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?

Would anyone work on the engine and transmission of a high performance automobile like a Ferrari if all four of the tires were almost flat? I think of correcting a hearing loss much the way I see the inflation of tires on a high performance race car. One really cannot move forward without the removal of some simple, basic obstacles to high performance.
A friend with severe hearing loss got some newer hi-tech digital hearing aids, bought a new Naim Supernait 2 and hasn’t looked back. Loves it. 
M brother got hearing aids last year but takes them out when listening to his system.His aids enhance the frequencies surrounding the human voice which makes for a bright fatiguing experience when listening to music.He said walking through crackling leaves last fall was excruciating:)
Leave your hearing alone, it appears to be good enough, you don't need any aid. Upgrade your system, whatever you feel necessary.
