Professional calibrator brought up a good point

[ParadigmDawg]

When I asked him about it afterwards his argument was that my processor at the time, (The UMC-1) was the problem. He pointed out that many people had complained that the UMC's test tones were loud. But he had it cranked up so loud that I took my parrot out of the room and went upstairs. I should have stopped him right then. I'm not sure why I didn't.

I actually had an EMO amp blow one of my tweeters once during calibration.

I just listened to that Emo driving some Floyd through Sig8's.

You probably don't hear this often but that thing is huge.
