It looks like the big spend (besides avoiding Gigabit being a feature… wow) is the power supply being linear. Having taken scopes to power lines in homes, I can grudgingly attest to the non-zero impact switching power supplies have in audible frequencies.

But it’s comically small and solvable much more easily than spending this kind of coin.

I was expecting an AVB switch with locking connectors and redundant power. You know, like a pro audio mission-critical device. Instead it’s basically like using stacks of hundreds to vibration insulate your CD player. It might technically improve things, but the return on investment is poor.

I haven't used a scope, but I have had some laughs plugging things into the same circuit as high gain guitar equipment.

Yes please, let's amplify those audible frequencies to audible levels. A good PSU goes a long way.

By the way, if you are ever tempted to measure AC with an oscilloscope, please use differential probes to reduce the risk of damage/electrocution. It is very easy to create a pretty significant voltage potential across your probe and reference when poking around with high voltage.
