[quote user="Brisk"][quote user="gpi"][quote user="Brisk"]I'm happy with the sound although I've been paying it more interest recently. What interests me the most is the difference in manufactures figures and the measured figures. One publication stated the Marantz pm6002 which I own has a measures output of 80wpc not the stated 45wpc into 4Ohm. I think I would pay it more attention if I knew the manufacturers were more consistent.[/quote]
It would be more into 4 ohms instead of 8. Someone else will be better than me at explaining it.[/quote]
Thats what I thought so I doubled checked, they said 50W into 8Ohms and 80W into 4Ohms.[/quote]
That sounds about right, although good amps will double up, so 100W into 4 ohms. The lower the impedance of the loudspeaker, the more current it demands from the amp.
