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

I don't get the point of the question. Are you suggesting a different recording method was used that gets away from the norm? Sure it's nothing like free form Jazz scales, but get down to the nitty gritty and they all start with the same basic recording techniques. Some studios are better equipped than others, but then everything sounds the best it can with high end equipment.

My personal experience says yes, but than I think any music benefits from a good system.

i got Shake Your Money Maker cranked up a bit on my mid fi system with just 1.2 KW a side…..sounds great……

whaaaaaat did you say ?

War Pigs is a great HM song to test a hi-fi system. 

Heavy Metal only benefits from an extended power outage.
