Stax SRM-252S Driver Unit Class Amplification Amplifier Headphone AMP Used Japan

Stax Srm-252S Driver Unit Class Amplification Amplifier Headphone - Made in Japan - With Power Adapter The SRM-253S was developed based on the STAX SRM-252S as a high sound quality amplifier exclusively for STAX ear speakers. We chose the SRM-252S, the lowest-priced STAX amplifier, as the base because "even in stock (unmodified) condition, the SRM-253S delivers sound quality that exceeds that of high-end models. The SRM-252S uses a pure Class-A discrete transistor DC direct-coupled circuit with no coupling capacitors from input to output, which is only used in high-end audio amplifiers, and its high-frequency reproduction frequency is up to 35kHz (more than sufficient for a headphone amplifier). The high-frequency reproduction frequency is up to 35kHz (more than sufficient for a headphone amplifier), but the low-frequency reproduction limit is possible from DC (0Hz), which is higher than that of the SRM-T8000, and its actual specifications are so superior
