@drlou77 I run EERO mesh. I clearly hear differences between Ethernet cables connecting the access point to my streamer. I don’t use a switch.
My approach is to use a decent Ethernet cable (currently using Purist Audio) and worry about components and speakers first. When I’m sitting here scratching my head about future upgrades to components, speakers and cables, and there’s nowhere to go in that space, I’d play with audiophile switches.
In the post above by @txp1 , I respect his choices but we can debate what would be a bigger ROI, Qutest being a centerpiece with all the attachments to it, or having a clean DAC only approach with Chord DAVE, Tambaqui Mola Mola or some other high end DAC without all the accessories and clutter around the Qutest.
As i said I respect choices made by others, but my approach is components first, accessories later. Right, wrong or different, that’s how I tackle it.
