dminches Posted December 10, 2019 Share Posted December 10, 2019 I installed my card yesterday and followed Marcin's guide in order to set things up and adjust the card's settings. I am powering it with a 5V rail from my HD-Plex 400W LPS. Have people experimented with any of the settings and have anything to share? I plan on letting things play as is for a while but then I may adjust things. Marcin, which are the most influential settings that you would recommend people play with? Speakers: Vandersteen Model 7s, 4 M&K ST-150Ts, 1 VCC-5; Amplification: 2 Vandersteen M7-HPAs, CI Audio D200 MKII, Ayre V-6xe; Preamp: Doshi Audio Line Stage v3.0; Phono Pre: Doshi Audio Phono Pre; Analog: Wave Kinetics NVS with Durand Telos composite arm; SME 3012R arm, Clearaudio Goldfinger Statement v2; Reel to Reel: Technics RS-1500; Doshi Tape Pre-Amp; Studer A810, Studer A812, Tascam BR-20; Multi-channel: Bryston SP-3; Digital: Custom PC (Sean Jacobs DC4/Euphony/Stylus)> Lampizator Pacific Link to comment
StreamFidelity Posted December 10, 2019 Share Posted December 10, 2019 The instructions from Marcin are great. Unfortunately a bit dated. I did'nt found all described settings. Of course I use the latest Intel drivers. But everything runs optimally with the guide. I had experimented a lot with the settings before. Also with the tool SG TCP Optimizer. That was'nt succesfull. I'm convinced that lowest latencies are the key factor in streaming. I therefore test each setting with the tool LatencyMon.

I'd check 1Gbit and 100Mbit link speeds - this is the biggest difference. Regards, Marcin dminches 1 JPLAY & JCAT Founder Link to comment
Marcin_gps Posted December 12, 2019 Share Posted December 12, 2019 Actually, if it's not a problem in your scenario, 10Mbit also sounds great, but make sure to set it to full duplex. JPLAY & JCAT Founder Link to comment
StreamFidelity Posted December 31, 2019 Share Posted December 31, 2019 Hi Marcin, are there any considerations to offer an optical fiber connection at some point (e.g. Asus XG-C100F 10G network card SFP Plus Port)? I'm asking because my switch SOtM sNH-10G has two SFP ports.

I'm asking because my switch SOtM sNH-10G has two SFP ports. Regards Gabriel My system is set up with a clean side and a dirty side with isolation using a big transformer. My server was connected to the LAN side with an optical cable using FMCs. The FMC on my clean side was powered by an LPS. My FEMTO card has the two ports bridged with one port going to the LAN and the other directly to my Roon endpoint. On a lark I decided to remove the optical isolation and just use an ethernet cable to my stock Cisco router. To my surprise I liked the sound better. Perhaps the issue was with the FMCs themselves? Perhaps sometimes simpler is better? I am just pointing out that for me in audio sometimes theory does not always account for what I subjectively experience. Or perhaps I am working with the wrong theory or do not really have a good handle on it? Either way the FEMTO card has been an excellent addition to my system, surpassing the two port bridged Intel card that it replaced.

mourip Posted January 30, 2020 Share Posted January 30, 2020 Hi Marcin, Have you ever considered adding an input for a 10M reference clock to the Femto card? Is this something it might benefit from or does this even apply to the way the card works? I am considering adding a EtherRegen switch to my system. It allows for a 10M reference input and so this thought came to mind. Best, Paul "Don't Believe Everything You Think" System Link to comment

FelipeRolim Posted February 6, 2020 Share Posted February 6, 2020 I bought the JCAT USB Card FEMTO a year ago, and I'm still postponing the purchase of the Net Card FEMTO. I need two units., but it seems better to wait a little longer, hehehe... Link to comment

ASRMichael Posted February 18, 2020 Share Posted February 18, 2020 Re Femto Drivers. As owners are aware when you purchase the Femto there is a guide on how to get the best SQ by changing driver settings, well in Windows at least. As for Linux I believe it's just a generic driver. Generic what does this mean? it simply doesn't have all the settings Windows driver has, so can't be optimized?, is it an inferior driver?, if so, then can the driver be improved?/optimized?

Try the AudioLinux thread here. I am pretty sure some of those folks have used the Femto card with AL and they are a very collaborative group.

Where I’m still pondering how the 5ppb oscillator would fit in 🤔 This is a prototype of a music server that I showed in Munich last year. There have been new developments since then which will delay the music server. Regarding smaller endpoint device, I've been working on it for quite some time already - designing a computer from a scratch is a complex project... Regarding 5ppb oscillators - these are small these days, you will see. Anyway, this is OT discussion. FredM 1 JPLAY & JCAT Founder Link to comment

It seems like this can be done with a sequence of "ethtool" commands, but there may be a cleaner way using a config file somewhere. My Audio Setup Link to comment
