Right I finally got around to testing it. The first version has a glitch, and the left side works but the right was monumentally messed up.
So to test the concept I created a franken-circuit, excuse the crappy photos.
I used (per channel) 2x 47ohm 0.75w resisters in parallel since I couldn't find any 24ohm resisters that could carry the current
and 1x 4.7ohm 0.6w resister
And wow it really does waste power, I haveto put the STX on extra high but at 40% max.
I am running 2x AD797BR opamps, which nullifies the crappy bass of the JRC, but retains the sharpness (which I dont like, but it helps identify differences) and increases clarity.
Overall I notice the highs are back to normal, which is still bright in the D2000, but thankfully not painful, it actually makes the aggressive sound of the AD797 bearable.
I dont know if its affecting the SQ, I have a feeling it is but it could very well be my franked adapter, It should improve when I solder it in place, or its just that the AKG K242HD has some serious synergy with the AD797.
Bass is still as hard hitting as ever, but its definately clearer and not there when not needed.
whether its worth the effort.... I wouldn't say it isn't, but I wouldnt say it is.
Since I have some spare power to play with, can I bump up/down the resistor values to get a stronger effect (lower output resistance) ?
EDIT: I would say I have exactly 50% more power then I am using now to waste before I put stress on the STX components (keeping volume lower then 76)
