PS Audio's fully balanced Stellar Gain Cell DAC marries a DSD-capable DAC with a complete analog preamplifier control center in a U.S.-built high-end component whose affordable cost belies its full suite of functions, features, and performance. Based on an upgraded version of PS Audio's NuWave DSD, and anchored by a 32-bit ESS Sabre Hyperstream DAC with passive analog filtering, Gain Cell accepts inputs from any digital source – including I²S and USB from computers. Able to asynchronously handle 24-bit/192kHz PCM and up to 2x DSD, Gain Cell doubles as a high-resolution server when paired with a USB cable and computer, operated with server software like JRiver, and controlled via a smart device. Every signal is accepted in native mode and without sample-rate conversion, then fed into a Complex Programmable Logic Device (CPLD) that utilizes proprietary Digital Lens technology to reclock the data, reduce jitter, and diminish propagation delay. Three digital filters provide even more options and flexibility with your current – and future – components. In laymen's terms: Gain Cell makes music sound incredibly three-dimensional, spacious, rich, and lively.
Gain Cell's analog preamplifier section matches the build and character of the DAC in every way via high-grade parts and boasting a novel solution to the classic volume-control problems associated with all preamps. Instead of inserting an additional level control in the signal path, variable gain cell topology lets the preamplifier's actual amplifier stage vary its gain in response to the user's front-panel volume control. This method requires no additional circuitry in the signal path and offers more than 80dB of attenuation. What's more, Gain Cell touts 100% analog input switching in the DAC so that no matter from where the signals emanate, be it the DAC or an external phono preamp, they are fully preserved and sacrifice nothing in translation. Balanced and single-ended outputs, a headphone amplifier, and a remote control round out a piece that is nothing short of Stellar. 100% Music Direct Guaranteed.
A hand-built, made-in-the-U.S.A., full-size, under-$1,500, dual-mono power amplifier able to authoritatively drive most loudspeakers to their peak potential all the while sounding natural, musical, and rich? PS Audio's Stellar S300 stereo power amp is all and that and more. Outputting 140Wpc into eight ohms and a whopping 300Wpc into four ohms, Stellar S300 is a new kind of hybrid steeped in traditional and modern technologies. Designed by Darren Myers, it utilizes ultra-linear, high-current Class D operation for the output stage and a discrete, Class A MOSFET-based Analog Cell for the crucial input stage. Stellar S300 delivers sonic results that compete with many components selling for more than three times its price. You'll love the spacious, warm, effortless, dynamic presentation, unearthed nuances, and non-aggressive character. 100% Music Direct Guaranteed.
The secret to Stellar S300's price-to-performance-busting abilities resides with its Analog Cell topology that provides a zero-loss interface between the preamp and DAC. A zero-feedback, balanced, Class A, MOSFET input stage, it closely mirrors the sonic properties of a vacuum tube and conveys music with utmost faithfulness. Carefully voiced by Meyers, Stellar S300 preserves the key details, subtle cues, soundstage dimensions, and instrumental overtones many amplifiers fail to retain. These are the very traits necessary for engaging, emotional connections to your favorite records. Just as important, S300 touts marvelous pacing, glare-free playback, and control over even very complex passages. Let's not forget Stellar S300 is built by hand in Colorado. No cheap Chinese manufacturing or third-party parts here. PS Audio has thrown down the gauntlet with S300 – a component entirely deserving of its Stellar badge.
