Tdavism,
I can't speak for the Theta processors but the Dreadnaught is very well made. I bought mine over 4 years ago and never have any problem. Dreadnaught does run hot, especially with all five channels running. If you put it in a closed environment, you will definitely shorten its life expectancy. But put it on an amp stand in the open, it will last a very long time. Besides, for the price of a new II you can almost buy two used Dreadnaughts that will give you a backup as well as bi-amp possibility.
