Design

The hybrid approach used in the Stellar M700 Power Amplifier takes advantage of the best traits technology has to offer. The perfected analog voltage is then converted into the high current output needed to effortlessly drive your loudspeakers.

Applications

The M700 is Stellar's best. Rated at 350 watts into 8Ω and 700 watts into 4Ω, a pair of these placed on any loudspeaker brings forth the lush, rich, and soul-satisfying power of two completely independent power blocks with headroom to spare. The listening experience with the M700 starts feet tapping and smiles breaking out. One listen to a hugely loud and complex musical passage effortlessly rendered by the M700 pair and you'll know you made the right choice.

Overview

Rated at 350 Watts into 8Ω and 700 Watts into 4Ω, the M700 combines the best of two worlds: ultra linear, high-current, Class D technology for the output stage; a discrete, Class A MOSFET based Analog Cell for the all-important input stage. The Stellar M700 captures the rich, full-bodied essence of recorded music and presents it to your loudspeakers with authority and grace, never a hint of glare or unnaturalness. The M700 is faithful to the music like few amplifiers are. Listeners are constantly surprised at the width and depth of the M700's soundstage; its preservation of the smallest details in reverb, room acoustics, and musical overtones; its commanding presence without intrusion; its delicate handling of subtle shadings; its authority as it grabs hold of the loudspeaker and breezes through even the most complex musical passages.

The Analog Cell

Stellar's design imperatives -- affordable pricing and uncompromised sonics -- were major challenges solved by the invention of a unique new circuit christened the AnalogCell. Nothing in the design of a power amplifier is more important than its input stage when preserving music's finest nuances. Knowing full well that the input stage determines sonic character, the AnalogCell has been employed to preserve the rich details found in music. The AnalogCell is the heart of the M700's musicality, where rich overlaid layers of music's inner details are preserved even in the most complex orchestral crescendos. As a proprietary, fully differential, zero feedback, discrete, Class A MOSFET circuit, hand-tuned to capture the smallest micro dynamics without sacrificing the loudest macro dynamics music has to offer, the AnalogCell makes all the difference in preserving music's magic.

Output Stage

The Stellar M700 has a massive power supply and ultra-linear, high-wattage power amplification stage based on a modern Class D ICE module. Class D output stages provide near-perfect linearity, low distortion, and high efficiency. Modern Class D amplifiers, like the type used in Stellar, extend high frequencies to about 50kHz. Human hearing limitations are 20kHz, though most listeners rarely have hearing exceeding half that. Providing excellent frequency extremes, low distortion, high efficiency, high damping factor, and a generous and powerful output of 700 watts into the most common loudspeaker loads of 4Ω, the M700 is nothing short of breathtaking. The massively powerful nature of the M700 works well with any loudspeaker—big or small—providing huge amounts of headroom and effortless sound quality for even the most demanding orchestral crescendos.
