As I "think" I understand it, the switch has transformers between each port to better isolate the signals.

But, I'm not a network engineer.

The difference between one switch and another is related to the common mode noise generated by each switch and each power supply. Some switches are quite noisy internally, while others do a better job of producing a clean signal. On top of that the associated power supply's noise injected into the switch can make a difference.

Frankly, I didn't really buy any of this. I just tried it because it was inexpensive and I was really surprised by the result. I didn't test a bunch of these I just went by the tests from Alpha Audio and other people's comments on various forums.

Here's a link to the Alpha Audio listening test - there are other videos where they test the noise output of the switches but I found this one the most interesting (though it's very long).
