Opis s interneta:
Based on two 6N16 vacuum tubes, the SA-31 is a linestage preamplifier that provides four analog inputs, two analog outputs, a recording output, and two old-school features—namely, a loudness compensation circuit and switch-selectable tone controls. Purists might counsel against using EQ for any reason, but I think there are contexts where the loudness function can improve perceived tonal balance for low-volume listening. Similarly, Vincent’s tone controls are subtle enough that they could be used, judiciously of course, to correct minor tonal imbalances in less-than-ideal recordings. Sadly, one modern feature the SA-31 does not provide is a remote control—an omission I came to regret as I made my umpteenth trip across the listening room to tweak volume levels. One very well-thought-out detail is the SA-31’s power-on muting circuit, which engages when the unit is fired up, as denoted by the power light flashing on and off, and releases once tubes are warmed up and the preamp is ready to play music.
The SA-31 produces a rich, seductive sound, whose signature characteristic is a midrange that is dynamically alive and leans just slightly to the warm side of neutral. Together, these qualities help the preamp do a fine job of capturing subtle contours or inflections in both human and instrumental voices. For example, in the opening of “Casi” from Marta Gómez’s Entre Cada Palabra [Chesky] the SA-31 shows great delicacy as it captures the very soft, gently modulated sound of Gómez’s voice accompanied by a bass guitar that deliberately plays only high harmonics sans bass fundamentals. The preamp shows how the singer’s voice remains pure, steady, and clear, even though Gómez is singing at little more than a whisper level, and also draws out the ringing sound of the bass harmonics, which fill the recording space with an almost gamelan-like sound.
