Description
PS Audio Stellar Phono Preamplifier
Designing the PS Audio Stellar Phono Preamplifier, PS engineer Darren Myers wiped the tradition slate clean by hand-fashioning a new approach to capturing all the magic trapped in the grooves of our records. The results are breathtaking. Music that might once have been locked into the confines of our loudspeakers is suddenly free. Stellar Phono Preamplifier features dual inputs that can support either a moving coil or moving magnet cartridge. Cartridge loading and gain options are easily adjusted from your listening position via the supplied remote control. Input to output, Stellar Phono Preamplifier is a fully discrete FET design with extraordinarily low noise and high overload capabilities so even the wildest dynamics from the punchiest cartridges sail through Stellar with no limitations or compromise whatsoever. If you love vinyl you’ll love Stellar Phono Preamplifier.
- DESIGN – Phono preamplifiers at anywhere near this price range are almost always integrated circuit based, but not Stellar. Input to output, Stellar is a fully discrete FET design with extraordinarily low noise and high overload capabilities so even the wildest dynamics from the punchiest cartridges sail through Stellar with no limitations or compromise whatsoever. Stellar Phono stands out in a crowded field of conventional IC designs. Its sound is rich, warm and enticing as only vinyl through hand-tuned class-A circuitry can be.
- APPLICATION – Stellar Phono Preamplifier is the perfect phono preamplifier for any resolution system or cartridge type. From the lowest output moving coil to the most dynamic and punchy moving magnet, Stellar Phono will deliver incredible performance, low noise, and world class sonics. Use Stellar as your reference preamplifier in the highest end systems in the world. Stellar comes complete with remote control so users can select between two turntables, or adjust cartridge loading and gain settings from the comfort of their chairs.

Technology
PS Audio’s first product was a phono preamplifier that took the Hi-Fi world by storm in 1975. Its designers, Paul and Stan, labored for years over every circuit detail with one goal in mind—making musical magic. Stellar Phono shares that same ethos. Stellar Phono Preamplifier is the finest preamplifier PS Audio has ever built in its 45 year history and sets a new standard within the industry. It is a triumph of performance and value that you’ll instantly recognize from that first needle drop, as music emerges from a velvet blackness, filling the room as if there were no speakers. Stellar handles all cartridge types and employs no ICs in the signal path. Its all discrete, class A analog design produces over 20V rms output for unparalleled headroom and dynamics.
The Inside Scoop
The art of design is a careful balance between the measurement lab and the listening room. The hundreds of hours of design and audition resulted in a unique amalgam of time honored technology coupled with daring innovation. Stellar Phono Preamplifier is an all discrete FET design that uses a passive RIAA curve, hand selected premium components, and is direct coupled from input to output. Its ultra low noise discrete pre and post voltage regulation stages, coupled with low internal feedback, offer increased transparency and openness rarely found in instruments anywhere near this price.
Construction
When you first pick up Stellar Phono Preamplifier you’ll notice its solid build and heft. Every inch of Stellar suggests quality: from its rear panel connectors, cartridge loading facilities, to its internal high current oversized power transformer. The internal shielding and build quality provide Stellar with up to 70dB of ultra low noise gain for MC cartridges as low as 0.15mv. On its rear panel find facilities for two inputs for two tonearms selectable from remote control, as well as both single ended and balanced outputs to match any preamplifier.
