The Rotel RB-1590 power amplifier operates in class A/B and outputs 350 watts at 8 ohms with both channels operating simultaneously. It is ideal for large listening rooms and for less sensitive speakers that require a fair amount of power to achieve the best sound quality with realistic dynamics. The RB-1590's impressive power is based on a solid foundation consisting of a pair of massive toroidal transformers designed and manufactured by Rotel.
