As an audiophile and music lover the only equipment that you need to be most careful about are “the ears”. Hearing loss with age is natural, especially in the higher frequency regions of the sound spectrum. If you have been constantly exposed to loud music playback via a personal music device/headphones or at concerts, the damage could be more!
Practice listening at safe volume levels and remember that the greatest audio gear in the world is the human ear and our ability to hear! Recommended reading: The Universal Sense by Seth Horowitz.
