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.
Does Heavy Metal music benefit from a high end audio system?
Not to dig at the genre although I’m not a fan, does Heavy Metal music benefit from an higher resolution systems? I’m not talking about comparing to a cheap box store system, rather, would one benefit moving from an audiophile quality $5-10k to a $100k+system?
