I agree completely. I find that while my Onk can't dish it out like the ADA, the Onk is about as much as I can take.

The 1500 is perfectly matched for the M100's dynamic range BTW. The M100 compresses within 5V of the 1500 hitting its rails. Of course by that time, ear drums will have given out. That's right around 116dBC @ 3 feet. Of course the SPL could be higher than that because my meter may be missing the true peak. I sit 13 feet away, which in my room places me in the diffuse sound field, and leads to 112dBC at that power level. That's about 9dBC more than my ears are comfortable with.
