    Dan D’Agostino Master Audio Systems has just revealed the Momentum HD Preamplifier, a major upgrade to the company’s award-winning Momentum Preamplifier. The new HD status represents the high dynamic and high definition improvements that have been achieved in this substantial upgrade. The new Momentum HD Preamplifier incorporates advancements in the power supply, audio circuitry, and control sections.

    Housed in a separate chassis for maximum isolation, the Momentum HD main power transformer is 33% larger as compared to the original Momentum Preamplifier. A unique winding technology, first employed in the Momentum M400 amplifier, delivers greater power output from the same footprint. Internal circuitry filters RF noise from the AC powerline, and compensates for asymmetric power waveforms and DC on the mains.

    A completely new discrete differential FET input stage features two current sources per leg and an input impedance greater than 1MOhm. This ultra-high input impedance isolates the input stage and thus the entire audio signal path from external variables.

    Taking advantage of the increased power supply capability, the output stages are now operating at a 36% percent higher voltage. “The increased output voltage has opened up the dynamics on both the micro and macro levels.” D’Agostino continued. “The speed of the dynamic contrasts jump out on a visceral level.”

    Also new is the Bluetooth technology featured in the included remote control. The Bluetooth backbone extends the range of the remote by a factor of five and eliminates line of sight limitations that are inherent in IR remote controls.

    Newly designed tone and volume control circuitry increases range and precision in both circuits.

    Aesthetics have also been updated with the signature copper elements being reshaped to better match the Momentum M400 and S250 amplifiers.

    Existing Momentum Preamplifier owners will be able to upgrade to the new Momentum HD Preamplifier electronics enhancements preserving value in their initial purchases.

    The Momentum HD Preamplifier will begin shipping in March, 2019 for $40,000 USD and upgrades for original Momentum Preamplifier owners will be $7,500 USD. Standard finishes include silver or black.
