The Momentum amplifier from Dan D’Agostino Master Audio Systems delivered magnificently on the initial design goals of formidable power and incomparable finesse from a compact chassis. Worldwide, reviewers, critics, and end users lauded the performance and elegant aesthetic design. Global praise included more than a dozen “best of” awards and the highest ever review scores for sound and measured performance.
The driving force behind the Momentum M400 design, Dan D’Agostino, is constantly creating and revising his thoughts on circuit design and their implementations. What started as an engineering exercise resulted in an exciting new breakthrough that Dan felt compelled to include in the Momentum amplifier. These efforts have led to a substantial upgrade in the new Momentum M400.
The Momentum M400 Amplifier Technology Upgrades
The new M400 moniker gives clue to a major part of the upgrade. Power output has been increased to 400 Watts. This is up from the original 300 Watts. The backbone of the power increase is a new ultra-quiet 1,800VA linear transformer – a 20% increase in size from the original. Coupled to this larger power source is a new output stage design that includes a number of major enhancements.
Feeding every amplifier output stage is circuitry known as the driver section. In the new Momentum M400, this stage has been elevated to a fully complementary design. There are now individual transistors employed for the positive and negative halves of the musical signal. This change nearly doubles the current drive necessary to maximize the enhanced output stage that follows. The new output stage takes this increased drive to boost the open loop gain by the same factor of two. The result is a sound that is more authoritative, richer, and more expansive. It is almost hard to believe that improvements could be made to the original Momentum amplifier after one reviewer said, “No component has had such a profound effect on me…” but Dan has done it!
The Momentum M400 employs the same chassis with a small aesthetic design change to the copper feature on the faceplate sides. Additionally, the meter now displays a scale appropriate for the greater output. With the Momentum M400, Dan has once again elevated the state of the art in amplifier design.
Full specfications and more information will be on the website soon.

The new S1 (Mk II) incorporates distilled elements of our most recent and groundbreaking engineering accomplishments which are found in the S7 loudspeaker. From a distance the new S1 (Mk II) appears similar to its predecessor, however upon closer inspection numerous improvements are easily recognized.
Detailed and extended high frequencies emanate from a newly designed Magico 1-inch Diamond coated Beryllium diaphragm tweeter that offers matching sensitivity, wide dispersion and high power handling. A robust motor system and long-throw voice coil design enables lower distortion and cutoff frequencies that enhance driver integration with the mid bass driver. Compelling mid-bass performance is generated by a newly designed 7-inch driver that incorporates the new Gen 7 Magico Nano-Tec cone material that was formulated for the MProject. The driver cone is formed from an ultra-stiff carbon material with a Graphene layer which provides a perfect ratio between weight, stiffness and damping. The voice coil is formed of pure titanium and the new motor features stronger neodymium magnets which enhance the magnetic field. The Magico tweeter and mid bass transducers are managed by a two-way dividing network which maximizes frequency bandwidth while preserving phase linearity and minimizes IM distortion. Individual driver performance and the loudspeaker in its final form are tested and optimized for acoustical, mechanical, electromagnetic and thermal behaviors using the latest state-of-the-art Finite Element Analysis simulation testing equipment. The monocoque enclosure of the S1 (Mk II) is formed from a single piece of extruded aluminum that is 3/8-inch thick and 12-inches in diameter. A massive new top plate is machined into an elegant 3D convex shape to minimize enclosure diffraction and break-up vertical standing waves. The thicker base plate incorporates a newly designed 4-point outrigger support that lowers the center of gravity and increases overall stability resulting in lower noise floor and increased dynamics. The new S1 (Mk II) is available a new M-Cast finish and the luxurious M-Coat painted finish. Specifications:

The new S5 (Mk II) incorporates distilled elements of our most recent and ground breaking engineering accomplishments which are found in the S7 loudspeaker. From a distance the new S5 (Mk II) appears similar to its predecessor however upon closer inspection numerous improvements are easily recognized. Detailed and extended high frequencies emanate from a newly designed Magico 1-inch Diamond coated Beryllium diaphragm tweeter that offers matching sensitivity, wide dispersion and high power handling. A robust motor system and long-throw voice coil design enables lower distortion and cutoff frequencies that enhance driver integration with the midrange driver.
The new midrange driver in the new S5 (Mk II) sets a new benchmark of measured performance. The cone material is formulated using Arkema Multi-Wall carbon nanotube and XG Sciences C750 Nanographene which combined is 20% lighter and 300% stiffer than previous cone material used in the original S5. The underhung neodymium base motor system uses two extra-large magnets which provide an ultra-stabilized magnetic field for the pure titanium voice coil to operate within. The driver operates in a purpose built sub-enclosure made of a proprietary polymer material that was first introduced in the S3. New Dual 10-inch bass drivers have extremely powerful magnets, with ultra-stiff aluminum cones that are specially coated and finished with graphene dust-caps. This new bass driver is capable of producing incredibly deep and powerful bass frequencies with the utmost speed and accuracy. The excursion rate of the voice coil is measured at 15-mm linear movement, twice as much as its predecessor, and produces clean and undistorted sound pressure levels up to 120dB @ 50Hz / 1-meter. The impressive enclosure of the S5 (Mk II) is formed from extruded aluminum, 1/2 inch thick and 16-inches in diameter. A massive new top plate is machined into an elegant 3D convex shape to minimize enclosure diffraction and break-up vertical standing waves. The thicker base plate incorporates a newly designed 4-point outrigger support that lowers the center of gravity and increases overall stability resulting in lower noise floor and increased dynamics. All five drivers in the new S5 (Mk II) are acoustically integrated using Magico’s exclusive Elliptical Symmetry Crossover topology that includes state-of-the-art components from Mundorf of Germany.
