Did you dampen your Heresy IIIs? It looks like you said you did but I couldn't tell with all of your humor!
I'd be open to dampening my Forte IIIs but I'd like to hear and see about it first. I've never cracked them open.
Tonight, if I get time, I'm going to run a homemade 300b amp into the Forte IIIs. I put high end parts into the amp (Mundorf premium caps, Takman resistors) and it has a really nice layout internally with massive transformers (power and output). I'm curious to see if I get some magic going.
