Coming from someone that has lost a lot, I hope you seriously considered John's advice first.
Sure, I have an external amp, but I don't listen at the volumes you do.
I'm not trying to be melodramatic, and I'm not discrediting other people's opinions. But just as I would discourage a friend or family member to listen at the levels you are, I have a moral obligation to do the same to you.
It obviously your choice, but given the possible harm, it's one that merits some serious reconsideration.
Peace, buddy.
