We cannot simulate all scenarios but so far it appears that what happens before the router is much less relevant then what happens after. For example we have ran a lot of experiments over time using a "cheap" readily available (although even these are now suffering from the supply chain issues) Ubiquiti Amplifi HD router. We have used them at shows, like in all 3 rooms at the Munich show, and in several home network situations, they create a very similar repeatable sound quality and/or signature in every situation. Now you can do better then this, and some home networks do perform better, so does our company network here in Oldenzaal made up of higher grade Ubiquiti components, and obviously the components we have under development, but nevertheless, the Ubiquiti Amplify HD router creates a pretty reliable repeatable result. No need for VLANs either. Naturally there's a philosophy in all of this, which includes network interface cards, switch, router and even software configurations, so yes you could say there will be synergy.
