This configuration delivers straightforward, authoritative performance with refined sonic characteristics. High-grade non-inductive VISHAY resistors serve as load elements, enabling rapid transient response and extended dynamic range. The result is a transparent, tube-driven presentation marked by warmth and spatial depth, elevating the listening experience with enhanced clarity and musicality.\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003e●Type: FET input + vacuum tube output hybrid DC amplification driver unit  ●Vacuum tube: 6SN7\u003cbr\u003e●Frequency response: DC - 100kHz (with one SR-009S)\u003cbr\u003e●Gain: 60dB\u003cbr\u003e●Harmonic distortion: 0.01% or less (1kHz\/100Vrms output)\u003cbr\u003e●Input impedance: 50kΩ (RCA), 50kΩx 2 (XLR)\u003cbr\u003e●Maximum output voltage: 340Vrms (1kHz)\u003cbr\u003e●Bias voltage: PRO 580V\u003cbr\u003e●Operating temperature \/ humidity: 0 to 35 degrees C \/ less than 90% (non condensing)\u003cbr\u003e●Input terminal: RCA x 1, XLR x 1\u003cbr\u003e●Output: RCA parallel output terminal\u003cbr\u003e●Power consumption: 54W\u003cbr\u003e●Dimension: 240W x 103H x 393D mm (maximum protruding portion included)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e ●Weight: 5.7kg\u003c\/span\u003e\u003c\/p\u003e","brand":"Suncoast Audio Direct","offers":[{"title":"Default Title","offer_id":47636058177774,"sku":null,"price":3400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/6683\/0574\/files\/SRM-700T_1024x1024_2x_d70384df-7bb2-416c-b676-fb60a37542ca.webp?v=1770242026","url":"https:\/\/www.suncoastaudiodirect.com\/products\/stax-srm-700t-vacuum-tube-driver-unit","provider":"Suncoast Audio Direct","version":"1.0","type":"link"}
