Stax SR-007 MK2 System Combo: SR-007 Omega MK2 Earspeaker with SRM-007tll Driver

This system is comprised of the SR-007 earspeaker and the SRM-007tll driver. Combined, these products give an incredibly magical listening experience! 

The rationale in the development of the new SR-007MK2 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 no holes unlike conventional STAX Earspeakers and thus provides an increases diaphragm vibration area allowing for rich and powerful sound yet retaining all the delicacy STAX is famous for.

The electrostatic system of the SRM-007tll driver entails input by balance, output by balance, and sound conversion by balance, and, in realizing all these features, constitutes the perfect balance system. It is the only system that makes it possible to listen to sound in the ideal manner. The new SRM-007tII is the flagship model of a driver unit intended exclusively for earspeakers characterized by their wide range, high dynamic range and outstanding operating features with full allowance made for SACD and other new-generation high-density formats. The ultra-light polymer film, only a few microns thick, realizes unprecedented response and a high degree of resolution. Since it is driven on all sides, there is almost no partitioned vibration and there is no phase distortion. Nor is there any imbalance in the sound quality of the unit or distortion caused by the network. Electromagnetic distortion also does not occur. It opens up on the world of high sound quality that is the mark of headphone listening, a world characterized by the absence of need for large output, the high degree of freedom permitted by the use of high sound quality elements for use with small signals, and the even balance between left and right unaffected by acoustic conditions in the listening room.
