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

In general any genre will benefit from better system. What’s more interesting is the fact that Heavy Metal benefits more from solid state systems than from tubes. I have both kinds of systems and got proof of that fact many times. 

Yes, it will.

It’s the recording/pressing/mastering...more so than the system....some rock or heavy metal sounds like a congested mess on any system, Jmo and my ears....I do not listen much to it, and favor jazz, bluegrass, classical, and some country...mostly the older stuff. To me, this form of music is recorded better and also sounds better, even on a modest system. Also, to spend as much on a system as you would spend on a small home is just ridiculous, to gain maybe a fraction of better sound. 

Only if you can get the RATT out of it...

Hello,
I truly believe it does. The better the system the better the detail and separation. That’s easy to do with Jazz or Classical. Heavy metal need clean power. You will hear things you have never heard before while getting the Led out. If you don’t have a super resolved system go to a high end store and try it out.
