The NuPrime STA-9, a 2 x 120W Class A+D stereo amplifier coupled to a 290W mono amplifier, is designed with an improved even-order harmonic circuit that mimics the most attractive sound characteristics of tube amplifiers without the disadvantages of lamps and limitations. The spacious, transparent, dynamic and luxuriously textured STA9 sound stage must be heard to believe it.
