Headphoneus Supremus
Joe, I was thinking the same for different genres of music as I was even thinking that some headphone work better with wider genre vs other that are limited(and this is based on their FR, which is obvious), so why not have the source be changed accordingly to the type of genre of music which can be predicted to have heavily compressed output?
Correcting for lousy engineering is another thing altogether. EQ won't do everything. Dynamic expansion, filters to soften clipping, etc can help as far as they can. If I really liked the music, but the engineering sounded like a horse's hind end, I wouldn't buy headphones or amps that presented lousy engineering better, I'd probably just edit it in a sound program and bounce out a version with a band aid on it.
