Dan D'Agostino

Dan D'Agostino Momentum C2 is a Complementary Four topology preamp using four JFET transistors in a complementary differential circuit. Provides an input impedance of more than 1 mOhm, reducing noise and improving signal quality.

The preamp plays a crucial role in music playback due to the moment at the playback stage when the music signal is particularly at risk of being degraded by noise and distortion. The use of three separate enclosures in the Relentless preamp design – a separate sound enclosure for each channel separated by a power/control section — solves these problems, as well as brings other benefits.

The specified performance figures are impressive: 500 W into 8 ohms, doubling to 1,000 W into 4 ohms and 2,000 W into 2 ohms. This places the Momentum Z among the most powerful home audio amplifiers, but sheer power is only part of the story. The main focus lies in how that power is controlled. The Kinetic Drive Regulator uses a hybrid of MOSFET and bipolar transistors to stabilise the amplifier against fluctuations in the mains supply and varying speaker loads, reducing noise, lowering distortion, and ensuring more consistent control of demanding loudspeakers.

Thanks to the extensive developments previously applied to the individual components of the Momentum series, the integrated Momentum MxV amplifier realizes the potential that the integrated solution offers. The integrated Momentum MxV amplifier is a modular design that can be customized according to the listener's preferences.

The Relentless Epic 1600 mono amplifier is a truly balanced design, but unlike conventional bridge amplifiers, the Relentless Epic 1600 mono amplifier uses a single interface topology based on a modern mirror circuit to produce symmetrical plus and minus guides.
