D'Agostino Momentum C2Z: Reference High-End Preamplifier
The D’Agostino Momentum C2Z represents a radical evolution within the Momentum series from Dan D'Agostino Master Audio Systems, incorporating a new four-complementary-circuit topology directly inspired by the legendary Relentless Preamplifier.
Specifically engineered to complement the D'Agostino Momentum Z Monoblock, the Momentum C2Z introduces a high-current FET output stage optimized to work in perfect synergy with the Z input stage of the Momentum Z amplifiers.

Relentless-Derived Architecture
At the heart of the Momentum C2Z lies Dan D’Agostino’s revolutionary four-complementary-circuit topology.
This sophisticated design:
Dramatically increases signal separation and purity
Reduces background noise
Enhances electrical stability
Delivers exceptional linearity
Preserves musical integrity with maximum transparency
The result is an extraordinarily refined, dynamic, and three-dimensional presentation.
FET Output Stage Optimized for Momentum Z
Designed specifically for pairing with Momentum Z amplifiers, the C2Z’s FET output stage:
Delivers higher current
Improves signal transfer
Optimizes coupling with Z inputs
Enhances dynamic authority and control
Maximizes overall system musicality
Complementary Differential JFET Circuitry
The input stage uses a four-JFET push-pull complementary differential array, offering:
Extremely high input impedance
Ultra-low distortion
Minimal noise
Wider and more open soundstage
Greater harmonic richness
A more natural and organic sound signature
Separate External Power Supply
The dedicated outboard power supply ensures maximum electrical and mechanical isolation.
It includes:
Dedicated toroidal transformers
Separation between analog and digital circuits
Advanced RF noise filtering
Extremely stable power delivery
This architecture contributes to a pitch-black background and exceptionally clean sonic presentation.
Optional Digital Streaming Module (DSM)
The optional DSM transforms the Momentum C2Z into a complete digital reference hub.
Features include:
Ethernet RJ45
Wi-Fi
USB-B
Optical input
Coaxial SPDIF input
TIDAL Connect
Qobuz and Spotify support
Roon Ready certification
MQA decoding
Supported formats:
