Aside from a host of Fluke tested Cat5e, Cat6, Cat6a S/STP from many manufacturers, I had a lot of Belden bonded cables that were terminated and tested by Belden. I seriously think length should be more looked at among people who hear differences due to ethernet cables. Varying the cable might result in a different or better sound as it can perhaps make it easier for the PHY. Rather, I think the cable and it's electrical properties (impedance, return loss), while especially focusing on length, may be influencing the behaviour in the PHY (which may be sub par) in some of these devices. But as far as any double floating shielded cables or any Fluke tested and passed UTP cable from any manufacturer sounding different from another, I don't think it's the cable itself influencing the sound by picking up more noise or letting more noise out. bridged connections.Īlthough, I don't think the cables themselves are creating any problems, aside from any shielded cables that are grounded which is another issue. I did find Roon in my setup with my endpoint to be sensitive to the cabling, power supplies, and/or routers vs. On the other hand, Roon is a lot more stable. Audirvana Plus worked better for me, but it wasn't perfect either. I gave Minimserver and Linsky a shot, but it was problematic for me. I tried to use some of the UPNP/DLNA on Mac, but found it troublesome. In the FWIW column I experienced that UPNP/DLNA play was sensitive to Ethernet cables whereas Roon with its RAAT protocol was not. I wonder if they might be actually making things worse or just making things different and just taking a shot in the dark. So when I see any devices or solutions being offered by manufacturers, I do question the merits and whether they are actually correctly tackling a problem, or are even aware of what the problem might be. I know how things sound in my rig and what patterns emerged. You need measurements to really test these things.Īfter all this time, some things make sense, while others still don't. Other things like signal integrity and cable reflections becomes hard to experiment on like with noise above, aside from blind testing. You can make up logical experiments at home to test for this. Noise is often discussed as a 'problem'.it's either noise that's coming IN, or noise going OUT, or noise already on the cable. It's good to systematically experiment and see if you are actually affecting the variable that you THINK you are affecting. In some cases, my own results went against what most audiophiles think, but does agree with networking specialists. In other cases, I found why some people might even like some things are not good, especially in short-term listening. Some things worked as expected, and results were in favour with the established knowledge. I spent the past few months looking at this area and meticulously experimenting with lots of devices (10) and cables (30+) and testing out the various assumptions that people seem to have and what is already established. Anyone who would like a good deal on some FMC's and fiber feel free to PM me :-) I am however enjoying having the less complex setup. Obviously there are other factors that could come into play such as my grounding and AC isolation system or the decreased load on my multi-outlet LPS's. I could not, and so went back to a simpler system using just copper cable. I used an LPS on the server side.Īfter using these for a while I decided to remove them to see if I could hear a difference. I also used FMC's for the link between my server's second ethernet port and my LAN switch. Basically I just strapped them together and used the shortest lenght of fiber I could find to connect them. I used a pair of FMC's for a while to isolate the ethernet link between by Dante based Focusrite D16 and my music server. I'm hoping we get to see pics of the inside board/s to see what they're really doing in there The price is very high though to replace a pair of cheap FMC's with one box, unless it has some other features like nice internal power supply etc. I guess it appears to function like a pair of FMC's inside the one box, with one 5Vdc power input.įor background I do use a pair of TP-Link FMC's and I've been looking for a one box solution. Has anyone had any experience with any of their products? This is a brochure for their older model: Brochure.pdf Their "FOIL" trademark stands for fiber optic isolation link so I assume it really is fiber optic. I posted about this in another thread but it goes lost in the SOtM Trifecta chat :-)
