I have a pair of Reference Monitors & I drive them with a McCormack DNA-1. I think it is a little overkill but I could be 100% wrong. I have never heard the speakers break up when pushed but I am afraid to really crank them for any length of time. I have not heard either speaker you are interested in but after hearing what I have now I can't imagine switching to any other brand. I will go up the Tyler line line when the upgrade bug hits again.
