The Hercules power amplifier is an ultra linear tube amplifier using EL34 output tubes to produce 30 watts per channel. Boasting premium components, it features a very simple signal path in an effort to provide sonic purity and long-term reliability. The Hercules uses a specially built power supply combined with custom output transformers to allow the amplifier to be heavily biased into Class-A while providing allegedly excellent bass and transient response.
The differentially-balanced input section reduces noise, and a cathode-bias function allows the amplifier to run in Class-A over a larger power range. An automatic mute/standby circuit ramps up the voltage to the tubes gradually for longer life; it also reportedly removes any pops or noise at turn-on. This attention to detail and the simple circuit design offers a musically accurate and satisfying amplifier.
The Hercules power amplifier is currently available for purchase through Audio Electronics by Cary Audio's online store or through your local Cary Audio dealer.
