Not sure if I have enough oomph.

There is a ton of pop in those amps. Yes adequate for what you need. 2’s are not the easiest to drive out there. I passed up a pair because I didn’t have the amp to drive them at the time. Adding more power won't get a lot more. +3db to double the power. These Krell's have a lot of headroom for dynamic passages and absorb the electrical phase shift with ease. I would venture a guess and say they would actually work well together!
