Toroidal transformers have innate advantages: the toroidal core made with non-oriented silicon steel strips provides high efficiency and low eddy current loss, while the corner-free coils result in a more uniform magnetic field and less leakage. Thanks to this power supply, the WARMER R2R is fed clean power that allows it to produce pristine, immaculate sound.\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch2\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eIs a Streamer: ❌ No \u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eFinish; Black or Silver\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003eFrequency Response: 20 Hz -45 kHz \u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\n\u003cspan\u003eDistortion: 0.052%\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eDAC: Fully Differential 24 bit R2R Resistor Ladder DAC\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eLinear Power supply ✅ Yes\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eBit Rate Capability: 32 bit\/768 kHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eBluetooth 5.4 input  ✅ Yes\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eUSB Input ✅ Yes USB-C (2)   384kHz\/32 bit DSD 256\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eDigital input ✅ Yes Coax (1) 192 kHz\/24bit DSD64 Opt (1) 192 kHz\/24bit\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eAnalog out: \u003c\/span\u003e\u003cspan\u003e ✅ Yes RCA (1) XLR (1) \u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003eVariable Audio Out: ✅ Yes\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\n\u003cspan\u003eDimensions;  \u003c\/span\u003e223.5 mm x 213 mm x 66.8 mm\u003cspan\u003e \u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eWeight 6.3 lbs\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eIncluded in the box: \u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0026\/2068\/6447\/files\/fiio_WARMER_R2R_dac_accessories_canada.jpg?v=1779916888\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eSold by Audiofi, we ship free in Canada\u003c\/span\u003e\u003c\/h2\u003e","brand":"audiofi.ca","offers":[{"title":"black","offer_id":47896532484235,"sku":null,"price":599.99,"currency_code":"CAD","in_stock":true},{"title":"silver","offer_id":47896532517003,"sku":null,"price":599.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0026\/2068\/6447\/files\/fiio_WARMER_R2R_dac_black_angle_canada.jpg?v=1779916922","url":"https:\/\/audiofi.ca\/products\/fiio-warmer-r2r-dac","provider":"audiofi.ca","version":"1.0","type":"link"}
