I went through 2 CalDigit TS3 docks previously, and returned both of them. They had a good number of ports and seemed reliable for the few weeks I had them. But both of them had audibly noisy capacitors, resulting in a tinnitus-like 16KHz tone that would get louder when moving the mouse or when connecting an external monitor to the dock.

What did you replace it with? Having the same problem with mine and looking for an alternative.

We have three StarTech docks since November or December. No coil whine so far, except for the Realtek NIC (which works out-of-the-box on Macs, but is meh otherwise), we didn't have any issues with it.

I bought two identical 3x 4k docks from Startech, and used them for M1 and M1 Max macbooks. One of them developed a very loud coil whine. No other problems, but it was too loud to be used alongside a dead silent laptop. The other is fine.

Docks are always a hit or miss thing. I had Dell docks before, also ~350 eur or so, and they consistently failed to wake up the external screens on resume from sleep. Same screens worked just fine on the Startech.
