Audio Grade Ethernet Cable

... Ask yourself why there are so many audiophile network devices out in marketplace. Some will claim snake oil ...

What I ask is this:

What is the advantage of locating your network components physically close to your audio system?

Part of the problem is that many people have very poorly configured networks. Many still use their ISP’s modem and router. Many cram these low-quality devices into their equipment rack, or place them nearby. So they are looking for ways to remedy the noise that results, when they might get equal or better results by simply relocating their network equipment. Or, as others have noted, by simply upgrading the streamer.

... There are two approaches. Fix the network or get a better streamer ...

I don't see this as an either/or proposition. You can work to create a stable, quiet network - in part by physically locating network components distant from the audio system - and you can also use an audiophile quality streamer. I think both can contribute to better sound.

How does putting modem and router close to audio system pollute if wifi disabled?

Simple. Modems, routers, switchers are all potential sources of noise. Locating those devices distant from the audio system can reduce or eliminate that noise.

I suppose I understand the resistance to even trying this scheme, assumptions and presumptions are inherent to our species.

Asking questions and providing "resistance" are two different things. You seem unable to answer the question:

What is the advantage of locating your network components physically close to your audio system?

Please note that I understand your scheme works for you. I’m not questioning that - I'm only asking about its supposed benefits.

... how do we eliminate, or at least diminish this pollution source? We locate modem and router close to audio system ...

How does that diminish the "pollution source?" It only puts these noisy components closer to your audio system. 

... modem and router powered via lps ... disable wifi on router in order to eliminate contamination via rfi ...

You can just as easily implement those remedies while also keeping your network components distant from your audio system.

And that’s what I don’t understand: What is the advantage of locating your network components physically close to your audio system? The only benefit I can imagine is that it reduces the length of the one ethernet or fiber cable that connects to the streamer. Please tell me what I've overlooked.

It's always puzzled me why so many users cram their modems, routers, switchers, and various digital peripherals close to their system, then jump through multiple hoops to rid themselves of the noise that results. It's much easier to locate that gear distant from the system, and connect to it with only an ethernet (inherently balanced!) or fiber cable.
