HD 53 N Headphone Amplifier
HD 53 N is a very high grade headphone amplifier as well as a complete HiFi-solution for music lovers with headphone priority.

Due to the integrated power amplifier HD 53 N can be the centre of a very high grade music-listening-equipment.

HD 53 N incorporates a truly balanced circuitry and consequently offers balanced headphone operation as well as a balanced speaker output.

Of course a standard unbalanced headphone terminal is also available.

Balanced operation makes the signal very clean due to independence of the ground level. The slew-rate is twice of the unbalanced output. Regardless of the headphone type used the improvement is easy to hear.
