D'Agostino Momentum C2 Preamplifier

The Momentum C2 Preamplifier builds upon the legacy of the Momentum HD with a groundbreaking audio topology, featuring four JFET transistors arranged in a complementary, differential, push-pull configuration. This design dramatically increases input impedance and reduces noise, resulting in exceptional performance and stability across all system configurations. The discrete, dual-complementary differential JFET input stage ensures precision and clarity, delivering an unparalleled audio experience. For recordings that don't meet audiophile standards, the preamplifier includes transformative tone-control circuitry that remains completely transparent when inactive, ensuring it doesn’t impact the signal path. A discreet headphone jack, hidden behind a front panel door, allows for private listening with independent amplifier circuitry, offering the highest level of refinement for personal audio enjoyment.

The power supply in the Momentum C2 Preamplifier is housed in a separate chassis, ensuring maximum isolation and optimal power delivery. This advanced power supply connects to the audio chassis through a 20-amp interlocking connector and features custom toroidal transformers dedicated to analog and digital circuits. The design also incorporates internal circuitry that addresses RF noise and powerline irregularities, ensuring that only the cleanest power reaches the system. Designed with both function and aesthetics in mind, the Momentum C2 features a bi-directional remote control crafted from precision-machined aluminum and Delrin®. The ergonomic design, paired with an LCD screen, allows intuitive control of the preamplifier’s functions, mirroring the information displayed on the front panel for a seamless user experience.

For those seeking the best in digital performance, the Momentum C2 offers an optional Digital Streaming Module (DSM) that provides connectivity for legacy sources, USB functionality, and premier streaming capabilities. The field-upgradable DSM adds SPDIF coaxial, optical, USB-B, RJ45, and Wi-Fi network inputs, and supports 10/100/1000 Gigabit Ethernet for latency-free playback of high-resolution content. Tailored iOS apps make it easy to control music collections, streaming content, and unit settings, with native integration for services like Tidal, Qobuz, and Spotify, as well as Tidal Connect. The DSM also supports MQA decoding and Roon Ready certification for those who prefer alternative music management systems. With its ability to decode PCM signals up to 32-bit/384 kHz and DSD256 (11.2 MHz), the DSM ensures the highest resolution and quality. Internal balanced connections carry the final analog signal directly to the preamplifier’s input circuitry, fully leveraging the power and precision of the Momentum C2’s analog circuitry.

Designed with precision and elegance, the Momentum C2 Preamplifier is as visually striking as it is functional. The bi-directional remote control offers intuitive control over the preamplifier’s settings, with an ergonomic design and LED screen that reflects the information displayed on the front panel. This seamless integration of technology and design ensures that every aspect of the user experience is refined and sophisticated.
