next to all his HiFi gear (analogue components in particular).. As I mentioned, when I moved the music server far away, then all decoding is done far away and only raw PCM and raw DSD is sent over the network to a renderer like a Sonore Rendu. And this is where the differences between Tidal and HDD/SSD disappeared for me. Only my observations and as I mentioned I'm not pretending to be an expert. It's all interesting and love reading everyone's observations ? Marcin_gps 1 Link to comment
asdf1000 Posted July 16, 2018 Share Posted July 16, 2018 I should also add that John Swenson has talked about the importance of signal integrity even applying to ethernet physical interfaces, so even in the setup I describe where a music server is far away from all the HiFi gear and feeds something like a Sonore Rendu, I actually would expect things to sound better with this JCAT net card femto fitted to the music server. I only mentioned the above to share how difference between Tidal and HDD/SSD reduced for me when moving the server away. I'd still expect a very nice boost overall (to both cloud streaming and local drive) with something like this JCAT card fitted to the music server. If only you could make one compatible with Intel NUC @Marcin_gps ! ? Maybe? Link to comment
Popular Post Marcin_gps Posted July 16, 2018 Popular Post Share Posted July 16, 2018 @Em2016 Exactly The card is compatible with NUC. You just need to use a M.2 to PCIe riser cable, sth like this: And probably a bigger enclosure... Otherwise, it will look like this But it works. BTW - I don't believe that a music server should necessarily be away from the main hifi system. Only if it's noisy it should. If it's a relatively low TDP, powered by an LPS etc - it can sit right next to the system as another hifi component. Best regards, Marcin ferenc and asdf1000 2 JPLAY & JCAT Founder Link to comment

Do you have any clients using it with a Linux based OS / distribution on Intel NUC? Any special drivers required or it works straight out of the box? Cheers! Link to comment

Drivers for Linux are available from intel and can be downloaded here I have many customers using the card with Linux. The customers who use the card in NUC use Windows, but it will work fine under Linux too. Best regards, Marcin asdf1000 1 JPLAY & JCAT Founder Link to comment
Marcin_gps Posted July 17, 2018 Share Posted July 17, 2018 There is a new A/B video which demonstrates the difference in the sound of locally stored files on SSD with music server connected via onboard LAN & via JCAT NET card: JPLAY & JCAT Founder Link to comment
One and a half Posted January 25, 2019 Share Posted January 25, 2019 Today added a Kingrex PSU MK-II 5V 3A Linear PSU to the NET FEMTO card. Lydian Collective's Loops has a very active drum sequence in the middle of the track, quite a tough ask for any audio system to playback. That so far has not been that clear, Sophie Alloway's very quick rendition, so far being obscured by the mix, but the linear supply has removed some grunge to reveal every beat and cymbal, which is rather a nice touch. I imagine a 'better' PSU may offer different results, the Kingrex has a 3 standard terminal regulator, the low noise types arrived a few years later have a better noise performance, the Kingrex was idle doing nothing, so thought to give it a shot. AC input is balanced power. @Marcin_gps, I see both the 400W and 200W PSU are out of stock, can you tell what principle regulator is used and how fast the overvoltage protection works. There a hundreds of linear PSU, but so far unable to see a fast reacting overvoltage protection, like 150% for 300ms, that will kill a 5V circuit. What's the voltage tolerance on the JCAT NET FEMTO?

Somehow I missed your message Regarding PSUs, you may see the details on hd-plex website as these are from hd-plex. Maximum temporary voltage that the NET Card FEMTO will tolerate is 10V, but it is not safe to run it like this. Up to 20% voltage tolerance should be safe. I'm glad you're enjoying the sound with the NET Card! Regards, Marcin JPLAY & JCAT Founder Link to comment
austinpop Posted March 24, 2019 Share Posted March 24, 2019 I posted a system review on another thread which featured the JCAT Net Card Femto, so posting a link here for those interested: Marcin_gps 1 My Audio Setup Link to comment
mourip Posted April 3, 2019 Share Posted April 3, 2019 Once installed will the Femto card be automatically recognized by Windows 10 without the need for special drivers? Are there any settings for the ports that are beneficial? I have one ordered and will use it in bridged mode... "Don't Believe Everything You Think" System Link to comment

thuandb Posted April 3, 2019 Share Posted April 3, 2019 Once installed and restarted, the card will be recognized by the OS. However, in order to get the max performance you’ll want to download and install the latest Win 10 driver from Elan120’s link. Adjust the settings according to the included guidelines. mourip 1 WS2019 Core Datacenter, dualPC, JPLAY Femto, AO3, Fidelizer Pro 8.8, MC2XY, IOS app. Link to comment

Ricardo007 Posted May 10, 2019 Share Posted May 10, 2019 One question from a network audio beginner: On JCAT link: http://jplay.eu/ml_post_slider/jcat-net-card-femto/ there are 3 scenarii for use of a JCAT NET card femto. In scenario 1, question 1: do you NEED to bridge the 2 ethernet ports on the JCAT card? question 2: Is bridging possible if you use DAPHILE on the server as an OS? In scenario 3, called dual PC setup, especially for JPLAY users (but only?), there is a "control PC " and an "audio PC". To my understanding, this is a 2 box solution like scenario 1 where you have a "server" and a "player". So what is the difference between the 2 configuration (dual PC versus separate server and player)???. In scenario 3 diagram there is no connection of control PC to a router so only local playing, no streaming? Link to comment

In that situation, that's yes, since the router and the Player need to see the same network, the only way to do this is to bridge the adapter. 3 hours ago, Ricardo007 said: question 2: Is bridging possible if you use DAPHILE on the server as an OS? Daphile is Linux? Don't use this, sorry, no idea.I thought Audiolinux or Euphony was the FOTM. 3 hours ago, Ricardo007 said: In scenario 3, called dual PC setup, especially for JPLAY users (but only?), there is a "control PC " and an "audio PC".

The last scenario is the server has local files and send to the other PC. you're right, no external network streaming possible like TIDAL, SPOTIFY, QOBUZ., unless you bridge the server to the router with another Ethernet card With Daphile?

Mine was delivered yesterday so it may have something to do with your tracking not updating or waiting for pick-up. I hope you’ll receive it soon! (and I can tell you it’s worth the wait, installed cold with a brand new PSU I can already clearly hear the improvements; so much more micro detail/less smearing which’ll give improvements over the whole range!)

Thanks Dutch. I am curious. I am in the US. Are you? My tracking information still shows the card still in the UPS warehouse in Poland. It arrived there 4 days ago. I know that the tracking could just be off but it is consistently updating the location daily. I wonder if any others have their card stalled there? Marcin said that he will look into it on Monday...

No, I’m much closer to Poland. I’m based in The Netherlands. Marcin is in Munich at the High-End show right now, hopefully he can find out what’s causing the hold-up Monday. Good luck!
