Hi-fi headphone or earphone STAX Pack SR-507 + SRM-006TS

Headphones: SR-507

These audiophile headphones use electrostatic panel technology. Thanks to their large emissive surface, the listener is immersed in a musical ambiance that is incomparable to traditional headphone transducers. The main characteristic of the listening experience is absolute transparency across the entire audio spectrum, as well as an absence of lag in the bass. In a word, the listening experience is breathtaking.

The Stax SR-507 differs from the SR-307 and 407 by employing a more ergonomic and finely adjustable headband, as well as using a higher quality cable with oxygen-free silver-plated conductors (99.99999%).

They cannot be connected to just any headphone output and require the use of a specific amplifier, particularly due to the constraints related to their impedance. They are compatible with the brand’s dedicated amplifiers, especially tube models.

For passionate audiophiles.
