Topping EHA5
Electrostatic Headphone Amplifier Balanced 700Vrms
Most electrostatic headphones offer excellent musical potential, but their performance is often limited by the associated headphone amplifier. The Topping EHA5 electrostatic headphone amplifier helps your headphones to reach their full potential, with detailed and dynamic sound reproduction.
This headphone amplifier will work perfectly with STAX electrostatic headphones or even Kingsound.
An incredible reserve of energy
Topping's EHA5 offers a large power reserve to accompany demanding electrostatic headphones. With an output level of 700Vrms and 2000Vp-p, it will have no trouble driving the vast majority of headphones with efficiency.
12V Trigger
The Topping EHA5 provides a 12V trigger input that can be connected to other devices to automatically turn the amplifier on and off. It allows a practical and fluid use to enjoy the best of your music.
Pass-through feature
When the headphone output of the EHA5 is switched off, the input signal is routed directly to the balanced XLR and single-ended RCA outputs at the rear. This allows the EHA5 to be used with electrostatic headphones as well as with other audio devices with a preamp function.
