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 !!
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. |
@mswale - exactly. Decent shielded and properly soldered cable, that's all. I am familiar with switching network protocols :-) |
@antigrunge2 - please explain what is exactly "noise travels with packets" and how exactly does it affect the DAC. Packets are reassembled into bit sequence upon receive in the network card. There is no analog noise there. There is no noise in the CPU. No noise that would affect code execution.I have no idea why they offer it, there are $1000 Ethernet "filters" so I am not surprised there are USB connectors with Japanese wood covers. Once again - does Apple or Amazon use "special" cables? Is there difference in USB transfer speed to an external drive with and without separate power? |
Cops in NYC ride around in Toyota Prius and Ford Explorer. I’m sitting here struggling with a decision - do I dump my BMW cause it’s a scam and get into a Prius or would Explorer be a better choice. After all it’s only a ride from point A to point B and it doesn’t really matter - I’ll reach my destination in a Prius just fine. I might be pissed off and in an extremely bad mood which would impact my productivity. But who cares. I’ll get stuff done anyway. Right? What do you think @mikhailark ? When we’re talking about Ethernet or USB, being confident that the data will get from the source to the target if you’re using a cable that meets specifications and requirements doesn’t mean you understand how it is possible to control how Ethernet cable can impact the sound of your streamer. We’re not processing your refill of multi vitamins as part of your amazon order. We’re streaming music which is a completely different space and every component matters. |
