Hi-fi headphone or earphone STAX Pack SR-307 + SRM-006TS

Headphones: SR-307

These audiophile headphones use electrostatic panel technology and require a compatible amplifier. Thanks to the large emitting 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-307 (gray) and SR-407 (brown) cannot be connected to just any headphone output and require the use of a specific amplifier, particularly due to constraints related to their impedance. These models are compatible with Stax amplifiers.

Note that the SR-407 version is a color variation and has the same characteristics, with the exception of some variations concerning the inductance and impedance of the modulation cable. The listening experience therefore differs somewhat and proves to be even more spatial.

Headphone Preamps: SRM-006TS

The SRM-006ts is a tube amplifier dedicated to Stax electrostatic headphones, from which it knows how to extract the quintessence. It has the particularity of operating in class A with tubes. These are 6FQ7/6CG7 models, whose reputation is well-established among audiophiles. Its warmth and true musicality are present. The input connectivity includes two RCA lines and one XLR. This amplifier can thus be connected to the best audio sources, with SACD players and high-end DACs at the forefront.
