Are you a music lover and you insist on superior sound quality? If you already own one of the models of first-class electrostatic headphones brand STAX certainly do not forget to take a headphone amplifier STAX SRM-353X. It was sound engineers developed specifically to support quality headphones STAX and brought to your ears flawless and very clean sound. 

Key features

  • for the production of amplifiers have been carefully selected high quality components
  • components are housed in a sturdy three-kilogram body
  • the body is made of non-magnetic aluminum alloy
  • amplifier was developed for cooperation with electrostatic headphones STAX
  • flawless and very clean sound you completely engulfed
  • There biaxial volume control

Superior sound at home

In the manufacture of the transistor were used carefully selected components of high quality. Their purpose is to improve the tonal quality and reach a wider frequency range. The three-kilogram metal body conceals a pair of very quiet low noise FET transistors that can ensure a high input impedance. This will ensure that your headphones mediate naturally tuned and authentic tone output.

Helped by a pair of transistors to achieve high quality sound innovative XLR input offering maximum performance for connected symmetrical signal sources.RCA input impedance at the input is 50 Ohm, XLR input with then full 100 Kohm. Frequency range ranges from 0 to 90000 Hz and has 60 db amplification gain (× 1000). At higher frequencies, you can enjoy a greater dynamic range, which ensures emitter follower output stage. With this equipment at home you can get totally absorbed by the superb sound quality that will simply amaze you.
