Hifisoundguy all i can say is i have a RITA-880 driving a pair of 82db Acoustat 1+1s and doing a great job this is no regular 45 watts per channel amplifier it replaced a Bow Wazoo XL 75 watts per channel very good amplifier BUT for my tastes i prefer the RITA-880 and it,s believe it or not MORE powerful than the Bow Wazoo XL AND ALL THIS WITH ONLY 170 hours on the unit i was told it will reach it,s full potential after 300 hours even if the sound stays the way it is now i would be very pleased.
