STAX SRS-3170

STAX SRS-3170

SPECIAL NOTE: Specifications: 220V, Thailand Version, 1 Year Parts & Labor Warranty. NOTE: All units available on Japanese websites are the 100volt for Japan only models. They have no warranty in the Thailand, are a potential fire hazard and will have significantly shortened lives due to the over voltage by Thailand 220V power!!!

The STAX SR-307 and SRM-323S Combo provide a smooth and deep sound with outstanding tonal balance with expanded dynamic range and clear natural sound!

Headphones:
The STAX SR-307 Classic Open Back Headphones feature a New Sound Element, Low-Capacitance Cable, Rich, Deep Low-Frequency and Delicate High-Frequency Sound!

Introducing the STAX SR-307 Signature Open Back Headphones! STAX's first SR-A (Lambda) series Headphones were introducted over 30 years ago, and now the SR-307s have accomplished further evolution with a New Sound Element! The original Sound Element had employed the simplest of structures so that the widest film diaphragm area as possible could be effectively used in comparison with its external size. Taking advantage of the this original feature, the New Sound Element has been packaged in a tough resin case, thus has realized Cleaner Sound and a More Accurate Sound Image. Also a new thin-film material, practically stretch-free through temperature and humidity, has been adopted, enabling both the Rich, Deep Low-Frequency and Delicate High-Frequency Sound.

Features:
• The SR-307 employs a New Sound Element which is encased in a tougher resin to minimize vibration.
• Low-Capacitance cable.

Headphone Amp:
The STAX SRM-323S Headphone Amp has excellent performance for not only musical reproduction but also for monitoring purpose of professional use.

High Quality non-magnetic resistors of audio grade are employed for the main circuit of the new series STAX SRM-323S Headphone Amp, greatly improving the tone quality.

The STAX SRM-323S 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.

SRM-323S Features:
The emitter-follower circuit with high-voltage bipolar transistors adopted for the output stage of teh SRM-323S enabled low output impedance resulting in increased drivability and wide high-frequency dynamic range. Moreover, the power transformer equal to that of the STAX SRM-006tS has been adopted to achieve more powerful drivability. One simple RCA input is equipped with a parallel-out terminal directly providing the incoming signal.

Two 5-pin output sockets are connectable to all pro-bias compatible earspeakers. The SRM-323S employs a double-axis volume controller to control left-and-right channel volume level independently without using a balance volume controller.
