"you will never know how heavy metal recordings are suppose to sound unless you hear them on a good large scale system."
Yes, like, when we scale-up to stadium seating. I question how it is we expect to experience rock concert reproduction at home with any system. With resolving systems we can get close to jazz clubs, chamber music, some well-recorded 9th row symphonies, and of course, close-miked vocals mixed for the center, etc. But AC/DC in a 15 x 20 room, that is an actual shared space with other humans? Not to mention innocent bystanders up and down the neighborhood. "Large scale" reproduction enough to hear resolute sound from that band or any band like it can be done, yes. On a space station.
