I wouldn't spend a lot of time worrying about them in this case. Most of the specs you've posted are less than honest ways of rating equipment, ie power output at 1% distortion with only 1 channel driven, at 1kHz instead of 20Hz-20kHz, and a 6 ohm load instead of the usual 8.

Of course, if you really want to learn all about ohms and decibels, this would be your starting point: AV University — Reviews and News from Audioholics
The latest article is all about ohms, which I'm sure you'll find to be fascinating reading material :D

For a quick primer on dB, this link is pretty useful: Peak SPL Calculator

Ok. thx to all. I like that onkyo.

with those specs i posted......what do you all think of the current amp I own? thx.
