A State of the Art Phonostage delivers exceptional sound extraction from vinyl records. With fully balanced, discrete, complementary circuitry. Independent MC x 2 and MM x 2 inputs. Independent loading for each input. Passive RIAA and 4 record label specific EQ curves employing zero negative feedback. Handcrafted with luxury materials, this preamp redefines high-fidelity listening experiences.
Locked inside the grooves of every vinyl record is the most realistic, most natural, most moving sound one could ever experience. The trick is getting that sound off the record and into your speakers. The result of tackling the pursuit of what seemed like the unattainable is the Momentum Phono Preamplier. With the Momentum Phonostage, every last bit of music hidden in even the most microscopic fluctuations in the finest vinyl records is extracted. Paired with the Momentum HD Preamplifier and the Momentum M400 or S250 leaves only wonder and awe.
Dan D’Agostino Master Audio Chooses Its Challenges, Then Pushes Beyond.
By combining the finest possible analog circuitry with the precision of digital control. Every adjustment is right there on the front panel of the Momentum Phonostage, with its own LED readout. Pushbuttons on the front precisely control gain, resistive loading for the two MC inputs, resistive and capacitive loading for the MM input, and record EQ curve.
Knowing that even the best circuitry is no better than the electricity that powers it, the Momentum Phonostage uses a special AC power supply. Not one but two separate power supply components: a transformer that sits on the floor, and power rectification and regulation circuits built into the base on which the Phonostage sits. Thus, the sensitive phono preamp circuits are double-isolated from the transformer electrically, and also separated by a safe physical distance.
The Momentum Phonostage has numerous inputs to handle multiple tonearms and turntables. It has two moving-coil inputs and two moving-magnet inputs, each with XLR and RCA jacks, plus XLR and RCA outputs. The Momentum Phonostage was born without limitations.
As with all the other products from Dan D’Agostino Master Audio Systems, each Momentum Phonostage is built by hand in the Arizona factory.
