These dimensions provide flexibility, but there should be enough space available to allow for a trouble-free installation.
The gold-plated PCB of the Masterstroke MSK Class A ensures that electrical signals can be transmitted without interference and with minimal loss. The gold coating not only increases corrosion resistance but also improves electrical conductivity. This means that critical audio information can be transmitted precisely and without distortion from the input jack to the output. This design ensures that all the fine details of the audio recording arrive clearly and unaltered at the speakers.
The PRHESS - Primarily Regulated High-Efficiency Supply System in the Masterstroke MSK Class A ensures a constant and efficient energy distribution within the amplifier. This system minimizes fluctuations in the power supply that could lead to distortions and ensures consistent performance even with varying input voltage. Special emphasis is placed on maintaining uncompromising energy efficiency. This constant power supply not only guarantees a stable sound but also the dynamic musical reproduction, providing listeners with an unparalleled acoustic experience.
The low tolerance of the passive components in the Masterstroke MSK Class A means that the components have exact values, leading to consistent and precise sound reproduction. This accuracy ensures that all frequency ranges are amplified evenly and without distortion. Especially at high levels, this allows for the reproduction of fine nuances in both high and low tones. The balance between the left and right channels also remains stable, ensuring optimal stereo imaging. This precision is particularly relevant for listeners who want to experience music in a detailed manner.
The Masterstroke MSK Class A amplifier from STEG supports an input sensitivity of 0.4 V to 5.5 V, making it compatible with a variety of audio sources. This range allows the amplifier to accurately process signals from both high-quality sources and standard devices. Thus, it is versatile, whether you are using a high-end audio source or a regular car radio. This versatility in input sensitivity ensures that a clear and powerful sound is always guaranteed, regardless of the signal source used.
The highly efficient Class A regulation technology of the Masterstroke MSK Class A allows for the optimization of energy consumption by operating with high performance efficiency. This technology results in less energy being converted into heat, thereby avoiding unnecessary energy losses. It enables stable operation with minimal power consumption, which is particularly advantageous during longer listening experiences, as it leads to less strain on the vehicle battery. This achieves excellent sound quality without compromising on energy efficiency.

Features of the Masterstroke MSK Class A 2-channel amplifier from Steg

The Masterstroke MSK Class A impresses with first-class performance features that leave nothing to be desired. With an RMS output of 2 x 100 watts at 4 ohms, this amplifier demonstrates the true meaning of audiophile performance. Maximum power without compromise is guaranteed by operation at 2 ohms with 2 x 200 watts RMS. An ideal choice when it comes to dynamic sound quality in your vehicle. Unlike conventional 2-channel amplifiers, which are often undersized, the MSK Class A offers a rare blend of power and precision. Combined with Masori's lowest price guarantee, the amplifier clearly stands out from other products.

Advanced Class A technology in the Masterstroke MSK Class A

The Masterstroke MSK Class A sets new standards with its modern Class A technology. This technology, which has previously dominated the home hi-fi market, promises audiophile sound quality and a special warmth in the soundstage. In the automotive sector, Class A technology ensures unprecedented fidelity, as the constant activation of the transistors guarantees minimal distortion. Compared to conventional amplifiers, which often operate in the Class AB range, the MSK Class A stands out with its superior harmonization and detail. The sustained sound tuning, which the amplifier fulfills with first-class precision, is particularly noticeable in the mid-high range.

High-end preamplifier from Burr-Brown for maximum sound precision

A standout feature of the MSK Class A amplifier is its high-end preamplifier from Burr-Brown, which optimizes signal processing. This amplifier ensures accurate sound reproduction through the lowest possible distortion levels in every playback. In the car hi-fi world, Burr-Brown stands out as the undisputed champion for uncompromising sound fidelity, ensuring that every audio detail is reproduced precisely. Unlike standard preamplifiers, this one stands out with its recognized, more powerful signal processing, creating a deep and vibrant soundstage.

The unique SANK output transistors

Another technical highlight of the Masterstroke MSK Class A is the SANK output transistors. These not only offer unmatched stability under high loads, but also play a crucial role in the amplifier design, achieving excellent response across the entire frequency range. Compared to other transistors, SANK offers extended longevity and the ability to meet audiophile demands without compromise. The user-focused engineering makes this amplifier the ideal choice for discerning car audio enthusiasts.

Gold-plated PCB and transfer rails for optimal performance

The design implemented in the Masterstroke MSK Class A, with gold-plated PCBs and transfer rails, is more than just a visual treat. These materials optimize signal transmission and minimize resistance to maximize sonic fidelity. While many amplifiers rely on standard copper solutions, Steg goes the extra mile to ensure the best possible signal path quality without compromise. The result: unobstructed signal flow that maximizes pristine sound and minimizes unnecessary heat generation.

Efficient PRHESS supply and protection system

The innovative PRHESS (Primary Regulated High-Efficiency Supply System) amplifies the power of the Masterstroke MSK Class A with precise current regulation. This efficiency ensures a constant voltage, resulting in a stable sound and greater system stability. Conventional amplifiers often exhibit weaknesses in dynamic voltage ranges, but the MSK Class A's PRHESS ensures a stable current supply during every playback. This allows the system to glide smoothly through the performance requirements even with changing loads.

Noise reduction circuit and “INTELLISPEED” cooling system

The Masterstroke MSK's Class A noise reduction circuitry is striking, efficiently minimizing background noise. This allows you to enjoy crystal-clear sound even in acoustically challenging environments. This system is complemented by INTELLISPEED, a smart cooling system that uses integrated sensors to ensure constant cooling. This not only continuously extends the amplifier's lifespan but also optimizes its performance through real-time temperature adjustment.

Dimensions and structure of the 2-channel amplifier

Practical dimensions of 466 x 60 x 255 mm and a total weight of 7 kg make the Masterstroke MSK Class A ideal for installation in the trunk or under seats.
