The Dan D'Agostino Momentum Phonostage is the ultimate reference phono preamplifier, engineered to retrieve every microscopic nuance locked inside the grooves of fine vinyl records. Available through Trimira Audio, Brisbane’s destination for ultra-high-end analog playback, the Momentum Phonostage combines ultra-quiet discrete analog circuitry with the precision of digital micro-control.
Designed to accommodate complex analog setups with multiple turntables or tonearms, this flagship phono stage provides exhaustive cartridge loading adjustment and historical equalization curves delivering absolute fidelity, vanishingly low noise, and effortless dynamic scale.
Key Features & Engineering Innovations
-
Ultra-Low Noise Signal Path: Built specifically to protect the microvolt-level signals produced by phono cartridges, maintaining dead-silent backgrounds and liquid transparency across the entire audio spectrum.
-
4 Independent Tonearm Inputs: Features 2 Moving Coil (MC) inputs and 2 Moving Magnet (MM) inputs—each equipped with both balanced XLR and single-ended RCA connection options.
-
5 Selectable Historical EQ Curves: Front-panel pushbuttons allow instant switching between standard RIAA, Columbia, Decca FFRR, DGG (Deutsche Grammophon), and RCA Victor Orthophonic equalization curves to correctly decode historical pressings.
-
Precision Front-Panel Digital Control: Conveniently control gain ($\pm 6\text{ dB}$ trim), 16 resistive loads (for MC and MM), and 16 capacitive loads (for MM) directly from front pushbuttons with dedicated LED parameter readouts.
-
Double-Isolated Power Supply Architecture: Employs a dual-chassis power configuration comprising an outboard floor transformer and secondary rectification/regulation circuits built directly into the machined isolation base under the unit.
-
Zero Global Negative Feedback: Pure direct-coupled, fully balanced complementary topology ensures fast transient response, organic harmonic stability, and immense soundstage depth.
