Not GONA happen! You are asking a planar open back to produce closed back dynamic bass. Not going happen my friend. The only planar that can produce nauseating thunderous bass is the Ether CX with equalizer. I have the old LCD-X (2016)and the new LCD-X (2022) and I drive them with the topping A30/A90. They have sufficient bass for me but they are no where close to TH900, however the CX can get there with EQ.
