SR-404Signature Open-Back Electrostatic Earspeaker |
|
|
| |
|
| |
|
The STAX SR-404 Signature utilizes a new super thin diaphragm of only 1.35 micron in thickness. This unique diaphragm has only been made possible by a revolutionary new material with a molecular structure previously unavailable. The improvement in sound quality and retrieval of inner detail is simply stunning. The STAX SR-404 comes complete with a low capacitance wide format PC-OCC cable for connection to the SRM-006t Driver Unit. |

SRM-006tII Vacuum Tube Driver |
|
|
|
|
| |
| |
In order to make maximum use of the wide-range properties of SACD and DVD audio, the circuit constants have been revised, resulting in a wider than ever replay frequency range. Frequency response raised to 80kHz. (from 44kHz) |
| |
|
| |
| |
Made of rectifier circuits combining low-noise, low-loss Schottky barrier diodes and large electrolytic capacitors. The SN ratio has been improved by means of a low-ripple DC power source.
|
| |
|
| |
| |
A simple two-stage amplifier configuration using a high-resistance dual three-pole tube 6FQ7 (6CG7) results in straightforward properties that make use of the properties of vacuum tubes and a clear sound quality. |

It’s possible to switch between three systems (two RCA input systems and one XLR input system). Pure balance circuit: The electrostatic transducer is driven by electrodes set on both sides of the diaphragm which carry the push-pull signals. This is thus virtually the only replay system that enables the listener to enjoy replay unique to balance transmission without the need to pass through a transformer or an inversion amplifier. The input stage makes use of a rigorously selected low-noise FET. Use is also made of a total of six acoustic high sound quality relays (three on both sides). Simultaneous switching of the hot side and the cold side of the two-system RCA input means that the input source is isolated in terms of direct current, meaning that there is almost no interference between different devices. |
