Earning Power has nothing whatsoever to do with listening to music via electronic devices.
My experiences to date are there is very very little snobbery to be found in music replays as a Hobby, there is not agenda to keep the Riff Raff out, no exclusivity for the membership. That is not saying there is not individuals who share their interest similar in this Hobby who are not snobs, some of these individuals most likely are members within a forum, and some may even be frequent posters on their chosen forum/forums.
A Hobby and the attention it can generate through the usage of surrounding supporting networks, takes all sorts to assist with the cultivating the growth. I am not prejudiced towards any sharing their interest.
It is well noted on this forum and many others, exceptional listening experiences are able to be produced using electronic devices that are not stupid expensive.
As mentioned in a previous post, there are today in use numerous sources, the individual is more defined today by their choice of Source and Medium used, than their chosen music genre.
Years ago when in discussion you were Wed to a Vinyl or CD Source / Vinyl CD Source, with a specific liking for a Genre/ Multiple Genre's.
Today an individual is a Data Streamer, Digital Recorded File user, Phone user , Hard Drive user , CD user , Analogue Tape user , Vinyl user or any combination.
Even a typical found in the home Desktop PC or Laptop are considered today a replay Source worthwhile using for Stored Digital Recordings or Streamed Data Recordings.
Any will be considered Audiophile in relation to the end sound that can be produced, to achieve an End Sound that is deemed attractive does not require silly monies to achieve.
