Thanks for the info, I almost bought Dekoni pads, the bass in ebony is right now just prefect for me, I want nothing less and nothing more.
I can actually check the Dekoni measurements on the Ebony. What I wrote applied for the TH900 (at least directly). On the Ebonies the Dekoni sounded nice. Actually I could publish these, the problem is my Ebonies are not burned in yet, and people might draw premature conclusions from measurements.
