Dan D'Agostino - Momentum C2 / C2Z - Preamplifier

The Dan D'Agostino Momentum C2 and C2Z Preamplifiers represent the latest evolution of the company’s reference-level analog engineering, combining fully balanced discrete circuitry with substantial advancements in noise reduction, dynamic performance, and signal integrity. Designed for uncompromising two-channel systems, the C2 platform delivers extraordinary transparency, control, and musical realism.

At the core of the design is a newly developed complementary four-FET input stage operating within a fully differential topology. Combined with upgraded power supply architecture and ultra-low output impedance, the Momentum C2 and flagship C2Z provide exceptional bandwidth, transient speed, and effortless system matching with even the most demanding power amplifiers.

The Momentum C2 platform also supports the optional Digital Streaming Module for high-resolution digital integration while preserving a purist analog signal path. Precision-machined aluminum and copper chassis construction, a redesigned OLED interface, and the signature Bluetooth remote with integrated display complete a preamplifier engineered to the highest standards of performance and craftsmanship.
