Pimping your router


1. Use a wired router only
2. If wireless router is needed, separate router for wifi
3. only streamer, NOTHING ELSE connected 
4. use LPS to feed router
5. use shortest possible quality cable to streamer
6. use Acoustic Revive RLT-1 filter on spare router or streamer port
7. wrap router and LPS in EMI/RFI shielding material
8. use EMO EN70-HD filter near streamer for ethernet connection
9. use quality shielded cable between router and internet access point

All of these will individually improve your streaming SQ, in aggregate the effect is significant

As stated, I do connect via Ethernet as the Lumin doesn’t have WiFi and checking with the factory about galvanic isolation.
Sorry, I had understood that you connect the Lumin to the Actiontec  via ethernet rather than directly to the router. In that case a direct ethernet link to the router would be preferable.
Placed my router onto a Vibration Platform for microscope 

Got a faster & sharper pic on my iMac ...
I did check with Lumin who confirmed that the Ethernet connection has galvanic isolation.
That equally applies to my Innuos Zenith Mk3. Nevertheless inserting the EMO isolator with a short Meicord Opal made a significant improvement. Not obvious, I agree...
