State of the art mono power amplifier.

HÄNDEL is a class A power amplifier. As energy efficient as the design is, the quiescent current flowing through the output transistors generates heat. One square meter (1 m2) of heatsink surface per monoblock dissipates a lot of energy, allowing HÄNDEL to run as cool as possible.


Perfect symmetry – ultimate harmony.

Strictly balanced architecture
The Georg Friedrich Händel features a completely balanced architecture, with no back and forth conversion. In consequence, two tightly coupled amplifiers are employed, one driving the speaker+ and one driving the speaker- terminal. While this doubles costs, it relieves the circuit ground from carrying the speaker return currents, resulting in a clean and unspoilt ground potential.

Ultra wideband design
The high quiescent current Class A design of the preamp and driver stages enables a core speed close to 1.5MHz, slowed down only by input and output filtering to match real word requirements. With filters in place, the small signal as well as full power bandwidth (!) measures an impressive 400 kHz. The lower frequency limit is around 0.3 Hz. No coupling capacitors are used throughout.

Efficient Class A design
The Händel monoblocks use an efficient Class A design that offers all the properties of pure Class A while reducing power consumption and thermal stress on the electronic parts. This is done with a combined switch-mode pre-regulator and an analog tracking post-regulator. The output voltage of this arrangement is the basis of all other supply voltages used in the amplifier. Because of its stability, the amplifier doubles the power when the load impedance is halved (perfect voltage source behavior).

Inherently low noise
High resolution audio is intrinsically tied to low noise and low distortion. System noise is the lower resolution limit of an analog system, because it determines the smallest signal not masked by a noise floor. Hence, low noise levels and thus a wide dynamic range are desirable. The A-weighted output noise measures less than 20µV; this is the blackest of all black backgrounds. Period.
