Ps audio stellar m1200 power amplifier - black

The Stellar M1200 mono amplifiers are high-power, super-linear, tube-input amplifiers that deliver uncompressed performance.

The Stellar M1200 mono amplifier combines the warmth and musicality of tubes with the astonishing power and seemingly endless power reserves of a high-performance 1200-watt output stage. This extraordinary hybrid amplifier knows no bounds. From the most delicate musical whispers to the thunderous crescendos of an orchestra or rock band, the Stellar M1200 never falters. Regardless of the power demands or limitations of your speakers, enjoy the natural, uncompressed purity and clarity this design offers, once unattainable. Pure musical ecstasy for any speaker, from the smallest to the largest. Stellar.

Design

To preserve both uncompressed dynamics and the finest nuances, an uncompromising input stage is required, such as that of a high-performance vacuum tube. The amplifier's delicate input signals, now faithfully preserved by the vacuum tube input, must then be amplified without restriction using a new type of Class D power module. This remarkably high-current, low-distortion MOSFET output stage combines cutting-edge topologies with decades of design and listening experience to produce what we believe to be the most musically satisfying amplifier in its class.

Application

Power amplifiers deliver only the wattage needed by speakers to reach the desired volume level. Even the most powerful amplifiers deliver only what is asked of them. What most amplifiers lack is adequate power headroom and effortless, linear response—characteristics that only a tube amplifier like the M1200 can unmistakably deliver. From the subtlest details to the most astonishing explosive dynamics, the Stellar M1200 represents the pinnacle of high-power musicality, an experience that has to be heard to be believed. Regardless of the power needs, or power limitations, of your speakers, the Stellar M1200 is the perfect choice if you desire effortless musicality.

Overview

The Stellar M1200 mono amplifiers solve a classic problem that plagues nearly all power amplifiers: compression. When the orchestra gets louder and more complex, or when the band starts playing with gusto, most power amplifiers leave their comfort zone, and the sound suffers, manifesting as compression. The M1200 is designed to reproduce any music on any speaker without any compression. Rated at 600 watts into 8Ω and a whopping 1200 watts into 4Ω, the M1200 combines the best of two worlds: ultra-linear, high-current ICE Edge Class-D technology for the output stage and a discrete Class-A vacuum tube for the all-important input stage. The M1200's rich, warm, and nuanced musical reproduction comes first from its feedback-free, Class-A vacuum tube input stage. Here, nothing is lost thanks to the hand-selected 12AU7 vacuum tube, powered by its own analog power supply.

The Vacuum Tube Input

The power amplifier is a technology that is ever-present in stereo systems. Yet despite its ubiquitous nature, few appreciate its crucial role in preserving musical nuance, as most amplifiers fail to do so. Harmonics of plucked instruments, subtle cues that define the position, depth, and breadth of the soundstage, and the decay of transients, are often lost in a power amplifier. The M1200 loses none of this thanks to its all-tube input stage. In the M1200, a feedback-free, Class A tube input stage captures every musical detail, preserving the most dynamic crescendos and fast-rising transients intact, without any loss. The listening experience with the M1200 is nothing short of revelatory. While most amplifiers strive to preserve dynamics, they fail to reproduce them as if they were live. The M1200 eliminates the tendency of almost all power amplifiers to change their sonic character as the volume increases.

Output Stage

The Stellar M1200 features a massive power supply and a high-power, ultra-linear amplifier stage based on a modern Class-D ICE module. The Class-D output stages offer near-perfect linearity, low distortion, and high efficiency. Modern Class-D amplifiers, like the one used in the Stellar, extend high frequencies up to approximately 50 kHz. The limit of human hearing is 20 kHz, although most listeners rarely exceed this value. Thanks to its excellent frequency response, low distortion, high efficiency, high damping factor, and a generous and powerful 1200 watts of power into the most common 4Ω speaker loads, the M1200 is simply breathtaking. The extraordinary power of the M1200 fits perfectly into any speaker, large or small, offering enormous power reserves and impeccable sound quality for even the most demanding orchestral crescendos.
