I dont' know how many dB's they squeezed out of it but it has to be a lot. Listen to something like the drums at the start of Aenima (the track) and hear how much space there is?? I don't know if maybe like was said at the start they were sidechaining everything to the kick w/ a comp and maybe limiter, but stuff like Tick and Leetches and Triad sound too thumpy and not "wide-open" enough...there's no spatial image to me.
