For anyone interested here is some god info:

for onkyo at least:
from a Onkyo manual: "A home theater system automatically calibrated by Audyssey MultEQ® XT32 will play at reference level when the master volume control is set to the 0 dB position. "
When switching volume display from "Absolute" to "Relative (THX)": "The absolute value 82 is equivalent to the relative value 0 dB."

Seems 0db is not maximum power but 85dB reference level anything above that is greater than reference level.
I have my amp limited to 0db even though it goes to +15 but I rarely get above -15db
OK, I get that, but we're talking about a Kenwood 605 for Chripessakes!

My statements are based on the OP and I'm not going to start spinning off into other products.
