Electrostatic type First step for beginners Successor to the long-selling system ●SR-X1 + SRM-270S (Newly developed driver unit exclusively for set models) The SRS-X1000 is a set that combines the SR-X1 with the newly developed small driver unit SRM-270S. The SRM-270S features updated designs from the previous model (SRM-252S), including higher-quality RCA pin jacks, a 3mm thick front aluminum panel, and a larger extruded aluminum case with improved heat dissipation. The first stage of the amplifier uses the latest low-noise FET, and the output stage is equipped with an improved emitter follower circuit. The latest design know-how, which follows the trends in driver development in recent years, is condensed into a compact housing. The input and output are equipped with parallel output terminals, so it can be easily combined with your current system. The SRS-X1000 offers a high degree of freedom in placement, making it an all-purpose set model that can be used on a desktop or bedside table, and is recommended not only for listening to music but also for personal movie viewing.
