The S/3700e is the first multi-channel home theater amplifier to carry the Threshold brand in the company's 30-year history. Nonetheless, the S/3700e is heir to Threshold's legacy of high-current designs that effortlessly command and control demanding
loudspeaker loads, delivering the power needed for full revelation of dynamic contrasts and bass extension.
But power is only part of the S/3700e story. The amplifier employs minimal feedback, and is direct coupled input to output, with no capacitors in the signal path.
Like all Threshold amplifiers, it utilizes close-tolerance metal film resistors, and matched JFETs. The result is superb open and airy resolution of low-level detail -- the subtle shadings that differentiate musical performances.
Although the S/3700e ships as standard with five channels, its modular construction enables it to be expanded at any time to six or seven channels.
The highly affordable S/3700e brings Threshold's acclaimed designs within easy reach of the film lover who refuses to give up audiophile performance to gain home theater realism.
