The Shunyata Research OMEGA-X-Ethernet Cable

@seymour-krelborn 

The OP focus is on the network Ethernet cable.  You are focusing on the DAC.  

We agree data packets transmitted over the Ethernet can be corrupted.  The bits travel on an electric current and any electrical anomaly can cause corruption. Think of streaming television where, in an electrical disturbance you can have screen dropouts.  
 

What I continue to stress is that Ethernet protocols are robust with built-in error detection such as CRC (Cyclic Redundancy Check) and imbedded check code sequences that flag an error. The Ethernet protocol will simply request that packet again.  Streamers and DACs do no rely on corrupted packets;  rather, they buffer until  a correct, complete packet is received.  So, in a well-functioning network, you won’t hear sound quality issues because the data is either correct or it’s re-requested, unless the buffer is too small or network latency is extreme, where you could have dropouts.  Audio file protocols are also robust with similar redundancy checks.  Therefore, audio files are bit perfect on properly designed streamers and DACs on a functioning network due to Ethernet protocols and industry digital music file protocols.
 

The Ethernet assures accurate data packs not timing that you are discussing, unless, as I stated before, the electrical signal over Ethernet carries RF coupled to the streamer or DAC click, where clock function is affected.  Timing from an audiophile perspective is critical when the sequenced  bit perfect data packages are converted to analogue.  So the Ethernet has assured the streamer or DAC has received a bit perfect file in sequence.  The conversion of the sequence is to be at standard timing (44.1, 96 KHz as an example).  The clock assures the standard file timing is accurate at conversion.   If there are timing errors in the digital data packages the resulting analogue voltage steps can jitter, which can introduce noise in the analog waveform. That jitter, in turn, can raise the perceived noise floor, blur subtle details, and reduce soundstage precision.  You experienced better timing is directly proportional to sound quality when you added the external clock.  My experience was different.   The $500 audiophile Ethernet cable was from a very respectable audiophile cable designer/manufacturer.   However, its metal connector housing was coupling RF.   The well designed cheaper cable produced improved SQ because it better insulated RF.  
 

in conclusion:

1. The Ethernet can send corrupted data packages
2. The redundancy in the Ethernet protocols assure data package correction and bit perfect data at the user level if the network connection is sound.  
3. The Ethernet protocols assure correct data sequencing, but this is different from audiophile timing concerns. 
4. Digital music file protocols assure bit perfect music files are timed properly at conversion to analogue.  
5. Therefore, the Ethernet cable does not affect jitter directly.   The way the Ethernet cable can affect jitter is if it is improperly shielded and permits RF coupling affecting clock performance. 
6. Ethernet cables can affect sound quality simply due to physics.  The degree of the effect and the benefit / cost ratio of expensive cables can continue ad nauseam.

Interesting exchange.  Thanks.  Have a phenomenal day and listening experience

I agree 100% with your post. 

Thanks.

So not to derail, but what about other digital cables then?   Spdif, AES, USB?   I have not deep dived the Ethernet cable rabbit hole, so I can't speak to that.  I use Supra 8 in my studio because it was recommended to be a solid cable and wasn't insanely expensive.  And I use a BJ cable in my other system.  But I have noticed a pretty massive difference between different spdif and USB cables.  Many people argue the same things for those - that it's all 1s and 0s it can't matter.  Clearly it does though as a kimber d60 clearly outperforms the BJC I had before.  And each tier of Shunyata USB gave me improvements from my PC to my RME interface.  All of this is to say, just listen to your system and use your ears.  Swap cables back and forth several times.  Make note of what you're hearing and then see if it's repeatable. 

Also side thought - make sure all power cables are away from other cabling because this actually makes a giant difference on a revealing system.  Just spent some time reorganizing my cables and it made a substantial difference on my secondary system!

Not only does the Omega X Ethernet cable in my system sound much better than any other Ethernet cable I have tried, but making changes up the chain make differences as well. I have google fiber to the house, but it converts to copper when I can get access to it. The ethernet cable that connects the modem to my fiber converter makes a difference as well. Follow this; the google fiber comes in the utility room. I connect an ethernet cable between the google box and my fiber converter. From my fiber converter I run fiber across the basement and into an audiophile switch. An Omega X cable runs from that switch to my streamer. I'm saying that not only does the Omega X cable sounds great/different from basic cable, I'm saying the first ethernet cable that runs between the google fiber box to the first fiber converter makes a sonic change. I don't understand it but it does.

Fiber transceivers make a difference as well. Try a set of cheap transceivers and then swap in a pair of single mode, duplex, Optospan transceivers and you will hear a difference. My friend says he understands that Corning fiber is preferred by many who have tried different brands. I had no problem believing that noise travels along an ethernet cable. This happens regardless of the ones and zeros traveling along the cable in an undisturbed manner, but the cable itself is passing noise to the streamer circuits. That said, I cannot understand how changes before a fiber run, or changes in transceivers can change sound, but I can hear it. I don't know If I can hear these changes in my Arcam/Klipsch system in my garage, but I can hear them in my big system. I'm in KC so anyone who wants to hear these changes please PM me and I can have you over for a listen.

4 years ago I was experimenting with fiberoptic bridges like Etheregen. I was adding clocks, cables and linear power supplies. Adding a fiberoptic bridge, an LPS and clocking into a switch in one box is what all these expensive audiophile switches do now and cost  3 to 10K. You can see my comments on these efforts years ago right here in Audiogon's forum history. 

Can I hear heads exploding? Do you have to understand how/why a cable made with Rhodesian dog poop (for example) sounds great to be able to enjoy its sound? Many of these vendors offer 30 day return programs. Give some of these technology tweaks a try.

@jrareform 

I wouldn't mind answering you question. Would you like me to?

Or I can leave it to someone else. At any rate, let's not get in to a pointless battle. You can take what I say at face value or choose to ignore it. Up to you.
