ha25.3 headphone amplifier

WE DESIGNED THE MUSIC HALL HA25.3 TO IMPRESS HEADPHONE LISTENERS WITH UNPARALLELED MUSICAL PROWESS.

hybrid

The ha25.3 is a fully balanced tube & solid-state (hybrid) headphone amp that uniquely doubles as a two-input stand-alone tube pre-amp.

tube + solid state

Basic looking on the outside yet sophisticated on the in. Under the hood, we’ve married a tube pre-amp section with solid-state amplification. This provides you the rich robust sound of tubes with the speed and punch of solid-state.

Put simply, the music moves you.
