How upgrades / your components effects different genre of music has interested me for a few decades. I used to have three or four disks I would take to auditioning sessions, influencing my purchasing. I noticed over time that while that music was sounding better, other genera at home would not sound as good. At the time I was really into electronic. The lightbulb went on… this is not a good ruler, electronic is fabricated and I am making it sound good to,me, not necessarily what the author intended. I listen to all music types, not just electronic..
Over time I realized the only music I could really use as a standard was acoustical. That I would have to hear it live and take recordings in to audition equipment that were the same. Quite abruptly the direction of my system changed… away from planar speakers and massive amps to tubes and dynamic speakers. All genre of music improved with each purchase. Season tickets to the symphony really sealed the deal and over a few years I had the best sounding system.
Now, that is not the only way to go. If you primarily like rock, then there is a know collection of stuff to optimize it. McIntosh electronics and B&W speakers sound exceptional with rock. But not as much with some other genre. JBL another speaker well suited for rock.
So the choice is yours. It is a lot of work to correctly improve the sound of all genre. But if that is your goal then tune your ears to acoustic music and evaluate systems based on it. Then you will most likely to be heading in the right direction.
