INFORMATION
The PHS-SR is our Reference all-solid-state phono preamplifier, specially designed and voiced for the most enthusiastic vinyl-loving audiophiles who prefer uncolored tonality, excellent detail retrieval and dynamics, combined with harmonically rich and effortless sound reproduction.
It is an all-hand-made exclusive design, in the best tradition of boutique manufacturing, built for the best possible vinyl playback audio quality.
The first hybrid phonostage we built more than 10 years ago was extremely well received by vinyl enthusiasts around the San Francisco Bay Area.
The PHS-SR topology has been carefully chosen and further refined through the years combined with endless experiments, resulting in a design that does not use vacuum tubes, but lacks the analytical qualities often associated with a solid-state sonic character.
The achieved audio reproduction quality will surprise both tube and solid-state fans with a very live-like natural and neutral presentation that cannot be attributed to the usual sonic signature of tubes or transistors.
