D’AGOSITNO MOMENTUM HD PRE-AMPLIFIER RAISES THE BAR
Dan D'Agostino has told us about the new Momentum HD Preamplifier. This is a major upgrade to the Momentum Preamplifier.
Building on the already impressive Momentum Preamplifier, the new design earns its HD status due to the High Dynamic and High Definition improvements. The upgrades to HD includes advancements in the power supply, audio circuitry, and control sections.
Momentum HD Preamplifier Upgrades
Firstly, power. The D’Agostino Momentum HD Preamplifier's main power transformer, housed in a separate chassis for maximum isolation, is 33% larger than the original Momentum. Furthermore, the unique winding technology, first employed in the Momentum M400 Amplifier, delivers greater power output from the same footprint. The result of this power upgrade is that the output stages are now operating at a 36% higher voltage rail.
Additionally, there is an entirely new discrete differential FET input stage. Here you will find two current sources per leg and an input impedance greater than 1MOhm. The input stage is therefore isolated by the ultra-high input impedance and so the entire audio signal path from external variables.
Bluetooth tech is now featured in the included remote control. Bluetooth has been used to extend the remote's range five times compared to the original. Moreover, it eliminates any line of sight limitations inherent in IR remote controls. Also, there's a newly designed tone and volume control circuitry.
Finally, there has been a refresh to the industrial design of the Momentum for the HD. The signature copper elements have been reshaped to more resemble the Momentum M400 and S250 amplifiers' aesthetics.
The Momentum HD Preamplifier will be available in silver or black and has an MSRP of $40,000 USD.
However, if you are an existing Momentum Preamplifier owner, you can upgrade to Momentum HD Preamplifier electronics. Naturally, the original metal work will be untouched. Pricing for original Momentum Preamplifier owners to upgrade is $7,500 USD.
We are awaiting confirmation of UK pricing.

They are not automatically given with all reviews, nor can manufacturers purchase them.
The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
