I need to follow up on my earlier post about the 30 being a metal genre monster. I've been logging some serious time with it and my old thrash favs Kreator, Overkill, Dust Bolt, and Exodus. There's just enough meat on the bone for darker, meatier sounding bands like Exodus. Bass blasts and those riffs explode with power and presence. The screechy vocals are intense but manage to stay just south of harsh. And guitar solos are crystal clear and pure energy on the 30. The only issue that pops up from time to time is some of these old albums are mastered on the thin and bright side, and the 30 does nothing to temper it.
My other metal favorite, the Atticus, is much much better at tempering brightness, and adding a nice sense of weight to recordings that lack it. But it also can sound a bit boring at times with some of the more well recorded albums. Good example is Overkill's "The Electric Age" album. This is a very well recorded album (from a metal genre standpoint!), with decent dynamics, warmth, and clarity. The 30 makes this album sound visceral and powerful. Blaze's shrieks grab your attention without offending. Riffs have reasonable weight and heft to sound "crunchy" (metalheads will know what that means!), with lots of energy and emotion. On a macro level listening to this album on the 30 makes me start bobbing my head hard. Hard enough to almost send the headphones flying off my head more than once!
I found myself constantly stopping working and being swept up by the raw power and ferocity of the metal. The best metal makes me feel like a live power line was shoved up my butt, and this was the case with the aforementioned combo. I sat there listening while feeling so overcharged and energized I seriously wanted to run full speed head first into a wall while screaming at the top of my lungs. Ah, my beloved metal, how you calm the savage beast within! haha I know, that all sounds silly, but I seriously lost way too many hours of work to blaring guitar solos and shrieking vocals. The Atticus sadly doesn't bring me to such highs with the same music. At least not without changing pads and running it on solid state to brighten it up significantly.
So what's my point? Over time my opinion has only solidified, the 30 is indeed a metal genre monster in the best ways possible. Oh, and the 30/Vali 2 combo rocks!!!!
