I'm wondering if someone can recommend a LPS.   I have received my card but as it really needs an external power supply and I cannot find one, it's not going to be much use to me.  I have searched for LPS 5V/2A and haven't found anything that seems to be a complete product (most things I find appear to be circuit boards).

 

Thanks in advance!

200W Linear Power Supply

 

There are cheaper alternatives too on ebay. It can be more than 2A. It's ok.

Hi there,

 

Here comes a short report from my experience with the new network card.

 

I'm very happy with the sound of the JCAT NET card. I expected listening to streamed internet radio would benefit most but I discovered that listening to wav-files from the SSD using JPLAY Streamer sounded better than HYSOLID which was a big surprise ;-)
 
Both USB Femto and NET card Femto are powered with the 200W linear power supply and I have the most natural and musical sound ever.
 
Best Regards

Thanks for the report! :)

It's fascinating that the sound benefits so much even for files stored locally in singlePC mode. JPLAY uses network internally, but still, I did not expect such an improvement in single PC configuration. 

 

Best regards,

Marcin

Here is a report from a customer that might be helpful to anyone who'd like to use the card, but his PC does not have a PCIe slot, only Mini PCI-E:

 

I received my card today and had zero issues connecting it to my mini-itx system.

Since my mini-itx doesn’t have a pcie slot, I had to purchase one of these ($17.75 + shipping USD):

Hi Marcin long time no see. I'm also thinking of getting a femto but have a few questions:
1. when's the second batch due?
2. my configuration is tidal->controlpc->audiopc->jkeny hiface 2-> Weiss Dac 2. should I be using a network bridge instead of going through a router?
3. will femto card prevent network disconnects?
thanks!

Hi! 

 

Ineed, it's been a while :)

1. End of October, but I still have 3 cards left from the first batch ready to go ;)

2. Yes, I think for TIdal, bridging is best choice. In my dualPC setup I prefer using only one port on the card in each PC and disabling the 2nd one. But my music library is storred locally, directly on controlpc. For music library in the cloud (streaming services) or on a NAS, I'd recommend bridging. 

3. Not sure I understand the question? I haven't had a single disconnect for months, but it was also the case when I used integrated ethernet. 

 

Please let me know if you have any further questions. 

 

Best regards,

Marcin

Thanks! Yes I'm not too familar with integrating ethernets.
Basically I use my controlpc to stream from tidal.
So I understand that I'll need a second network adaptor in the control pc right?
1. original onboard NIC connects to router
2. FEMTO in control PC connected directly with audiopc
Am I right?

Not necessairly. Some customers say that using both ports on the card (one for network, one for streamer/audiopc) sounds better. Best to check what you prefer in your setup

 

BTW - sound quality will gain also for local files, not just Tidal :)

 

Best regards,

Marcin

Marcin,

I am a bit puzzled by this as I would assume that network bridging makes even more sense when the music library is stored locally given that a noisy switch is not requied to access files stored on a NAS, etc.?

Marcin, are you storing your music files on a HDD on control pc?

You are right. I'm simply stating facts that using just a single port in my system is better than using both simultanously. But I don't use NAS. 

I recommend trying both options:

- bridge 1x onboard port for home network and 1x JCAT NET port for streamer.  

- bridge 2x JCAT NET ports for home network and streamer. 

 

Marcin, are you storing your music files on a HDD on control pc?

Yes.

In case anyone wonders how JCAT NET card affects playback in an Audio over IP system (Rednet), here's the feedback: https://www.head-fi....5#post-13729744
