IF people were saying that, they are incorrect.
Technically Superman always has the power to shred through Imperiex Probes at his disposal. However, he has to enter a very specific/bloodlusted mindset before he unlocks that power. Your average/standard Superman always mentally inhibits his abilities because he is rarely ever out to kill his opponents(as he was during OWAW.)
The other amps I mentioned were gleaned from external forces, thus are obviously not at his disposal at any given moment.
