Since I started wearing hearing aids I appreciate music more. My deafness was brought on by measles as a child and so I have a characteristic lack of response over certain frequencies. I didn't know this until I was tested only recently. My hearing aids act as mini graphic equalisers in my ears as well as a general boost in hearing. Having said that I have never been one for top hi-fi gear, I guess because, without knowing why, I could never appreciate it fully.
