The Ultra controller is very sturdy and ready for high load excursion. Plus the new generation has inherited much of his qualities.

I add the Sledge 800w amplifier efficiency is much higher and has some added features that the platform does not incorporate Ultra BASH.
They removing biases and a bandage on eyes, both in the same room and tested, are sonically indistinguishable.
Where if there is some difference of 3dB +, Sledge is the Ultra, where the engine driver has major changes to maintain a slight distance.
