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.

Based on a unique all discrete FET topology, 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.

Stellar Phono 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.

When PS engineer Darren Myers set his sights on building the best phono stage our company has ever produced, he had his work cut out for him. With the advantage of modern upgraded FET semiconductors and a fresh approach to the art of phono preamplification at his side, Darren wiped the tradition slate clean by hand-fashioning a new approach to the challenge of amplifying and preserving 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. What you hear fills the room with a rich tonality that has always been vinyl’s promise, but rarely fulfilled to the degree Stellar has achieved.

Stellar phono features dual inputs that can support either a moving coil or moving magnet cartridge, or a two-tonearm set up to enjoy the best of each at the user’s discretion. Cartridge loading and gain options are easily adjusted from your listening position via the supplied remote control.

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.

If you love vinyl you’ll love Stellar.
