uglijimus, thank you *so* much for this resource - particularly the link provided to the audiocheck site. While I've previously done my EQing by ear, I really appreciate being able to find something that I can use to semi-quantitavely match with my ears and speakers.
I think you're right in that EQing can really help people enjoy their music. However, I think a lot of the audiophile objection to EQing comes not from the fact that it isn't what the musician intended.
I mean, after all - let's face it: there's no way to hear what the musician intended without having the exact same studio monitors, setup, positioning, ears and brain chemistry of the recording artist. While he/she's mastering the track, the studio is going to have no idea what the strength and weaknesses of your equipment are. And that's assuming the mastering artist is even competent, and isn't compressing the dynamic range within an inch of its life because, hey, who's going to notice on their Apple earbuds?
I suppose in an ideal world everyone would have reference grade equipment and their own personal sound engineer to master tracks to their personal taste. For the real world, with consumer audio, the EQ is the closest you'll get.
I think the main objection comes from the fact that an EQ circuit, if implemented badly and coupled with bad hardware, has all kinds of other negative effects on the sound. I find this particularly on portable audio players. For instance on a lot of iPods I've tried, the bass boost EQ overwhelms the amp and causes distortion and clipping in bass. I've found that engaging the EQ on my own little Sony can help overcome weaknesses in headphones, but still the EQ circuit has a subtle negative effect of recessing mids a little and diminishing dynamic range a little.
So often I've had to compromise in one way or the other. But you are absolutely right- when used wisely, EQing is terrifically helpful. So thanks for campaigning for it!
