The S300 combines the slam, linearity, and toe-tapping pacing of a Class D output stage with the warmth, grace, and rich inner detail of Stellar’s Class A Analog Cell. The results are nothing short of ground breaking. Liberate a wealth of untapped energy trapped in your media library. Plumb music’s subterranean depths and finally hear the bass your speakers were capable of. Revel in rich layers of fine, full detail. Marvel at the deep, extraordinary, wall-to-wall soundstage. Effortless. Lush. Stellar.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDESIGN\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Stellar S300 stereo power amplifier is a dual mono power amplifier capable of effortlessly driving demanding loudspeaker loads to concert levels. It 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 S300’s rich, warm, and engaging sonic character comes from the Analog Cell. It’s powerful, authoritative control over the loudspeaker stems from its high current, ultra-low impedance Class D output stage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAPPLICATION\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe perfect choice for just about any loudspeaker, the S300 slips into any system, surprising and delighting even the most discriminating Audiophile. Rated at 140 watts per channel into 8‎Ω and 300 watts per channel into 4‎Ω, the S300 has plenty of horsepower for even the most demanding loudspeakers. Your musical library will open up in ways you might not have thought possible, revealing nuance and detail covered up by traditional amplifiers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnology\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOVERVIEW\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe S300 is an extraordinarily musical power amplifier rated at 140 Watts per channel into 8Ω and 300 Watts per channel into 4Ω. Power enough for even the most demanding speakers. The S300 design marries the best of two worlds: an ultra linear high-current output power stage with a discrete Class A MOSFET based AnalogCell input stage. Between them, the S300 delivers powerful, authoritative control over the loudspeakers, while maintaining a perfectly layered soundstage under the most complex musical passages. Designed by PS Audio engineer Darren Myers, who invested hundreds of hours of tuning, voicing, and perfectionist tweaking, the results are extraordinarily musical. Stellar amplifiers never draw attention to themselves, and are one of our highest value offerings in amplification, a rare quality in amplifiers of any price.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHE ANALOG CELL\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe connection between preamplifier and power amplifier is critical, for it is at this junction where most essential musical details are easily lost. Nothing in the design of a power amplifier is more important than its input stage when preserving music’s finest nuances. In the S300, a unique topology, called the Analog Cell, has been employed to preserve the rich details found in music. The Analog Cell is the heart of the S300’s musicality, where rich overlaid layers of music’s inner details are preserved even in the most complex orchestral crescendos. The Analog Cell is 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 Analog Cell makes all the difference.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOUTPUT STAGE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Stellar S300 is a dual mono design. This means that each channel has its own, separate power supply. Each of the two channels is a complete and independent power supply and power amplification stage, based on a modern Class D ICE module, designed in Denmark. Class D output stages provide near-perfect linearity, low distortion, and high efficiency. Because Class D amplifiers require an output filter to remove their switching noise, they do not have frequency extremes into the many hundreds of thousands of Hertz. Depending on their design, 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. The S300 provides excellent frequency extremes, low distortion, high efficiency, high damping factor, and a powerful output of 300 watts per channel into the most common loudspeaker loads of 4Ω.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSTEREO POWER AMPLIFIER\u003c\/li\u003e\n\u003cli\u003eDUAL MONO WITH SEPARATE POWER SUPPLIES\u003c\/li\u003e\n\u003cli\u003ePOWERFUL MOSFET OUTPUT STAGE\u003c\/li\u003e\n\u003cli\u003eRCA SINGLE-ENDED INPUT\u003c\/li\u003e\n\u003cli\u003eXLR “TRUE” BALANCED INPUT\u003c\/li\u003e\n\u003cli\u003e140 WATTS PER CHANNEL 8Ω\u003c\/li\u003e\n\u003cli\u003e300 WATTS PER CHANNEL 4Ω\u003c\/li\u003e\n\u003cli\u003e2Ω STABLE\u003c\/li\u003e\n\u003cli\u003eVERY LITTLE HEAT PRODUCTION\u003c\/li\u003e\n\u003cli\u003e\u0026lt; 0.1% THD 20Hz – 20kHz AT RATED POWER\u003c\/li\u003e\n\u003cli\u003eDAMPING FACTOR \u0026gt; 550\u003c\/li\u003e\n\u003cli\u003eFRONT PANEL STANDBY BUTTON\u003c\/li\u003e\n\u003cli\u003eZERO-LOSS INPUT\u003c\/li\u003e\n\u003cli\u003eDUAL, COPPER, PLATED, OUTPUT BINDING POSTS\u003c\/li\u003e\n\u003cli\u003e13 LBS.\u003c\/li\u003e\n\u003cli\u003eINPUT 12 VOLT TRIGGER\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eReviews\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe result of all these strengths gives the S300 a beautiful voice which mates well with the variety of upstream gear we had on hand for testing.

We have heard vast improvements of Class D amplifiers during the last 10 years, and we are at or near the point where the technology is largely irrelevant to the final sound. The sound of audio components is more dependent on the implementation than on the underlying technology.
