Krell KAV-250a/Thiel 3.6 questions

Anybody out there running Thiel 3.6's with this amp? I've put together my first HT with 4 Thiel 3.6's and an MCS-1. I'm driving them all with a KAV-250a 2-ch amp and KAV-250a/3 3-ch amp. My preamp is the 5.1 version of the Krell HTS. The previous owner was using these speakers in a HT with a Theta Dreadnaught. I've just replaced two mid-range drivers in the front channels and am wondering if I just pushed the volume a little too far or if I've got a synergy problem???

Speaker cabling is Audioquest Bedrock and ic's are audioquest diamondbacks.

Can an amp thats starving for power torch drivers like this?
