Does Heavy Metal music benefit from a high end audio system?

Great post! I am a R&R lifer. Also a musician until I was 35. I purchased Electric Ladyland the day it was released, same with his other albums. Same with Blue Cheer, all Zep, Black Sabbath... Like many of you. 
The difference is although I still purchase all those remasters. But I kept looking forward. 
I too ended up (like a drug addict) to want more, deeper, more complex, challenging music. Many have been mentioned here for the daring....
I offer the 2019 Grammy winning song for Best Metal Performance.....

My personal Best Alternative Metal album for 2021..... ERRA (Self Title.)

I think it takes a certain personality trait to prefer metal (same as with any genre), but I think Tool is one of those transition bands that people can dip their toes in to find out. They live on the border of hard rock and metal, their albums have some of the best sound quality of any hard rock/metal (but are sometimes a little "weird") and they are not overwhelming (too fast).

I'm not a huge "alternative" fan, but I like Erra. They immediately reminded me of two albums in my library, although these albums lean more toward heavy than as alternative as Erra. They are Divinity - The Singularity (try song, Lay In The Bed You Made for that alternative flavor)  and Beyond The Fall - Antibody (mostly because of the similar vocals).

Like you, I wanted more complexity, but my "power inclination" always drives me to crave simple chugging. So I usually wind up liking a combination of the two. Especially complex songs with a brutally heavy breakdown. I play guitar (and some bass), so I understand how to rate the difficulty. I know a lot of people think metal is a lot of noise and screaming, but they are monumentally mistaken. I can play a lot of Van Halen, but I can't come anywhere close to the rhythm speed and tightness of Warfect's Fredrik Wester on the songs Drone Wars or Inflammatory, which BTW is on what I consider the best thrash album since the late 80's, Exoneration Denied.
