I like those two posts between you and dlaloum

He knows the stuff but he often got "power" and "current" mixed up slightly, and might confuse the issue inadvertently. There, he said "Basically the AVR could not supply the require current to the speakers - power was fine, as my listening levels and speaker efficiencies only...."
The confusing part is, if the AVR could not supply the require current, then power was
not fine. Unless fine does not really mean fine lol... We need to remember voltage, current, and power are 100% related so if the value of one changes, it will affect another. Yes, that's even just for resistor load. Sorry, nothing to do with what you are saying, just want to make sure the OP won't get confused that power may be okay even if current is not.
