Audiobroke, thanx for the input - even if you somewhat overlooked that my question was kinda rhetoric... My main point was that there's obviously something heavily compromised in KAV-400xi power supply. Some "empty" watts, with no current enough, as you'd say...
Someone, on another forum, pointed out the whole thing with a very colorful comparison, refering to powerful output transistors and poor power supply to feed them, something like "...a big enough male organ, but with no blood enough to lift it up..."
