Cayin’s Magsafe-able tube dac-dongle of 2025 was the culmination of decades of expertise in sound topped by a team involved in making it relevant to today’s listening. Carefully designed with a Gen5 NuTube timbre circuit with refined three-stage amplification architecture, you can choose between three timbres: Classic tube(C), modern tube(M) and solid-state (icon). Try the DC mode toggle to enable the Hyper Mode and hear a deeper rumble in the bass and what additional power can do. The RU9 is also designed with a custom anti-vibration module for the Nutube tube to eliminate microphonic interference and optimise your listening experience. \/\/ SPECIFICATIONS– Tube: KORG Nutube 6P1– DAC: 2x AK4493SEQ– Bluetooth version: 5.1– Supported Codecs: LDAC, aptX HD, aptX LL, aptX, AAC, SBC– Fast Charge: QC3.0 \/ PD2.0– Charging Time: 1.3 hrs– *Battery Life (3.5mm PO\/LO): 4.7 hrs (SS), 3.5 hrs (Tube)– *Battery Life (4.4mm PO\/LO): 4.3 hrs (SS), 3.1 hrs (Tube)*Battery life tested on pure battery mode, source playing 44.1kHz audio, 32 Ohms load, high gain and volume at level 30 \/\/ IN THE BOX– RU-9– Blue leather case– L-shaped USB Type-C to Type-C interconnect– Magnetic adaptor ring (for Android compatibility)– Documentation<\/p>","protected":false},"featured_media":11044,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[28,398,27,410],"product_tag":[178,168,250,179,180,228],"pa_accessories":[],"pa_headphones":[],"pa_connection":[],"pa_fit":[],"pa_type":[],"pa_cases":[],"class_list":["post-10822","product","type-product","status-publish","has-post-thumbnail","product_cat-accessories","product_cat-all-products","product_cat-portable-dac-amp","product_cat-tube-amps","product_tag-accessories","product_tag-audio","product_tag-brand_cayin","product_tag-dac-amps","product_tag-portable-dac-amps","product_tag-tube-amp","entry","has-media","first","instock","shipping-taxable","purchasable","product-type-simple","col","span_1_of_4","owp-content-left","owp-thumbs-layout-horizontal","owp-btn-very-big","owp-tabs-layout-vertical"],"acf":[],"_links":{"self":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product\/10822","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/comments?post=10822"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/media\/11044"}],"wp:attachment":[{"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/media?parent=10822"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product_brand?post=10822"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product_cat?post=10822"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/product_tag?post=10822"},{"taxonomy":"pa_accessories","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_accessories?post=10822"},{"taxonomy":"pa_headphones","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_headphones?post=10822"},{"taxonomy":"pa_connection","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_connection?post=10822"},{"taxonomy":"pa_fit","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_fit?post=10822"},{"taxonomy":"pa_type","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_type?post=10822"},{"taxonomy":"pa_cases","embeddable":true,"href":"https:\/\/theaudiopeople.com.vn\/vi\/wp-json\/wp\/v2\/pa_cases?post=10822"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
