Instead of fretting over the possible shortcomings at both frequency extremes, may I suggest that you if you simplify and hone your focus on the VERY BEST midrange reproduction you can get ….. all good will be restored and angst relieved.That’s where 90% of the music spectrum resides.if you get the midrange right: “…all the king’s horses, and all the king’s men….”
ergo .,,, that is why I offloaded my honkin’ floorstanders and upgraded to HARBETH 30.2XD standmount speakers. My Yellow Brick Road to Audio OZ has now been restored without concern for any natural aging warts. In my experience, I love the music experience more now then with any speakers before.
I’m 69 years old and yes…l too endure that I am inescapably not as good as I once was in many ways; including natural aging induced hearing loss , (but I keep telling my wife that I am as good ONCE as I EVER was ….)
IMO, you are over thinking this , so don’t sweat the petty things and don’t pet the sweaty things. Enjoy!
Old Guys Rule ….. old age and treachery will overcome youth and enthusiasm!
