SPECIAL NOTE: Specifications: 120V, U.S. Version, 1 Year Parts & Labor Warranty. NOTE: All units available on Japanese websites are the 100volt for Japan only models. They have no warranty in the USA, are a potential fire hazard and will have significantly shortened lives due to the 20% over voltage by USA 120V power!!!
Class A, Non-Feedback (Non-NFB)
The SRM-727II features non-feedback (NON-NFB) output stage for the first time ever in STAX drivers. Large current emitter follower Class A amplification circuit. This makes it possible to achieve a much more vivid and dynamic sound quality with frequency response raised to 115kHz. (from 100kHz)
A newly designed front panel with rounded corners in brushed finish.
Pure Balanced System
The electrostatic method is a playback method which involves the installation of drive electrodes on either side of a high-polymer film diaphragm with a thickness of only a few microns into each of which a plus signal and a minus signal are fed. This means that XLR connection with a pure balance output CD player makes it possible to listen to the original sound permitted by the balance system without a conversion circuit.
High Quality Parts, High Quality Sound
Careful selection of parts with high consideration on sound quality, performance, and the environment. Low noise FET is used at the input stage with a simple two-stage amplifying circuit. A natural and pure sound quality with high information quantity.
SRM-727II provides a bypass mode that enables "direct" connection to preamplifiers, passive volume controls or integrated amplifiers and receivers with Pre-out. A direct switch that avoids duplication of volume control.
