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.
If you've always dreamed about anchoring your system with a pair of authoritative monoblock amplifiers that effortlessly drive practically any speaker on the planet but never believed you could afford them, the PS Audio Stellar M700 amps are made for you. Hand-built, made-in-the-U.S.A., full-size, and dual-mono in construction, Stellar M700 sound tremendously natural, detailed, musical, and open. They provide mind-boggling grip, depth, and control courtesy of 340Wpc into eight ohms and a whopping 700Wpc into four ohms. Combining slam, linearity, and pacing with grace, richness, and warmth, Stellar M700 constitute a new kind of hybrid steeped in traditional and modern technologies. Designed by Darren Myers, they utilize 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 M700 deliver bold results that components at their price point have no right to offer. You'll love their spacious, effortless, dynamic presentation, mammoth headroom, non-aggressive character, subterranean bottom end, fantastic soundstaging, and extreme energy. 100% Music Direct Guaranteed.
The secret to Stellar M700's price-to-performance-busting abilities resides with their 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, M700 preserve 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, M700 tout marvelous pacing, glare-free playback, and control over even very complex passages. Let's not forget M700 are built by hand in Colorado. No cheap Chinese manufacturing or third-party parts here. PS Audio has thrown down the gauntlet with M700 – a pair of monoblocks entirely deserving of their Stellar badge.
Analog Cell Topology Preserves Details, Nuances, and Richness
The connection between preamplifier and power amplifier is the junction where most essential musical details are easily lost. When it comes to preserving music's finest nuances, nothing in a power amplifier is more important than its input stages. In M700, Analog Cell topology is employed to preserve music's rich details. Long hours of listening and tuning sessions in Music Room One, shared by PS Audio founder Paul McGowan and designer Darren Myers, resulted in a sonic signature that honors the music and never draws attention to itself.
Dual-Mono Design with Separate Independent Power Supplies
Stellar M700 employ a dual mono design, meaning each channel in each amp 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. Class D output stages' strengths are many: Near-perfect linearity, low distortion, high efficiency. Stellar M700 provide excellent frequency extremes, low distortion, high damping factor, and a staggeringly powerful output of 700Wpc into the most common loudspeaker loads of four ohms.
