Vacuum Tube Integrated Amplifier
The EVH implements EKCO’s signature valve amplification techniques into a headphones and pre amplifier system, for a beautifully intricate performance in its purest form. EVH is dedicated to achieving the best possible sound quality from any set of headphones connected to it. As a powerful headphone amplifier, the EVH uses 6SN7 vacuum tubes in triode mode for delightfully natural tonal characteristics.
The circuit has no overall loop feedback, and the Negative Feedback (NFB) technology lowers the output impedance, reduces distortion and improves the overall frequency response. This brings obvious benefits to sound reproduction.
A whole host of connections; 3-pin balanced, RCA, USB, coaxial, and optical inputs make it easy to listen to music without ever having to ponder on decoding different formats.
A smart toggle switch on the front panel switches the features from headphone amplifier to pre-amp system. EVH is perfect for enjoying music personally via your hi-fi system too as an integral pre-amp.
