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

Much of the newer metal is recorded very well. Parkway Drive, Soulfly, Machine Head all have very well thought out and produced recordings. My system is extremely resolving and Incubus / Science sounds so good I listen to it often. Depending on what you consider metal, some of todays heavy music beats the pants off anything recorded 30 years ago. Listen to  Nothing but Thieves / Broken Machine and you can hear the possibilities for tonality and separation from todays metal.

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...
