Technics SE-A5000 (1991) | G series

 

The Technics SE-A5000 is a high-end, vintage stereo power amplifier introduced in 1991 and manufactured until 1994, known for its significant weight, robust build quality, and "New Class A" amplification technology. It is basically a gold coloured face-lift of the "tried and tested" SE-A100.           Features & Build:

- ClassAA Amplification: The amplifier incorporates Technics' proprietary ClassAA circuit, which uses separate voltage control and current drive amplifiers to eliminate switching distortion, providing some of the benefits of Class A sound without the inefficiency and overheating issues.

- VC-4 Indicator: The unit is equipped with a VC-4 indicator to visually confirm the operation of the voltage control and current drive amplifiers.

- Power Meters: It features large power meters that can directly read power from 0.0001W up to 300W.

- Robust Construction: The amplifier is built with a highly rigid chassis, a 10 mm thick bronze glass front panel, and extensive insulation to suppress mechanical vibrations and magnetic radiation.

- High-Quality Wiring: Oxygen-free copper (OFC) bus bars and LC-OFC/OCC cords are used for internal wiring to enhance low-frequency resolution.

- Electronic Speaker Selector: It includes an electronic speaker selector with gold-clad contacts for high reliability and a memory function that retains settings after the power is turned off.

For maximum performance the A5000 was partnered by the dedicated C5000 control amplifier. The Technics SE-A5000 was primarily a custom-order item in Japan during its initial release (1991-1994) and today is considered a rare vintage item.
