Hafler DH-120


As a direct descendant of the DH-220 amplifier, the DH-120 employs the latest MOSFET technology with all silicon devices in a direct coupled configuration (except at the input).

With its own unique circuit, the DH-120 utilizes the latest circuit topology and capacitor interfacing for superior sound quality in either stereo, or in the bridged mono mode.

The MOSFET output devices provide exceptional reliability and resistance to abusive operating conditions, and avoid the need for special protective circuits which compromise audio performance.

Their ruggedness and self-protective capability enables the DH-120 to deliver very high currents into very low impedances, even into a short circuit, affording audible benefits when driving difficult loudspeaker loads.

This unique Hafler design gives you the three primary benefits: circuit simplicity, added reliability, and better sound, all at reasonable cost.
