Perhaps we should take the HP discussion further in another thread (as is the planar speaker bit ?) but in my quest for the ultimate headphone for me I did (beside a lot of auditioning what was possible) also much comparative research on graphs (as they tell a lot but not everything)
Here are some graphs that might interest you (and others):
some cans where I drew the 'should follow the ideal line' in.
Note the ideal line is gradually sloping and NOT horizontal.
This has to do with the fact that there is no room and no distance between the reproducing medium (loudspeakers) which alter the sonic signature.
Try listening up close to speakers and you'll understand what I mean.
The treble is more prominent and bass is less present.
Headphones use the same electric signal so would have to be compensated for this which every manufacturer does.
Also the bass impact on the body is not present which is compensated by some lift too.
Ever tried to listen to nearfield monitors (the kind used in studio's) in a livingroom ?
These nearfield monitors are 'adjusted' to simulate the distance you would get in a listening room and sound a bit dull in a living room.
HD800 vs veil lifter modded HD650 (approximated from original HD650 graph, not actually measrued)
Denon D-7000 vs HD681 without filter and with (more severe then 2nd ed. filter).
The HD681 did sound too dark and dull with this filter.
What is visible from this graph, if you interpolate between the 2 HD681 graphs) is the resemblans in the lows following the ideal line in the graphs above
The D7000 does follow it pretty well, no doubt why headphone.com was raving about it before the HD800 arrived.
HD800 vs DT770 with and without highs filter
Iater I also stuffed the cups with wool to damp the resonating of the bass which would lower the left part of the graph and uses it with the dedicated filter.
Still was not my ideal can and started sounding to 'dry' after the wool thing.
Never got it absolutely right.
I listened to all my cans on a good amp with 10 Ohm and 120 Ohm outputs b.t.w.
HD650 vs HD681 (with the first filter published in the Grotto)
Here you can clearly see the difference in low reproduction and the different hump I was talking about.
Here you can download some interesting graphs taken from a Japanese site.
And yes.. some graphs did vary from those from headphone.com also note the dB range on the left which appear to make the graphs 'flatter'

I'm done now I think...
Sorry for hyjacking the thread by not mentioning the LCD-2 ... oops I just did.
That should make it alright again then..
