Eagle 7A

About the Eagle 7A

The Electron Kinetics Eagle 7A is a high-performance Class AB stereo power amplifier designed by John Iverson. It delivers 300 watts per channel at 8 ohms in its standard form, with an upgraded EKSC version boosting output to 430 watts per channel at 8 ohms, 750 watts at 4 ohms, and 1050 watts at 2 ohms. The amplifier features a non-inverting balanced input, two sets of 5-way gold binding post outputs, and a robust power supply upgraded by removing the voltage regulator and replacing large electrolytic capacitors to improve reliability and power delivery. Time domain filters are incorporated to reject ultrasonic signals, enhancing sound quality and amplifier stability. The Eagle 7A is known for its rich and warm midbass, making it particularly effective with speakers that lack bass presence. It has a damping factor greater than 600, harmonic distortion around 0.0035%, and intermodulation distortion near 0.0045%. The amplifier measures 18"x10"x6" and includes a 2-year transferable warranty after upgrade. It is highly regarded for driving difficult speaker loads with ease and providing a powerful, detailed sound signature, although some find its midrange character to have a mild solid-state electronic quality.
