The problem in "generic"/consumer-grade/IT-type cheap Ethernet switches are 1) they also have cheap (i.e., poor) clocks which are responsible for clock phase noise, 2) they use switch-mode power supplies, which are noisy as all get-out, 3) are not galvanically isolated and 4) said SMPS pass low- and high-impedance leakage currents down Ethernet cables, into network bridges/streamers, and ultimately, DACs, increasing jitter and creating timing problems. Even a fiber-based Ethernet switch will pass clock phase noise from its el-cheapo clock. Come to think of it, 5) they probably suffer from "common noise" problems, as well.
Oh, and the DC cables to the el cheapo SMPS' use cause problems, too, unless they are very short, use a JSSG shield, and are configured in a star-quad configuration using solid copper wire.
