Network Acoustics Eno Streaming System vs SGC Optical Isolation System

It seems like a more expensive GigaFOILv4 

@mitch2 no not at all the OPT bridge is fiber optic conversion/isolation. The Gigafoil is and expensive version of galvanic isolatior like the Ever Star products. 

No?

@amtprod 

Is it better to have both the cable modem and the wifi router as close to your equipment as possible, or should the two be separated some distance?

There is not a consensus regarding this. Some very knowledgeable audio streamers advocate close proximity to the audio system and others advocate remote separation.Both sides report excellent sonic outcomes. Once again, implementation is key.

The GigaFOILv4–INLINE is the newest generation of the FOIL™ brand of Ethernet filters. Based on patented Fiber Optic Isolation Link (“FOIL”) technology, the GigaFOILv4–INLINE utilizes fiber optics and specially designed circuitry to prevent 99.99999999% of electromagnetic interference (“EMI”) from passing through the filter. The filter covers a frequency range of below 14kHz to beyond 18GHz and does not require a passband, meaning the only signal passing through the filter is the clean digital Ethernet signal.

FOIL = Fiber Optic Isolation Link

Obviously the same number of LAN/ethernet cables so possibility of rfi entry through connectors exactly the same. The differences are more signal loss with long runs of ethernet vs coax, also best quality LAN/ethernet cable becomes affordable with close to system placement. Now if one doesn't believe ethernet cables sound different that doesn't matter. I and many others hear differences in ethernet cables so it matters to us.

Now I can see  a possible competitor to close modem/router setup in going to optical conversion close to modem/router, long optical better than long ethernet. This issue then becomes all the peripherals, therefore, lps, power cables, power conditioning used with modem/router. I've found quality of AC/DC cables, LPS, and power conditioning to affect sound quality. With close to audio system setup I can use my already installed dedicated power lines, power conditioner, also running network components on separate AC lines may promote noise from ground loops, generally we want all components  in audio system to be on same circuit, less noise with grounding potential differences. I've tried modems/routers and/or LPS on different AC lines, diminished sound quality, although this could have been attributed to other variables.

Nope close modem/router is best and not that costly to implement. Two options here, DIY or technician runs long coax to listening room or have ISP  entry to listening room. In either case wifi can be run from second router connected to unmanaged or managed router, that router can be placed in best location for whole house wifi, this means no wifi/rfi noise on audio system network. So add up advantages, shorter higher quality LAN cables, less signal loss LAN vs Coax, ability to use same AC circuit for network, no chance for AC ground loops, finally best quality power conditioning via audio system PC.
