xDuoo MU-603 Bluetooth DAC/Tube Preamplifier
Warm and wireless
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/Preamplifier that offers the best of both digital and analog worlds.
Get high-def sound quality with Qualcomm’s QCC3034 Bluetooth 5.1 chip. With fast and stable connections, it supports audio codecs like AAC, SBC, aptX, and aptX HD.
The sound is processed by a 12AU7 tube, which pares back some of the shrillness of the upper-end and boosts the mids for an overall warmer “analog” sound.
Go wireless with your bookshelf speakers
Connect the MU-603 to your bookshelf or floor speakers for a convenient Bluetooth experience. Control the music from your phone, tablet, or other wireless device. Additionally, the MU-603’s preamplifier function will give your speakers the benefits of tube preamplification, like a warmer sound signature.
Reference-grade DAC chip
Rediscover your library with the 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 will satisfy even the most demanding of audiophiles.
Gold-plated RCA ports
The RCA ports are plated in highly-conductive gold. Unlike silver and copper, which corrode in the open air, gold doesn’t oxidize, making it an ideal material for audio connectors.
Aluminum alloy chassis
The MU-603’s chassis is created by CNC machining, a computerized manufacturing process that achieves incredible precision. Made of aluminum alloy, the chassis resists external electronic interference to keep you hearing your music and nothing but your music.
