The Stax SRS-4040 MK2 Signature System comprises the SR-404 Earspeakers and SRM-006t MK2 tube driver unit.
The Stax SR-404 Signature utilizes a new super thin diaphragm of only 1.35 micron in thickness. This unique diaphragm has only been made possible by a revolutionary new material with a molecular structure previously unavailable. The improvement in sound quality and retrieval of inner detail is simply stunning. The Stax SR-404 comes complete with a low capacitance wide format PC-OCC cable for connection to the SRM-006t driver unit.
SRM-006t MK2 (Driver Unit):
The SRM-006tII driver unit shows the true value of electrostatic Earspeakers. Pure balance, DC amplifier configuration. The key concept is the output stage employing a high sound quality vacuum tube 6FQ7 (6CG7), and further refinements have been introduced into all the individual parts for a wider frequency range than ever before.
