I love how John Williams, a brilliant classical guitar player, said about guitar making, that "it's easy to build a classical guitar with rich bass, but it's hard to build one with rich highs". Nothing wrong with boom-in-your-face bass and drums, but of course to do that is easier than to do the opposite. Even I tend to boost the bass side too much in my little recordings and it always impresses me how delicate CA's mixes in that respect are.
