I’m no spring chicken, and my hearing is around 14k, so I’m in the same boat I have tower speakers with built in sub woofers, plus two SVS Ultra 13 subs with the upgraded plate amps 1,200 watts, 4000+watts peak all controlled from my smartphone and using the SVS app I used DIRAC to dial everything in and just love the viseria impact! I drive my speakers with a very powerful D class amp I also have a tube amp and tube pre amp that I use along with my Magnepan 7’s You may also consider getting a streamer as you’ll discover so many new artists! Enjoy your search and if you end up with good towers, like Goldenear and two sub woofers, you’ll love it!!!
