Maybe. Difference is ~4.4db before power compression which is going to be significant @ 2750w per driver. It's entirely possible for power compression to completely eliminate that gain in amplifier power, not to mention he'd be 1kw over the RMS rated power per driver running at full power. The difference between his current power level and running them at rated power wouldn't be audible enough to make the upgrade worthwhile. By the time you factor in the cost of the amp & the additional electrical needed to support it you are in the realm of diminishing returns going with either option, in my opinion. And that youtube video of the clamp test is entirely useless. Put no faith at all in it.
