My findings are that the general characteristics of the gains heard in a Speakerlink application are faithfully carried over into Ethernet applications where TCPIP is in play.Dave
And there are many here who have likewise experimented with alleged 'better quality' Ethernet cabling and found zero differences... always assuming that Shielded and Screened Cables are used... and that all streaming audio components are on a dedicated switch to avoid impact [RFI/EMI] from other activities elsewhere on the network
In the presence of TCPIP, this may seem mad, bonkers and slightly frightening, but it's very true, and there is plenty of quite basic science to support the finding.
"Science" involves the process of "Peer Reviewing"... so if you could please point at any Peer Reviewed & Independent articles which claim that 'better' Ethernet cables improve the Ethernet data transmission itself??
It's generally accepted that RFI/EMI migration to the DAC is the only means by which Audio Quality can be impacted... a process that has nothing to do with the efficacy of Ethernet and TCP/IP transmission.
And RFI/EMI mitigation is something that can quite easily and cheaply be achieved rather than spending unnecessarily large amounts amounts of money on Ethernet cables for which there is simply zero Peer Reviewing available.
The 'transmission' of Audio Data via Analog, SPDIF and AES / EBU methods ALL can benefit [to varying degrees] from properly constructed cables [i.e. properly constructed and high retail prices are not always the same thing]... but audio data transfer by Ethernet Packets and IP addressing is a different matter.
