H8P is a lot more forward at lower-treble region (5000-7000 Hz), leading to a slightly recessed upper mid (2000-4000 Hz), while EM32 is much linear from 2000-9000 Hz to my ears, creating a more of a coherent sound, and presentation.
So which is more forward? depends on what you like. Generally speaking EM32 is more laid back, and H8P is more forward (specially string instruments). But for vocals, I would say EM32 is more evolving. Relatively speaking, H8P is shaper/edgier, but EM32 sounds like it has more grains.
In terms of power, EM32 > SE5 = H8P. But SE5 is really good at creating sub-bass impact~
