What I did first was to put ferrites on every connection going into the router and from broadband modem.

There is no voodoo in an isolation transformer. I would put it as a firewall on every connection not audio where you could use ferrites as a cheaper solution. But I'm actually abit intrigued, I read up on "medical-grade" LAN isolation transformers before but never got around to trying one.

What did have a good effect in my system lowering noise and edginess was exchanging all PSU's related to Gbit-switch/router network and Sooloos MC200 to higher quality ones from Teddy Pardo. That can be heard immediately not a "maybe" like with ferrites.
