Know before you buy
The AAVA (Accuphase Analog Vari-gain Amplifier) system eliminates traditional variable resistors in the signal path. This prevents impedance changes and signal degradation, ensuring the audio remains pristine and accurate at any volume level.
A damping factor of 500 indicates the amplifier has excellent control over the movement of your speaker drivers. This results in tighter, more precise bass response and reduced distortion, especially in demanding low-frequency passages.
Yes, the E-280 features two expansion slots on the rear panel. You can install dedicated Accuphase option boards to add features like a high-quality DAC or a phono stage for your turntable.
With a power output of 120 watts into 4 ohms and a robust double parallel push-pull configuration, the E-280 is designed to handle a wide range of speakers. Its low-impedance output circuitry ensures it maintains stability and control even when speaker impedance drops.
The XLR inputs provide a balanced connection, which is superior for rejecting noise and interference over longer cable runs. The RCA inputs are standard unbalanced connections suitable for most traditional audio components.
As a Class AB amplifier, the E-280 will generate heat during use. It is important to place the unit in a well-ventilated area with sufficient clearance on the top and sides to allow for proper airflow and heat dissipation.
