Hi! I am wondering what characteristics in a speaker (or other component of a hifi) cause that one needs to stop listening music, apart of the high volume levels, of course. I experience with my present speakers (Magnat Motion, some low entry level hifi stuff) a sort of tiredness after a certain time listening to them, and I read that depending on your system, you get that very early, or later on. My personal feeling is to relate that sensation to brightness, but I don't know if that is right. I am very concerned about that because I very like Klipsch RF series speakers, and they are quite bright in the sound. I didn't listen to them for a long time, so I don't know if they'd cause that. Do you have any opinion to share about it? Thanks.
