The Stellar™ Strata™ combines the benefits of an exceptional analog preamplifier, a full-featured state-of-the-art DAC, a stereo 150 watt per channel power amplifier, and a high-performance streaming module in one gorgeous package. Strata's fully balanced analog preamplifier circuitry, state-of-the-art DAC, no compromise high-definition streamer, and Analog Cell™ based power amplifier create an extraordinarily rich, full-bodied musical experience few products can match. The Stellar Strata is the perfect foundation for those unwilling to compromise sound quality. Rich. Lush. Powerful. A music lover's answer to spiraling cost-no-object equipment without sacrifice.

The idea of combining a cutting edge DAC, full-featured analog preamplifier, high-definition streaming module, and a robust 200 watt per channel power amplifier was the basis of the Stellar Strata™ design imperative. PS Audio wanted an easy, simple, no-compromise musical experience whether streaming high-resolution audio from Tidal or exploring the millions of choices on Spotify, or plugging into a Stellar Phono. Strata holds true to its promise of easy connectivity. Download the PS Connect app onto your mobile device, point Strata to your home WIFI network, connect your speakers or headphones, and music filled with the rich textures and toe-tapping energy you've always hoped for will delight even the most critical music lover.

Audiophiles have long recognized the challenge of interconnecting multiple systems into a single synergistic musical experience. Interconnect choices, power supply options, and chassis isolation requirements all play into the building of a truly musical system - get any one part wrong and the system performance is compromised. Not so with Stellar Strata. The chance for PS Engineering to optimize the audio synergy between Strata's four separate systems was immediately appealing: eliminate the variability of interconnection issues, voice the entire system as one component, optimize power supplies, control every aspect of sound quality up to the speakers.
