Know before you buy
With 500 watts per channel into 8 ohms and 800 watts into 4 ohms, the S5 is designed to drive even the most demanding, low-impedance loudspeakers with ease. Its high-current design ensures it can maintain control over difficult woofer loads, making it an excellent match for high-end floorstanding speakers.
Yes, the dual monoblock architecture provides complete electrical and physical isolation between the left and right channels. This minimizes crosstalk and interference, resulting in a wider soundstage and more precise imaging.
As a powerful Class AB amplifier, the S5 generates significant heat and consumes up to 1200 watts during operation. It requires a well-ventilated space, preferably on an open shelf or rack, to ensure proper airflow and longevity of the internal components.
Yes, the S5 includes both RS232 and Ethernet connectivity. These ports allow for seamless integration with third-party control systems, enabling remote power management and status monitoring.
At nearly 133 pounds, the S5 is exceptionally heavy. You should ensure that your audio rack or furniture is rated to support this weight and that the shelf is deep enough to accommodate its 18.25-inch depth.
Rhodium is an extremely durable, corrosion-resistant metal that provides an excellent, stable contact surface for your speaker cables. These custom 5-way posts ensure a secure connection that maintains signal integrity over the long term.
