Stax SR-727 II Omega Reference System

  • Includes SRM-727 II Solid State Energiser and SR-007 Earspeakers
  • Energiser is available in black or silver

The rationale in the development of the new SR-007 Earspeaker was to provide deep powerful sound previously unobtainable in Earspeakers. STAX engineers developed a unique new electrode structure. Visible through the outer case, gold plated on the outer edge this new electrode has less holes than conventional STAX Earspeakers and thus provides an increased diaphragm vibration area allowing for rich and powerful sound yet retaining all the delicacy STAX is famous for.

To maintain clear distortion-free sound it is most important that nothing other than the diaphragm should vibrate. Within the STAX SR-007 the sound element is encased in a thick insulated resin case firmly fixed to the rigid body. The results are nothing short of spectacular.

Utmost comfort for maximum enjoyment of your STAX SR-007 is provided with earpads that are fully adjustable to the shape of your head.
