New speakers will sound better if you buy the right speaker - an upgrade. You will never be young again, but given your current hearing status, new speakers will sound better then your old speakers, and yes, I think you will hear the difference - i.e. what you can hear, will sound better.
Hearing problems and speaker upgrade
Like many 68 year olds I have developed hearing issues at the high end. My new hearing aids help in conversation but to me interfere with the sound of my system— highs are clearer maybe but sharp and shrill (plus it just makes sense to me that the hearing aid speakers aren’t as high quality as the speakers/system I’ve put together over the years). So I remove hearing aids when listening. So I’m wondering… is it worth it to upgrade my 40-year-old speakers? Will better speakers help get me back closer to what I was hearing before? Should I just accept the change in sound and adjust to it? Any insights appreciated! Thanks
