Dan D’Agostino Momentum Phonostage


The Dan D’Agostino Momentum Phonostage is a masterpiece designed to unlock the full potential of vinyl records, capturing the most intricate details and nuances of the analog audio experience. This phono preamplifier is a testament to the relentless pursuit of audio excellence by Dan D’Agostino Master Audio Systems.

Key Features:

  1. Uncompromising Analog Circuitry: The Momentum Phonostage combines the finest analog circuitry with precise digital control to deliver an unparalleled listening experience. It features intuitive pushbuttons on the front panel that allow precise control over gain, resistive loading for the two MC inputs, and resistive and capacitive loading for the MM input.
  2. Advanced Power Supply: Recognizing the crucial role of clean power, the Momentum Phonostage employs a specialized AC power supply of two separate components. A transformer sits on the floor while power rectification and regulation circuits are integrated into the base of the Phonostage. This dual-isolation approach ensures that the sensitive phono preamp circuits remain electrically isolated from the transformer and physically separated by a safe distance.
  3. Versatile Input Options: The Momentum Phonostage has multiple inputs to accommodate various tonearms and turntables. It offers two moving-coil inputs and two moving-magnet inputs, each featuring XLR, RCA jacks, and corresponding outputs.
  4. Selectable Equalization Curves: The Phonostage offers five selectable equalization curves accessible from the front panel. These include the Standard RIAA equalization curves and four alternatives used by different record labels, allowing for tailored playback to suit various vinyl records.
  5. Hand-Crafted Excellence: Each Momentum Phonostage is meticulously hand-built in the Arizona factory of Dan D’Agostino Master Audio Systems, reflecting a commitment to craftsmanship and quality.
