DESCRIPTION
EMBEDDED WITH QUALCOMM CHIP WITH APTX HD SUPPORT
xDuoo MU-603 features the latest QCC3034 Bluetooth chip made by Qualcomm. This chip offers support for Bluetooth 5.1 connectivity which can ensure faster and more stable transmission. It also supports playback for AAC, SBC, aptX and aptX HD protocols for high-quality audio with minimal loss of quality. MU-603 also comes with an external high-gain Bluetooth antenna, which is used to ensure lossless and stable signal transmission.



EQUIPPED WITH A REFERENCE-GRADE DAC CHIP AND A 12AU7 TUBE
xDuoo MU-603 is embedded with the latest ESS ES9018K2M Sabre Reference DAC chip. This high-performance, stereo D/A converter uses the Hyperstream II DAC architecture and Time Domain Jitter Eliminator for performance that ensures high S/N and very low distortion. The audio is further processed by a 12AU7 tube, which pares back some of the shrillness of the upper-end and boosts the mids for an overall warmer βanalogueβ sound.


ACTS AS A PRE-AMP FOR CONNECTING IT WITH SPEAKERS
With a Bluetooth 5.1 receiver chip that lets you control your music from your phone and a 12AU7 tube that gives you that warm tube sound, the xDuoo MU-603 is a DAC/Pre-amplifier that offers the best of both digital and analogue worlds. Connect the MU-603 to your speakers using the AUX outputs for a convenient Bluetooth experience. Control the music from your phone, tablet or other wireless devices. Additionally, the MU-603βs preamplifier function will give your speakers the benefits of tube pre-amplification, with a warmer sound signature.


EXQUISITELY BUILT WITH HIGH-PERFORMANCE COMPONENTS
xDuoo MU-603 adopts the enthusiast Japanese RUBYCON capacitance as the main filter capacitor, to achieve smooth and warm sound. The RCA ports are covered in highly-conductive gold. Unlike silver and copper which corrode in the open air, gold doesnβt oxidise, making it an ideal material for audio connectors. The MU-603βs chassis is crafted by CNC machining, a computerised manufacturing process that achieves incredible precision. Built with aluminium alloy the chassis of the MU-603 resists external electronic interference to keep you hearing your music and nothing but your music.
