audio isn’t digital since analogue noise messes with the subsequent D/A signal conversion; i.e. RMI/EFI or ground level noise matter in audio, not digital.
Ethernet
I am adding a HiFi Rose RS 130 to my set up and need to split my ethernet cable run... Here is my question: I have about a 20' run into the splitter , then 2 x 3' runs to the RS130 and a BluSound Vault. I have been using a $20 ethernet Cat 5 cable on the BluSound Vault alone. I am seeing (typical) ethernet runs for $7,000 to $1.50. Where do I go here? Primary goal is to make sure all 3 runs are identical and really NOT thinking of spending a ton here. Thoughts? Cat 5...6...7...?
Help !!

@antigrunge2 - where does it mess with USB and how? SPDIF - sure. This is why no one should be using coax. I am yet to hear explanation on USB. Ethernet even more resilient. Everything is retransmitted if there is an error. Again - your email does not change no matter fiber, electrical, satellite links and 100 times conversion of electric to optical to radio and back. It comes to you 100%. So is the FLAC file. |
o2 +1 for Supra Cat 8+ cables, been using them for a while; and a terrific value (and really good performer)......all of their cables are good performance for the money. As mentioned, they are made in Sweden to very high quality.....and are lesser known in the US. The official distributor for the US sells on eBay under the name sjofn HiFi, it's legit purchase. They have lengths from .5 meter up to 30 meters |
you need to read up on this: fiber does not suffer from the noise incursions I highlighted but from noise generated during ethernet to fibre conversion. The problem isn’t that packets get truncated or don’t get there at all; it’s that the noise travels along the packets on the wire, whichever you chose with deleterious impact on the D/A conversion. and btw: why do you think people offer USB cables where the 5V line is separate from the signal lines?

@mikhailark I happen to know exactly what Amazon uses in their DC's for cables. The same cables almost every company used, just Belkin. To the top of rack switch them fiber from there. Fiber optic does not carry any noise. It's just light pulses. Nothing in a computer system has the power to create noise. You can get some distortion in the light with very high magnetism. Usually noting in the DC has that kind of power. You can also bend the cable too much, but when using real glass cable it's lets you know how much of a bend you can put in it. The key to fiber is the SFP at the end, that is what really matters with fiber. The way Ethernet packets work, don't see how an expensive cable will really work any better. The key is to have a certified cable, that is properly attached to the ends. Packets are not all sent in the proper order some are sent more than once. They are compiled on the end, the end unit sends back packets saying it got the packet, the percent it received. It's not a constant stream, but a ton of small hand shakes, packet sent, packets received, etc.. It's all digital, every hop it goes through along the way, the packets are resent from that device. Each hop is decoupled from the previous device. Any "noise" or anything is really only in the final hop to the end point. If there is anything wrong with the packet after it is received, it will be sent again. |
