An arc welder might do the trick ;-)
Seriously, I love the Mani2's, but yes, they are a tough speaker to drive. Need a high current amplifier; unfortunately, this is one speaker that you can forget about with tubes. The Sim amp recommendation is a good choice, sounds good with Totems in-general. I would imagine one of the beefy McCormack amps mentioned above would also work nicely. My suggestion is probably well above your price range, but the Rowland Model 10 and Mani-2's, you may never change again. Terrific combination.
