Dan D'Agostino Master Audio Systems LLC. presents D'Agostino Momentum C4 Preamplifier

With the new D'Agostino Momentum C4 Preamplifier, the US High-end HiFi manufacturer Dan D'Agostino Master Audio Systems LLC. is expanding its product range in the D'Agostino Momentum Series with another solution - an outstanding preamplifier, as promised by the manufacturer.

Story Highlights
  • At the High End 2024, the US High-end HiFi manufacturer Dan D'Agostino Master Audio Systems LLC. presented the new D'Agostino Momentum C4 Preamplifier.

The US high-end HiFi manufacturer Dan D’Agostino Master Audio Systems recently surprised everyone with a very special product presentation at the High End 2024 in Munich. The latest solution in the Dan D’Agostino Momentum Series was presented for the first time, namely a preamplifier that promises very special features, the D’Agostino Momentum C4 Preamplifier.

The D’Agostino Momentum C4 Preamplifier is equipped with all the proven virtues that characterise the D’Agostino Momentum Series solutions as a whole. It is handcrafted in Cave Creek, Arizona, and the manufacturer is convinced that it will outperform even the D’Agostino Momentum HD Preamplifier.

Sound perfection through and technological innovation

The new D’Agostino Momentum C4 Preamplifier has been developed from scratch, according to company founder Dan D’Agostino during the presentation at High-end 2024 in Munich.

Not only has all the decades of experience been incorporated, but the latest technological innovations have also been used to achieve a completely new level of quality, as the legendary developer puts it.

D’Agostino Complementary Four Circuit Topology

The basis of the new D’Agostino Momentum C4 Preamplifier is the revolutionary D’Agostino Complementary Four Circuit Topology, simply abbreviated as C4, which is also reflected in the name of the preamplifier.

This unique circuitry of the input stage sets a new standard for performance and precision and provides the basis for an incomparably clear and unadulterated sound experience, as the manufacturer promises.

Building on the heritage of the Dan D’Agostino Momentum HD preamplifier, the new Dan D’Agostino Momentum C4 topology utilises an array of four JFET transistors in a complementary, differential push-pull arrangement that dramatically increases input impedance and reduces noise for exceptional performance and stability in any system configuration.

Outsourced power supply unit

To ensure the best possible signal processing free from sound-damaging influences and the highest possible performance, the power supply unit of this preamp has been outsourced, with the actual preamp ultimately sitting enthroned on this power supply unit. The connection is made via a special plug connection.

Flexible configuration

Naturally, the new Dan D’Agostino Momentum Series preamplifier offers a range of connections to act as a flexible interface. There is not only one unbalanced analogue input in the form of a pair of RCA sockets, but also three balanced inputs in the form of XLR connectors. In terms of outputs, this solution offers a pair of XLRs for balanced signal transmission to the power amplifier.

It should also be mentioned that the user can intervene via Tone Control if desired and a headphone amplifier is also available, which is based on an independent circuit.

Optional DSM digital streaming module

The D’Agostino Momentum C4 Preamplifier can be upgraded with a digital streaming module if required. The digital extension offers connection options for a wide variety of sources, in addition to a USB-A port for direct connection to a PC or Mac, S/PDIF coaxial and S/PDIF optical are available here, and the system can be integrated into the network via an RJ45 Gigabit Ethernet interface as well as via WiFi, so that streaming is also possible. A special D’Agostino DSM app for Apple iOS provides access to Spotify, TIDAL, Qobuz and other services. The signal processing allows data in Linear PCM with up to 32 bit and 384 kHz as well as DSD up to DSD512 and content encoded in lossy MQA is also supported. The DSM is also specified for TIDAL Connect and is said to be Roon Ready.

As has long been customary with solutions from Dan D’Agostino Master Audio Systems LLC., the new D’Agostino Momentum C4 preamplifier also offers particularly elegant control, both via numerous operating elements directly on the front of the device and via the associated bidirectional remote control, which presents itself as a masterpiece of precision engineering. Like the housing of the preamplifier, it is also CNC-machined from aluminium and copper and has an LCD screen that corresponds to the display on the front of the preamplifier and copies it one-to-one.

Finally, it should be mentioned that the new D’Agostino Momentum C4 Preamplifier measures 43,2 x 22,6 x 38,6 cm and thus weighs 33,1 kg. It is available in either silver or black.

Prices and availability

It is not yet clear when and at what price the new preamplifier will be available in this country. In any case, a price of US$ 50.000,- is quoted for the USA, with delivery expected in July 2024.

Getting to the point

The new D’Agostino Momentum C4 Preamplifier is a preamplifier that can once again outperform the Dan D’Agostino Momentum HD Preamplifier, as promised by US High-end HiFi manufacturer Dan D’Agostino Master Audio Systems LLC. at the presentation of this D’Agostino Momentum Series solution at the High End 2024 in Munich.
