Please don't encourage them into the hobby. My time listening to music is first the thorough enjoyment of the music and the very close second is not having to be in the room with my wife. My wife could not tell the difference between am radio and my reference system. Same way she cant tell the difference between 4k, 1080p, or analog tube tv. Some have and some will tell me she can but she doesn't care. I will challenge you on that maybe, as soon as i find something she does care about other than bitching every second.
