Description

The Stellar M1200 monoblock power amplifier combines the rich warmth and musicality of vacuum tubes with the jaw-dropping power and seemingly infinite headroom of a 1200 watt high-performance output stage. This extraordinary hybrid amplifier knows no limits. From the subtlest musical whisperings to the loudest crescendos an orchestra or rock band is capable of, Stellar M1200 never flinches. Regardless of your speaker’s power demands or limitations, enjoy the once unachievable uncompressed effortlessness afforded by this design. Pure musical bliss for any loudspeaker made, from the smallest to the biggest. Stellar.

The M1200 began as the dream project of PS engineer, Darren Myers who wanted to build a power amplifier without bounds or compression on even the loudest of musical passages, yet equally at home reproducing the subtlest of details.

To preserve both uncompressed dynamics as well as the tiniest of nuanced details requires a cost-no-object input stage, like that of a high-performance vacuum tube fed from its own analog power supply. The amp’s delicate input signals, now faithfully preserved by its vacuum tube input, then need to be amplified without restriction by taking advantage of a new type of Class D output power module. This extraordinarily high current, low distortion, MOSFET output stage combines state-of-the-art topologies with decades of design and listening experience to produce what we believe is the most musically satisfying amplifier of its kind.

The over-the-top high power output of the M1200 exists not to match a small handful of power-hungry speakers, but rather, to act as the perfect uncompressed power source for even the smallest, most efficient of speakers on the market.

Remember, power amplifiers deliver only the number of watts required by your speaker to achieve the desired loudness. Even the most powerful amplifiers deliver only what’s asked of them. What’s been missing in most amplifiers is adequate headroom and effortless linear performance—something only a vacuum tube-based powerhouse like the M1200 can unquestionably provide. From the most subtle of details to unheard of explosive dynamics, Stellar M1200 represents the pinnacle of high powered musicality that must be heard to be believed. Regardless of the power demands—or power limitations—of your loudspeakers, Stellar M1200 is the perfect choice if effortless musicality is in your future.
