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 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.
