1971 - 1975
This 1971 classic looks identical to the original Stax SR-3 of 1968, and looks almost the same as Stax' very first SR-1 of 1959.
Comparing the performance of one completely different technology to another, like electrostatic to dynamic transducers, is like comparing the speed of a bicycle to the speed of a car. Even if you've got Lance Armstrong's million dollar brand-new bicycle, my beater 1974 slant-six Plymouth Duster goes a lot faster and farther.
Likewise, this Stax New SR-3 may look old and corny, but its proven electrostatic technology excels at super-low distortion and freedom from any resonance or coloration.
