I own a pair of Denon D600's connected via the long 3m cable into a FIIO E12 (with Bass Boost enabled) connected to a SanDisk Zip Clip running the latest version of Rockbox.
Using a sine-wave mp3, I've tried to equalise the D600's by ear both on the Clip & an IPhone 4S using the Denon Music App.
When I've made the necessary EQ Cuts & Boosts to make the sine-wave sound the same volume through the frequencies, I end up with an EQ profile similar to the above D600 profile (except for the compensation of the E12 Bass Boost.)
However the results on either setup sounds awful or muddy.
In the end I had to make an improvised EQ setup by ear, experimenting & googling as I went along.
I ended up with the traditional V profile of raised Bass & raised Treble with perhaps louder vocals:
eq enabled: on
eq precut: 75
eq low shelf filter: 32, 7, 50
eq peak filter 1: 64, 10, 30
eq peak filter 2: 125, 10, 30
eq peak filter 3: 250, 10, 30
eq peak filter 4: 500, 10, 20
eq peak filter 5: 1000, 10, 15
eq peak filter 6: 2000, 10, 30
eq peak filter 7: 4000, 10, 55
eq peak filter 8: 8000, 10, 60
eq high shelf filter: 16000, 7, 75
This is the best sounding I've got it so far.
Is this correct & does anyone have any suggestions to improve?
