wally flick Posted December 4, 2012 Share Posted December 4, 2012 I'm upgrading my receiver to add HDMI connectivity. I currently have a 7.1Denon AVR2805 driving an RC-35 center, RF-15 fronts, and RS-25 surrounds/rears.The Denon is rated at 100 watts. The Marantz 1603 caught my eye, but I'm a tad worried that it just pumps 50wpc. Not really pushing the Denon hard as normal listening level for us is-20/-15 dB. I know the speaks are very stingy on power requirement, but itsounds like a lot chopping the output by half. Would also appreciate a review of the Marantz if anyone would like to weighin. Thanks!

CECAA850 Posted December 4, 2012 Share Posted December 4, 2012 You'll need 10 times the wattage to double the volume. Twice the wattage is a marginal increase (3 dB). Quote Link to comment Share on other sites More sharing options...
