The two new driver amplifiers SRM-700T and SRM-700S benefit from the technologies used in the flagship SRM-T8000: In the new tube driver amplifier SRM-700T, which does not require output transformers (OTL), STAX uses two 6SN7 double triodes and non-inductive winding resistors from Vishay Co., as well as specially manufactured low-noise dual-FETs in the first amplifier stage, which are also used in the transistor sibling STAX SRM-700S. There, STAX has for the first time ever implemented J-FETs in the second amplifier stage of a STAX driver amplifier. J-FETs are suitable for particularly low-noise amplification of even the most power-hungry transducers.\n\u003cbr\u003e\n\u003cbr\u003eIn this way, STAX catapults the performance of both models far beyond their price range. STAX has also modernized the amplifiers visually, giving them an extremely elegant new look.\n\u003cbr\u003e\n\u003cbr\u003eSTAX SRM-700S, the sonic alternative to the STAX SRM-700T at the same level of quality. Compared to the SRM-700T, it is slightly less colorful and resolving, but more controlled and tighter in the bass. Symmetrical circuit design. Volume\/balance control via a quadruple potentiometer encapsulated for electrical shielding.\n\u003cbr\u003e\n\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cb\u003eSimultaneous operation of two STAX headphones is possible with the STAX SRM-700S.\n\u003cbr\u003e\u003c\/b\u003e\u003c\/span\u003e\u003cspan\u003eSTAX electrostatic headphone driver amplifiers can be operated from the record output (tape\/record out) of preamplifiers and integrated amplifiers or from the preamplifier output (pre out) of a preamplifier. The source device to be played is then selected using the input selection of the preamplifier or integrated amplifier. The integrated volume control can be switched off if the volume is to be controlled via the preamplifier or integrated amplifier.\n\u003cbr\u003e\n\u003cbr\u003eHowever, a CD player or a turntable with a separate phono preamplifier can also serve directly as a signal source. The music signal present at the input of the driver amplifier can be looped through to connect another device. If a source device is to be connected digitally, a separate D\/A converter is necessary. Connection can be unbalanced or balanced.\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cb\u003eNote on the operating voltage (polarization voltage) of STAX headphones\n\u003cbr\u003e\u003c\/b\u003e\u003c\/span\u003e\u003cspan\u003eMany early STAX headphones are designed for an operating voltage of 230V\/DC. PRO-series headphones - which include all current models - require a higher operating voltage of 580V\/DC.\n\u003cbr\u003eIn the past, driver amplifiers were offered that also provided both operating voltages. Current devices only have connections for the higher operating voltage of 580V\/DC.\n\u003cbr\u003eTo avoid confusion, the connection sockets for the different operating voltages have different pin assignments.\n\u003c\/span\u003e\u003c\/p\u003e","brand":"Stax","offers":[{"title":"Black","offer_id":52457212313866,"sku":"141257","price":3950.0,"currency_code":"EUR","in_stock":true},{"title":"Silver","offer_id":52457212346634,"sku":"141256","price":3950.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/5340\/0586\/files\/img141257_89015.jpg?v=1769454258","url":"https:\/\/hifi.shop\/en\/products\/stax-srm-700s","provider":"Hifi \u0026 Friends GmbH","version":"1.0","type":"link"}
