Dan D’Agostino Momentum HD Preamplifier
Momentum HD Preamplifier is a major upgrade to the Momentum Preamplifier.
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.
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.
