"Transparency is hard to explain but it's like the effortless lows coming out of a pipe organ. I have been wondering the last few months if it is possible to have transparency AND faster attack/decay/tighter punch all from the same sub."

Yes, I think that this is possible. You will have to nearly double the price and go with the JL F113 though. This sub is about $3200 and weighs in at about 130 lbs although it is the size of the EP500. It has a sealed enclosure and is supposed to have a very fast attack/decay even though it extends down to below 20 Hz flat. This is the sub that I have my eye on, but I don't know if I will ever be able to get $6,000 together to get two of these subs.
