riccitone - haven’t tried many switches but did try two different Cisco switches: 2960 & Meraki.
Alpha Audio has done a lot of tests on various models (via YouTube) in great detail but they go the copper (ethernet) way and not optical fiber.
I had tried it their way too and the improvement wasn’t in the same ballpark as fiber. They indicate there are differences in the switches and categorize them overall as small. They do break it down among many different options including some of the commercial audio switches which don’t all get high grades.
From my Verizon fiber connection, I’m continuing that rout with cascading Cisco and upgraded Finisar transceivers.
