  • The comfortable string and rich mid- and low-range sound of the STAX SRM-006TS Headphone Amp covers all genres from vocal to orchestra and enables you to enjoy music over a long period of time.

    High Quality non-magnetic resistors of audio grade are employed for the main circuit of the new series STAX SRM-006TS Headphone Amp, greatly improving the tone quality.

    The STAX SRM-006TS Headphone Amp also features another Improvement: the circuit constant has been revaluated in detail to improve the sound quality. The signal path is configured with a Class-A All-Stage DC Amplifier Circuit with no coupling capacitors. Carefully selected low-noise hybrid pair-matched dual FET has been employed for the input stage to configure a single-amp balanced output circuit. The result is natural and clear aound regardless of balanced or unbalanced input.

  • High-voltage dual triode 6FQ7/6CG7 Vacuum Tubes are employed in the output stage of the SRM-006TS. The well-sounding righ mid- and low-range tone covers all genres from vocal to orchestra and enables you to enjoy music over a long period of time. The balanced input via XLR terminal along with the custom-made double axis 4-gang volume controller enables a full-balanced operation from input to sound element drive.

    High-quality relays are placed close to the input terminal to realize the shortest signal path, and the mutual interference between equipments is eliminated by switching the hot/cold side of the signal simultaneously. Three lines of inputs are equipped including an XLR terminal. One of the CA input terminals functions as a parallel out directly providing the incoming signal.
