7BSST
The 7B SST single-channel amplifier employs a balanced-output design that reduces THD and IMD to unprecedented low values (typically 0.001% or less) . With a low noise floor (typically below -118dB) and excellent signal tracking characteristics (slew rate of 120 Volts per microsecond), the 7B SST monoblock assures a new degree of transparency, musicality, and ease of listening. Capable of delivering 900 Watts continuously into 4 Ohms, and with tremendous power reserves, the 7B SST offers virtually perfect freedom from overload on any type of speaker or music.
