Know before you buy
Class A operation ensures that the amplifier transistors are always fully conducting, which eliminates switching distortion. This results in a highly refined, smooth, and detailed sound signature that is particularly effective for critical listening.
Yes. With a six-fold parallel push-pull configuration of power MOS-FETs and a high damping factor of 1000, the E-800S is designed to maintain absolute control over speaker drivers, even with challenging low-impedance loads.
Unlike traditional volume controls that use a variable resistor in the signal path, the AAVA system converts the music signal into current, adjusts it, and then converts it back to voltage. This eliminates impedance changes and noise, resulting in exceptional clarity regardless of the volume level.
Yes, the E-800S features two expansion slots on the rear panel. These allow you to install dedicated Accuphase option boards, such as high-quality phono stages or DAC modules, to suit your specific system needs.
The headphone output is a dedicated, high-quality circuit built with discrete components. It is designed to provide a premium listening experience that matches the performance of the main speaker amplification.
These specialized insulators are engineered to provide superior vibration damping. By isolating the amplifier from external mechanical resonances, they help preserve the purity and stability of the audio signal.
