ETHERNET CABLES


When using ethernet for hooking up streaming devices and dacs, what cat level of  ethernet cable should be used. Is there any sonic improvement by going to a  higher dollar cat 7 or 8 cable?

@juanmanuelfangioii what is the purpose of this equipment? I don't even understand what it is supposed to do.

Fiber/Optical is taking out any emi rfi and cleaning the signal up.

Similar to using the small green computer optical isolation bundle 

Was a thread on this at one point. 

  • Seamless Conversion of LC Fiber to Copper – This fiber optic to ethernet media converter kit includes a multimode 1000BASE-SX SFP module(850nm), which enables you to convert 1000BASE-SX LC fiber to 10/100/1000 Base-T RJ-45 copper media or vice versa
  • Extend Your Transmission Distance – By using this ethernet fiber media converter, you can easily extend link distance up to 550 meters/ 1804 ft via OM3/OM4 multimode fiber (MMF, LC, Duplex)
  • Plug and Play – No software installation or configuration required. Hot-swappable design makes this ethernet fiber converter easy to install and troubleshoot
  • Reliable Auto-Negotiation Gigabit Connection – 10/100/1000Mbps Auto-Negotiation RJ45 Port supports Auto-MDI/MDIX Crossover and Half-Duplex / Full-Duplex Transfer Mode, bridging different network speeds and devices to a Gigabit fiber network

I work with computers and a cable isn’t going to do anything. 1’s and 0’s are going to be the same 1’s and 0’s on the other end. If they aren’t then you dont get a correct signal and are dealing with other problems. These fancy cables dont “massage” the 1’s and 0’s to make them sound better.

I've used a similar kit by TP Link between my router feed and Node N130.

It's a no brainer for the relative small outlay. It helped my Node no end, noise floor decreased significantly. Much more relaxed, and no longer "grainy" 

My router is in the next room where the TV, Sonos, BRay player, Phillips Hue Bridge, TV Cable box all live and feed from - quite a lot going on/noise. The kit in the above post puts a fire break on all that noise transferring to your streamer via ethernet. 

Granted, the 2nd convertor in the chain introduces its own noise, but this can be reduced by swapping the stock wall wart for the convertor with an ifi low noise power supply, or something similar. 

 

@dpcoffey Great to see someone who talks some digital sense. I fully concur, never understood how 'audio grade' ethernet cable, or USB cable can make a difference. All other data is transferred error free ... bar audio?

"I did notice a sonic difference when purchasing and switching to an ethernet Audioquest cable"

I won't say you didn't hear a difference, the brain can do funny things. But let's analyze this together. If the sound difference stems from receiving 'better' digital data since you installed the new cable, this means that the old cable introduced errors. Let me ask ... when you browsed the internet, did you ever see spelling errors in the texts? Or pictures or video come in corrupted?  Or when you downloaded apps, or Windows updates, sized many MB or GB, did they work? I bet this all was fine? So, only streamed audio contains errors? Isn't that weird? (OK ... I give you this ... Windows updates can sometimes be weird. :).
