Apologies for the lack of updates. We‘ve been absolutely flooded with enquiries the past few days. Replies to e-mails may come with a 24-48 hour delay but we hope to be able to fully catch up over the weekend.
@Christiaan Punter is putting information packages together to be published soon.
I understand it may all look very complicated.
1) The switch + network card package turns a very noisy rj45 interface into a very quiet SFP interface. This combination also offloads some network processing from the server to the switch reducing internal processing noise. This alone improves Roon playback performance to above what you‘ve been reading as feedback from the 100 or so XDMS alpha testers. Naturally XDMS benefits too and remains the current Taiko SQ SOTA.
2) The router allows full control over the datastream being delivered to the Switch/Extreme. It can define all networking parameters and controls the actual amount and flow of data present on the network. It also allows controlling a wi-fi accesspoint to control wireless networking parameters. Whether or not you replace your internet modem is actually not that important, it will achieve what we want to do regardless. However less is more, it supports a lot and if it can replace your ISP provided device, why not. It has 5 network ports and can therefor create 5 separated networks.
In short:
1) The Switch / network card combo reduces noise by offloading (moving) processing from the Extreme to the Switch.
2) The Router reduces noise by controlling the actual DATA on the network leading to another significant lowering of noise.
