Mogami is a popular brand for pros as much because it is durable when physically abused as because of any possible sound difference. The microphone cables (remember those?) that were used to swing microphones like a lasso have more to endure than the zip cord that sits sandwiched between an area rug and wall-to-wall carpet in my music room.
Pros usually have to buy large amounts of cables. Mogami cables are expensive if you need to buy hundreds of feet of it. Home audio users are only buying short lengths. Mogami cables are cheap at home audio lengths. The lengths of cables for home audio users are usually short enough it doesn't cost much to buy the more durable professional or touring cables which should last almost forever.
Mogami is popular because they work like intended, neutral in sound, very durable and very flexible for a reasonable price if you buy in big bulks (like music studio's tend to do). Most pro audio studio's i know make their own cabling with Mogami cables and Neutrik or Switchcraft connectors and patchbays. All is custom made mostly, by the people who iinstall the studio gear also. It's like a standard practice to do almost, where most even don't think about alternatives.
Mostly Mogami cables on my hifi. It is delightfully supple.
Think it was more an example of a brand name that makes sense....vs the charlatans like Fraudioquest, Nordost, Transparent, MIT, SR, etc.
