I own PSB Alpha Mini Speakers, bought in 1997. The input power is 10-80 watts. I am interested in upgrading my receiver to the Denon 7.1 AVR3805 120 watts per / ch x 7. My speakers may be 7 years old but still sound excellent. Will the Denon 3805 be to powerfull for the speakers? My second choice is the Denon AVR2805 100W x 7.
