SAE 8300 8 Channel Amplifier

$ 19,500.00

The SAE 8300 8-channel amplifier was designed to set new standards in virtually every performance category. Each channel uses a dual-differential balanced design with a 4-quadrant input stage to nudge the edge of the art in such categories as signal-to-noise ratio, slew rate and ultra-low distortion.

This product is a special order, custom-built.*

Other significant advances in the amplifier include:

  • Dual design with separate and independent power transformers, power switches and line cords for each channel bank;
  • 300 Watts Per Channel RMS @ 8 Ohms; 450 Watts Per Channel @ 4 Ohms:
  • High temperature (Class F rated) toroidal transformers;
  • Dual temperature sensors and low-speed cooling fan to maintain proper operating temperatures.
  • Four layer circuit boards used throughout; each with separate power and ground planes;
  • Current feedback for improved amplifier control and virtually unlimited slew rate;
  • Double transistor input stage;
  • Dual-DC Servos virtually eliminate any DC offset;
  • ThermalTrak© output devices optimize bias in real-time;
  • All protection circuitry is optically coupled and outside the circuit path. It is self-resetting;  
  • Designed, Engineered, and Manufactured in the USA

Description

50 years ago SAE’s first component, the MK 2 stereo amplifier, rearranged the amplifier world’s power structure. Per Stereophile, a pair of MIKII’s had sweeter highs and dramatically improved bass when compared directly with the audio industry’s then acknowledged “best”. Our latest flagship, the dual-mono 2HP-D, repeats the exercise challenging all-comers for the title of world’s best amplifier.

Our 8300 shares philosophy, goals and topology with the 2HP continuing SAE’s diligent effort to achieve perfect musical reproduction. Power output is 300 Watts RMS per channel at 8 ohms and 450 Watts RMS per channel at 4 ohms, FTC Power Rule Rated. With channels on-hand arranged in two independent banks of four, the 8300 is entirely suitable for use in exacting multi-channel home theater applications or for multi-amping any audiophile oriented stereo system.

To maximize the power output, the 8300 has two independent power supplies each with its own massive 1950VA transformer, power cord and AC switch. . And it is the first SAE amplifier automatically ready for world-wide use. On first turn-on, the amplifier ascertains the available line voltage and self configures its transformer taps. And all protection circuits are optically coupled. They never intrude on the listening experience unless they are needed.
