Small But Extraordinary

QULOOS MUB1 weighs as much as an iPhone 6s, only about 142g. You can use it in many places, and it has more usage than the usual DAC/AMP. You can use it as a 24-bit 96k HD Bluetooth player for streaming, which is easy to use and convenient while having good sound quality. MUB1 has a battery capacity of 2500 mAh. When you link your phone through the cable, QULOOS MUB1 can charge your phone while providing high-quality music. When you connect it to your laptop, it can be a decoder-amplifier all-in-one. In-car mode connects the audio source and car with Bluetooth / coaxial to play high-quality sound. The same approach can be applied to home audio systems.

Super Power, Super Gain

The balanced port output power of MUB1 is up to 100mW/ch, which is 2.75 times higher than that of the QA361 double-high mode. Meanwhile, its S gain is 3 to 4 times the voltage amplification of the high gain. In fact, MUB1 uses Panasonic Electrolytic Capacitors (material used for desktop HiFi) and BUF634 (material used for desktop AMP), and Wurth Alloy Inductor. With these designs of QULOOS, the jitter range of MUB1 is around 150fs.

Products are Designed for Performance

MUB1 has a powerful 14-way independent power supply system. On top of that, it has four levels of Super-high gain as well as a four-stage independent HiFi structure (Digital/DAC/OP/BUF). Among them, PCM(Pulse Code Modulation) supports up to 32bit/384kHz, and the highest specification of DSD(Direct Stream Digital) hardware resolution supports 256.

4 Cirrus Logic flagship DAC Chips

QULOOS has loaded MUB1 with four new generation CS43198 chips from Cirrus Logic. The CS43198's unique Nos mode makes the sound more realistic and accurate. At the same time, the eight-channel DAC is designed into two channels, each channel is responsible for four channels of DAC, which allows the sound to have more details. SNR up to 132dB, THD+N as low as 0.0001%.

Great sound, fully satisfied

Liked it more than anything else I tried before (BTR5, Shanling UP5, BTR7, xDuoo XP-2 Pro). Great sound, good battery, UI is nice too.

John Nelson
Very nice quality DAC

This new DAC has variable levels of sound decoding with good sound detail. The Quloos MUB1 DAC is small and has not only high quality analog but Bluetooth as well. An internal rechargeable battery and gain control makes for a great portable DAC which I love. Highly recommend the purchase.
