You named some stuff in my personal collection, and I have Classic Audio Loudspeakers in my living room. They can shake the walls! What's nice about them is that you can play sustained high levels without compression and without straining the amp.
More: In Flames, Skepticism, Therion, Earth, Sunn (and incarnations thereof), Om, Opeth... I don't think anyone would be suggesting that a speaker is good for some metal and not other forms of metal.
Really, all music is composed of combinations of sine waves and transients. Its been shown mathematically that nearly all waveforms can be created by the right combination of sine waves. Its only the human ear/brain system that makes the distinction between various forms of music. The reproducers don't care so long as you stay within their range of linearity. So dynamic range is important, but on this matter metal rarely has the dynamic range of classical, and with peaks of 120 db on stage, classical can be just as loud although usually not at sustained levels.
I'm not sure what you were implying about digitally recorded, but FWIW, when analog technology is used you often get greater dynamic range. This is not because analog as more dynamic range (although it is so close its really not worth arguing about) its because digital recordings tend to have more compression because that is how the industry likes to handle it. Analog is a little more forgiving of overload and so while compression is still likely, its often just not as much.
I run an LP mastering operation and a recording studio BTW, so I see this stuff first-hand.
