Anyone using a LAN isolator?


For those running an Ethernet cable to their streaming solution, whether Raspberry pi, nuc, streamer, etc, anyone using a LAN isolator? If so, what are the benefits and which one are you using?

I use an ENO ethernet filter, passive, from Network Acoustics. It is wonderful.

I'm using an UpTone Audio Ether Regen with an After Dark Emperor Clock.  Sounds great to me.  I heard a definite improvement in the microdynamics and imaging of my favorite recordings since adding these two items.  Music became a bit fuller, more detailed and believable.

Are there other passive options for LAN isolation that are still effective at reducing noise?
