The SRM-353X is the exclusive driver unit (amplifier) produced to drive STAX electrostatic Earspeaker headphones.
Carefully hand selected high quality parts of audio grade further improves tonal quality, and achieved wider frequency response from re-examination of circuitry. Newly added XLR input terminal enables connection of balanced outputs of audio equipment taking full advantage of its superior performance.
- Original low noise dual FET at first stage as well as all stage direct coupling Class A DC amplifier configuration with no coupling capacitor has realized natural tone quality with large amount of information.
- Further improved emitter follower at output stage has enabled wide range reproduction resulting in both the extended dynamic range at high frequency and improved over all tonal quality.
- In addition to RCA input terminal, XLR balanced input terminal has been added to provide connection to wide range of audio equipment.
- Custom made 2 axis 4 gang volume control
- Extravagant non-magnetic aluminum alloy chassis
- Components with little aging characteristics are hand selected for tonal quality and performance
Natural Sound & Improved Tonal Quality, Listen Loud
A low noise dual Field-Effect Transistor (FET) is directly coupled with a Class A DC amplifier configuration without a coupling capacitor. This leads to a large amount of information being processed and thus, you are left with audio that sounds natural; as though it were being played right in front of you. STAX has improved upon its previous driver units’ emitters to bring us the current one and in turn, a better output. This reproduces a wide range of frequencies and an overall improved tonal quality. The SRM-353X excels at creating a large sound without any distortion. The custom-made 4 gang volume control with 2-axis ensures that your music sounds crystal-clear even at high volumes.
Always Stay Connected, Beauty at its Best & Music at its Freshest
Now, you don’t have to worry whether you can connect your audio device with the STAX SRM-353X. This driver unit comes with both—an RCA input terminal as well as an XLR balanced input terminal. Apart from sound, the SRM-353X also excels in its looks. The non-magnetic aluminium alloy chassis gives it an elegant look. The silver finish adds an extra shine to this driver unit. Each component is handpicked so that you only get the best. Each element is inspected so that there is no ageing and your music sounds as fresh as it was on day 1.
