STAX SRM-700T
The newly designed SRM-700T is a hybrid electrostatic headphone driver. Inspired by the flagship model SRM-T8000, the 700T uses solid-state FET as a driver stage and vacuum tube as the output stage.
The first stage is a custom-made low-noise dual FET while the second stage is clear and high slew-rate vacuum tube 6SN7. The tube output offers warm and spacious music reproduction.
Hand selected matching FET
High-definition film capacitors are used
Bypass volume control switch
Volume control is EMI shielded
Switchable RCA and XLR inputs. RCA parallel out.
The newly developed large-sized aluminum insulator combined with new vibration-proof material and high frictional coefficient (grip power) have been employed.

STAX SR-009S (new flagship)
Multilayer fixed electrode MLER (Multi-Layer-Elect-Rords) established with SR-009 has evolved to MLER 2. The finish and etching process that smoothes the edge of the electrode opening reduces air resistance and further improves sound permeability. Also, the electrodes themselves are gold plated with high specific gravity to minimize the resonance of the ultra-thin electrode. At the same time, due to the effect of reducing the electric resistance of the electrode itself by gold plating, we have opened up a new ground for high speed, clarity, silky details, and powerful texture.
SR-009S adopts a diaphragm made of ultra-thin super engineering plastic film. The light mass has realized a high transient characteristic throughout the entire audio spectrum.
The main body was redesigned to further reduce resonance as to provide a consistent sound.
ENCLOSURE:
Aluminum is a metal good for sound and suitable material for audio equipment. It is abundantly used, e.g. at the frame supporting the appearance and sound element, to realize high-quality sound, rigidity and lightweight. Almost every part of the SR-009 is manufactured through precise machine processing.
CABLE:
The high-purity copper developed from the necessity of wiring large-scale integration circuits is also known as high-quality audio cables. High-purity copper wire of 99.9999% (6Nines) purity adopted for the cable is further silver-coated and finished with the most suitable structure to drive the earspeaker.
EARPAD:
The earpad of a new design is carefully made by a craftsman's hand and features both the real leather with good humidity environment and the cushion material with moderate elasticity.
The new earpad enables hours of comfortable listening to music.
ARC (head band):
The arc is equipped with a position adjustment mechanism of 10-step slider and corresponds to the wide range of cranial form with individual difference.
