This successor to the SRM-006tS incorporates custom low-noise dual FET input stages and high-voltage 6FQ7\/6CG7 output tubes, maintaining STAX's signature circuit philosophy while delivering measurable improvements. The dual-winding power transformer enhances supply efficiency and reduces power consumption without compromising sonic performance. A newly engineered chassis with non-magnetic aluminum construction increases rigidity and minimizes vibration-induced artifacts. The complete DC amplifier topology—featuring no coupling capacitors in the signal path—preserves the transparent, detailed midrange clarity characteristic of tube designs while adding enhanced low-mid density and warmth. Dual RCA and XLR inputs with parallel RCA outputs provide flexible integration into professional and audiophile systems. Meticulously selected components throughout ensure long-term reliability and refined sound quality.\u003c\/h4\u003e\n\u003cdiv title=\"Page 1\" class=\"page\"\u003e\n\u003cdiv class=\"layoutArea\"\u003e\n\u003cdiv class=\"column\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Stax","offers":[{"title":"Default Title","offer_id":47545164824628,"sku":null,"price":1499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/7030\/5588\/files\/SRM500T_1024x1024_2x_395a239d-c7e0-42a4-9e4b-35f00b57478f.webp?v=1772566713","url":"https:\/\/www.theheadphoneshop.com\/products\/stax-srm-500t-vacuum-tube-driver-unit-for-earspeakers","provider":"The Headphone Shop","version":"1.0","type":"link"}
