Network Acoustics Eno Streaming System vs SGC Optical Isolation System

“I don’t have a noise issue”

It will be interesting to hear your feedback once you remove everything in the path and go direct from your modem or router to your Innuos. I know this is A/B is bit of pain but this is the only way to re-evaluate what each of the devices in the signal path doing to enhance your listening.

Optical comes in number of flavors, hearing one or two implementations may not tell the whole story. I've had generic with smps, generic with one lps, generic with two lps, OpticalRendu with generic, OpticalRendu with OpticalModule. I've also used optical both pre and post server or streamer, optical with both switch plus router or router alone. Finally, tried various power cords and lps with the above.

I have Finisar industrial grade optical transceivers coming in Friday along with a custom build optical cable (lowered reflectivity) from AfterDark. These transceivers have lowered jitter vs all other transceivers. So I shall soon have the chance to hear most optimized optical I'm aware of sometime in coming week.

Also further experiments coming via upgraded ISP speed, 600mbps vs 300, already ordered. This along with even better Netgear router, with lower ping time and much better latency, meaning lower jitter than present Netgear. The new Netgear will also have all wifi turned off, assigned IP address to present Netgear which will then provide wifi for everything with exception of streaming chain and NAS. Wifi nasties, meaning RFI will then be segregated and much  further away from my audio system.

Only variable at a time with above so this will take a bit of time to evaluate.

A simpler solution, which doesn't add more noisy power supplies is this one.  Galvanically isolated and 4k V breakthrough voltage:

Well I am tickled pink with adding a filter going into the "Generic"  10Gtek Modules. I also have a .5m FO cable now. 

Funny thing is these modules are all the same the real upgrade on the FO side would be cable and transceivers like @sns said. Also upgraded my ethernet switch to a   NETGEAR 5-Port Gigabit Ethernet Plus Switch (GS105Ev2) - Managed. The boys at Alpha Audio found this to be one of the better switches in their shootout: 

All for under $250.00 and I am good to go for now.

@sns 

Is your Netgear a modem/router combo unit or is it a stand alone router? Is it in close proximity to your server/streaner or distant and remote. Location?
