A modern approach to classic sound. The Qualiton A75i is a solid, well-designed amplifier, down to the very last detail. Even the cage feels solid. Compact, yet hefty, the A75i has a warm and unambiguously "tube" sound with an immense soundstage. The Class A architecture provides 75WPC with very low distortion and noise. Effortlessly driving a pair of Qln Prestige Three, this amplifier is the currently the darling of our listening room.
