I have Paradigm Titans, a CC-170, and Atoms being pushed by an Onkyo Sr501. I want to calibrate them (I bought Avia), but after reading some posts on the subject, I'm worried about damaging my speakers in the process. Can my set-up handle calibration at the suggested levels? I have no idea how loud reference levels will be, but I imagine it will put some stress on the Digms, and I'd hate to "pop" an Atom. Anyone have any experience with calibrating these speakers or like speakers?
