The PS Audio Strata MK2 Integrated Amplifier 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 an amazing sounding MC/MM phono stage in one gorgeous package. Strata MK2's fully balanced analog preamplifier circuitry, state-of-the-art DAC, no compromise high-definition phono stage, and Analog Cell™ based power amplifier create an extraordinarily rich, full-bodied musical experience few products can match. The Stellar Strata MK2 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.
Combining a cutting-edge DAC, full-featured analog preamplifier, high-definition MC/MM phono preamplifier, and a robust 150-watt per channel power amplifier was the basis of the Stellar Strata™ design imperative. We wanted an easy, simple, no-compromise musical experience, whether playing from a connected transport or tracking amazing vinyl. "Just add speakers" became engineering's rallying cry. Strata MK2 holds true to its promise of audiophile plug-and-play. Connect your speakers or headphones, press play, or lower the needle onto your vinyl, and music filled with the rich textures and toe-tapping energy you've always hoped for will delight even the most critical music lover.
