The line tube type line level preamplifier developed by collecting the know-how of unison research. It features a glossy and gentle tone that is typical of Unison Research. Simply-Phono (sold separately) is an attractive set for analog fans. By combining Italian speakers, as well as European speakers such as those made in the UK, we provide a comfortable listening sound. All stages are pure A-class vacuum tube circuits, eliminating semiconductor elements from all electronic circuits involved in amplification. A fixed bias by a lithium battery is adopted for the first-stage tube, and a stable and optimal bias is always given to ensure high linearity and low noise. Furthermore, the input selector uses a gold contact relay filled with nitrogen gas. As an option, the SIMPLY PHONO pre-amplifier for MM-type phono cartridges developed for the Simply series and MISTERO input impedance is switchable. The power supply is designed to be supplied from the Simply series or MISTERO with a dedicated DIN terminal. *This product is a set. ?Power cord. *There are scratches and stains. *Input terminals: CD, AV, Tuner, Aux/Phono. *Sold separately with optional SIMPL PHONO. * Pre-preamp for MM-type phono cartridges developed for the Simply series and MISTERO Input impedance is switchable.
