It combines a sixth-generation KORG Nutube 6P1 tube circuit with a new flagship AKM DAC system of two AK4191EQ modulators and four AK4499EXEQ DACs, and a fully discrete, fully balanced four-channel amplifier giving up to 1,285mW from its 4.4mm output. Three timbres, three amplifier classes and Android 12 with Google Play make it a complete high-end source, made in a limited run of 500 numbered units.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-n8iii-digital-audio-player-photo-hero.jpg?v=1791378147\" alt=\"Cayin N8iii flagship reference digital audio player\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-n8iii-digital-audio-player-photo-tiles.jpg?v=1791378151\" alt=\"Cayin N8iii features at a glance\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSixth-generation Nutube circuit\u003c\/h3\u003e\n\u003cp\u003eTwo KORG Nutube 6P1 dual directly heated triodes are carefully selected and matched by hand.
