No they don't in this system. TCP packets have checksums. That checksum allows the TCP layer in the operating system to detect bit errors. If that happens, it discards the packet and the sender will retransmit it. So unless the link is broken solid in which case you get a glitch or playback stops, you are good on bit errors.
The player software and DAC are downstream of the above. They have no ability to see or know about packet bit errors. They either get reliable bits or nothing.
Now if there is noise that is riding on Ethernet connection that gets coupled to an internal DAC in a streamer, then it could cause jitter and other distortions. The measurements provided before in that test fixture shows that such noise does not bleed. Of course broader tests are necessary to make sure that test was representative.
Oh, you misunderstood my meaning. I'm well aware its a data cable incidentally.
Yes, thank you -- I may be conflating audio cable with data cableLet me know if I answered the question adequately .
Are you postulating there could be 2nd order effects of differing nature based on the Ethernet cable used?
That's my conjecture, yes. No need to postulate data differences, just as for S/PDIF and USB cables. Amir makes the point in his post about noise, that's what I was referring to by '2nd order effects'. Any clearer now?
Seriously??I didn't hear a difference between Audioquest Diamond and Generic $6 cable that was provided by the manufacturer!
Can you tell us the nature of that improvement? Can it be reliably demonstrated or measured?Ethernet cable upgrade even to 60$ cinnamon has dramatically improved my streaming quality.
Still feel that way? The only conclusion I can draw is your streamer's dac has a very well shielded clock and well isolated ground plane.
They always say the last meter is the most important, antennae effect for noise. On this forum 60$ let alone 1k for a Sigma is hardly considered expensive. Really worth your time to try. I was floored.The infrastructure in my room has been well sorted out. Great shielding, electrical and isolation, makes using expensive Ethernet cable, a waste of money.
Hi KalCan you tell us the nature of that improvement? Can it be reliably demonstrated or measured?
So far I'm only aware of 6 people that can hear a difference in Ethernet cables. You aren't one of them (neither am I apparently)
Should just try it... it’s fairly easy to discern.I haven’t tried any audio Ethernet cables, Trying to keep an open mind about it... but I was an engineer for IBM during the Token Ring Lan days and our testing/certification with TR and Ethernet in wiring closets never indicated interference or packet loss during close proximity testing or max runs between CAU and MAU units and Eth repeaters under heavy traffic conditions. We used scope and packet analysis to determine any crosstalk or saturation issues Affecting data.. CRC and netlayer hardware protocol error checking we’re also monitored. UTP is all we used on the Ethernet. we were testing random data , not music.. but we found no issues in close contact conduits for max length runs.
I doubt that shielded UTP or better conductors would have made any difference as we saw no issues in our testing.. FWIW, YMMY.
We joked that gold wire might show higher bank balances if used... but 1’s and 0’s still would look the same..
Should just try it... it’s fairly easy to discern.
Listening is always the best way to discover these things. It’s always about our own contexts.I plan on it.. I recently went Thunderbolt 2 to Ethernet, where I was using a USB 3 to Ethernet, using Clamshell mode to reduce EMI.. Things I never gave a second thought to before visiting these forums..
still in Progress..
