You should definitely give the Terror bass a try if you haven't already. The clean headroom, hot DI and noisy fan are all easy and cheap to fix, and if you want very clean and very loud there's always the 1000W version!
I went from the Terror to the AD200B, then back again, ultimately because of the light weight and the fact it didn't need regular servicing. The tone is close enough that I was happy with the compromise.
