Limited experience with 300Bs. I started with the EHs, then I tried the Sophia Royal Princess, I preferred the EH by a narrow margin. I have since gone with the Elrogs and have been very pleased, they check all of the right boxes for me, really outstanding. I have been considering the EML mesh plates but am in no hurry as long as the Elrogs are still kicking.
These have all been driven by my Bottlehead Kaiju.
Best,
