^^ on a related note Gorilla's post did make me remember one thing, the S8's are running at 8ohm so 3dB difference right there. So when I sent a -12dB signal through my system the Sunfire was running 8 ohm on the S8's and 4 ohm on the 212 so that would bring the true spread in my check back to 6dB. Sorry guys I may have been off on my first post about this and without specifically measuring the input wattage it is probably a little "off".
