The STAX SR-407 and SRM-006tS Combo feature sound quality and retrieval of inner detail that is simply stunning! This results a in clear natural sound, without any unnecessary coloration!

The STAX SR-407 Signature Open Back Headphones feature a New Sound Element, Low-Capacitance Wide Cable, Rich, Deep Low-Frequency and Delicate High-Frequency Sound!

Introducing the STAX SR-407 Signature Open Back Headphones! STAX's first SR-A (Lambda) series Headphones were introducted over 30 years ago, and now the SR-407s 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.

The SR-407 employs a New Sound Element which is encased in a tougher resin to minimize vibration.

Headphone Amp:
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.

SRM-006TS Features:
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.
