About the Momentum HD
The Dan D'Agostino Momentum HD Preamplifier is a reference-grade, solid-state preamplifier designed for uncompromising audiophile performance. Building on the award-winning Momentum platform, the HD version introduces significant upgrades in power supply, audio circuitry, and control systems. The main power transformer is 33% larger than its predecessor, utilizing advanced winding technology for greater current delivery and dynamic headroom. The audio path features a new discrete differential FET input stage with ultra-high input impedance (>1MΩ), isolating the signal path from external influences and revealing extraordinary detail and musical nuance. The preamp offers a fully balanced, complementary circuit topology, a precision ladder volume control with 1dB steps in the critical listening range, and a Bluetooth remote for convenient operation. With six balanced XLR inputs, two balanced XLR outputs, and meticulous construction, the Momentum HD sets a new benchmark for transparency, dynamics, and musicality in high-end audio.
