Zoom Audio Labs L1
L1 is fixed input load MM phono preamp with JFET discrete input stage. JFET is most similar semiconductor to the vacuum tube, and as we have small signals – they can provide even higher performance compare to vacuum tubes, which are mainly designed for larger signals amplification. By applying specially developed schematic we were able to get tube like full and rich sound, yet maintaining highly dynamic, detailed, low noise performance typical to semiconductors.
Current lineup consists of two phono preamplifiers. One is for MM input cartages, and other one is for MC cartages. Both of them internally are quite similar, and top quality components are used to get lowest possible noise and highest RIAA curve accuracy. But as always we don’t stop at performance part, we also listen to the product. So both of these phono preamps are tuned to vacuum tube sound signature, meaning that as power amplifiers they have that warm, but yet highly dynamic and precise sound.
