For when you hate all the noise your router is causing in your streaming device due to all the noise being passed through the network cable :).

It seems to be the same technology ?

Haenk:
"galvanically-isolated inputs to reduce digital jitter and overall system noise.

The LAN iSilencer boasts premium galvanic isolation technology, where electrical circuits are separated to eliminate stray currents. Audio signals can pass between galvanically isolated circuits to block differences in ground potential or currents induced by AC power."

Oh well. How will a transformer in a network device reduce digital jitter? And what audio signals are they talking about? There are only some Ethernet packages - which happen to contain encapsuled, encoded data, which might be or not be part of a digital audio stream/file.

I can only see a benefit in avoiding ground loops, if the shield is not connected. But they are not even talking about this?!?

Daixiwen:
Ethernet is already galvanically isolated so all what that thing does is to add an extra transformer in series

xrunner:
Only $89? They must be new to the audiophool market with such a low price. Raise it to at least $500.
