Anyone using a LAN isolator?

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.

I have experimented quite a bit with LAN isolation. I am currently using two of these: https://ediscreation.com/product/silent-switch-ocxo/

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

@thyname - Where did you purchase your SILENT SWITCH OCXOs?  Did you find a seller in the in the USA or did you need to order them from Hong Kong/Asia?
