Taiwanese company KECES has introduced the world’s first pre-amplifier equipped with a phono stage for optical cartridges from DS Audio. In addition, the new product is equipped with a conventional phono stage for working with moving magnet (MM) and moving coil (MC) heads.
The KECES S4 preamplifier uses a balanced circuit topology with zero feedback. Designed in a fully balanced concept, the S4 preamplifier offers a wide range of balanced (XLR) and unbalanced (RCA) inputs and corresponding outputs.
In addition, the KECES S4 preamplifier has a high-quality headphone amplifier, which can also be connected via a balanced interface. The device comes with an infrared remote control in a completely metal case.
