Late-night vinyl in a study is easier when the phono stage and headphone amplifier sit together beside the turntable. UltraPhono combines a configurable MM/MC phono stage with a Class A headphone amplifier, making it useful beside a turntable when private listening is part of the routine. The front volume control provides stepped, repeatable adjustment rather than a basic add-on socket.
Gain, cartridge loading, mono and subsonic filtering cover the setup needs of a wide range of moving-magnet and moving-coil cartridges. The headphone stage can drive demanding loads while the line output feeds a normal stereo amplifier.
UltraPhono is the compact choice when headphone listening and cartridge adjustment need to share one position beside the deck.
