basic idea of R-2R ladder is a matched pair of two resistors, the first is \"R\" and the other is \"2R\" which has twice the value of R.\u003cbr\u003e\u003cbr\u003eTo achieve 24bit R-2R decoding, Cayin need 48 pieces of resistors (23xR and 25x2R) for one channel, or 96 pieces of high precision resistors for stereo.\u003cbr\u003e\u003cbr\u003eR-2R is famous for its natural and realistic sound signature, it'll offer a very different experience to music lovers.\u003cbr\u003e\u003cbr\u003eTo achieve 24-bit R-2R decoding, Cayin searches for the resistors that can deliver extreme precision and remain stable during temperature changes.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eUltra Precision Low TCR Thin Film
