Should I upgrade my system while losing my hearing?


WOW!!! My system sounds great. Wifey says it sounds great & leave it alone. Yet I believe I know the weak spot in my system and I want to upgrade it (Tonearm). Yet some would say that my amp is weak. Its just a VTA Dynaco ST-70. But Lordy, does it sound good. Even so, I'll probably replace it because the power switch is on the back which makes it hard to get to turn it on *& off.. But then I think of my age (68) in 2 months and my hearing loss and I ask,   does it make sense to upgrade? Should I really spend thousands of $$$$$$ to get a 3-8% improvement? But who's to say it won't be 20%..........25%? And with my hearing loss, will I be able to hear it? I hear music pretty good. Its conversation I don't hear. But I've heard enough conversations , etc anyway. 
I often think about my old step father who often said, "There ain't no fool like an old fool". I think I understand what he meant.. AWW I'm gonna do what I want anyway. Just making conversation. But does it make sense to upgrade my system? Or get hearing aids? Ain't gettin' old fun?

FWIW the hearing loss is a relatively new thing.I had a hearing test 10-12 yrs ago and was in the normal range.  I only recently noticed that I can't hear the conversation on TV as well as I used to do. And yes, I will take care of it.. .....though I wish I could put that hearing aid $$$ into a tonearm.............or .........
Digital hearing aids suck. Better to listen without aids and equalize the system to compensate for your loss.

The music sounds fine to me. I know about the hearing loss only from TV conversations which I cannot understand.
Fortunately I don’t know much about hearing loss firsthand but it seems like I’d want the range of sounds that my ears are capable of processing to sound the best. Listen to upgraded equipment and if it doesn't sound better then don't invest more. I know that sounds overly simplified but I’m a simple guy.

I had hearing loss during my time with Air Defense Artillery (Hawk missles) and Field Artillery (Howitzer) units with US Army and Army Reserves. Lucky for me after I retired I was able to get a partial disability and the VA pays for my hearing aids. Yes (maybe like you) I cannot hear well during crowded places when someone is talking to me. I disagree with some audiophiles here who think you should not get hearing aids. It’s your choice, for certain, but for me I think the new hearing aids are much better and they can potentially not only make your music listening experience better, but your life more fulfilled. I have Resound brand and they can be adjusted on my smartphone.
