Den nye Stellar™ Strata MK2™ kombinerer fordelene ved en enestående analog forforstærker, en fuldt udstyret state-of-the-art DAC, en stereo 150-watt pr. kanal effektforstærker og et fantastisk lydende MC/MM phono-trin i én smuk pakke.
Strata MK2's fuldt afbalancerede analoge forforstærkerkredsløb, state-of-the-art DAC, kompromisløs high-definition phono-stage og Analog Cell-baseret™ effektforstærker skaber en ekstraordinær rig, fyldig musikalsk oplevelse, som få produkter kan matche.
Stellar Strata MK2 er det perfekte fundament for dem, der ikke er villige til at gå på kompromis med lydkvaliteten. Rig. Frodig. Stærk. En musikelskers svar på spiralen af udstyr uden omkostninger uden at ofre.
The idea of combining a cutting edge DAC, full-featured analog preamplifier, high-definition streaming module, 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 streaming high-resolution audio or exploring the millions of choices on Spotify, or plugging into a Stellar Phono. "Just add speakers" became engineering's rallying cry. 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.
Application
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.
Technology
At this instrument's heart is the analog GainCell™. Developed by PS Audio founder Paul McGowan, the Gain Cell™ elegantly solves the fundamental problem facing preamp designers. Volume control. Nearly all analog preamplifiers use sonically-degrading elements inserted in the signal path to control volume. The Gain Cell eliminates this problem without additional circuitry in the signal path by varying its gain in response to front panel controls. Once the high definition streaming module or connected source has passed through the Class A analog preamplifier, it's time to connect to your speakers. Here, engineer Darren Myers used the Analog Cell where he could lavish upon the music the sweet, tube-like quality of Class A biased MOSFETs. Combined with the ruler flat high linearity of Strata's high current output stage, richly overlayed layers of music’s inner details are preserved even in the most complex orchestral crescendos.
