Music Hall analogue a3 phono preamp

Music Hall analogue a3 phono amplifier

A SOLID YET MUSICAL PHONO PREAMP DESIGNED AND BUILT AROUND 2 VISIBLE 12AU7 MEDIUM-GAIN DUAL TRIODE TUBES—VALVES KNOWN FOR THEIR COMBINATION OF WARMTH, SPEED, AND DETAIL.

form and function

Your phono amp no longer needs to be relegated to a tiny box aside your component stack; at 10” wide, 7” deep, and weighing 6 pounds, the a3 is a substantial component, equipped with electronics that are on par with the best rack-size phono amplifiers.

an emphasis on sonics

As with anything music hall does, the analogue a3 was designed in the service of sound. From the substantial aluminum alloy chassis to the careful selection of internal components, nothing was spared—nor added—for any reason but to maintain signal purity.
