Music listening, enjoyable and practical. MUB1’s general sound design is consistent with QA361 and QA390LE. With high sound density and a strong sense of structure, this music is warm, sensitive, steady, and long-lasting to listen to. It has excellent hierarchical details and vertical spatial feeling. The PCB area and power supply of MUB1’s DAC&headphone amplifier section are greater than those of QA361 since it lacks a player part. MUB1 is an inch long and an inch strong, and it has a few advantages over QA361 in terms of sound quality. These advantages include a larger sound field, a more complete sound structure, a sound that is softer and more durable to listen to, greater sound dynamics, and more solid mid- to low-frequency reproduction. 24Bit 96K high-definition Bluetooth Receive mobile streaming input without bundling for convenient and good enough sound Mobile phone connection DAC&Headphone amplifier Pure and abundant local battery power supply. No anxiety of phone battery with excellent sound Office desktop PC-HiFi Desktop small DAC and Headphone amplifier all-in-one machine. Act discrete enough without discrete voice Car HiFi audio source Coaxial / optical input to DSP, or AUX to host. CAR mode with good sound, more convenient Home speaker system Expand high sound quality mobile streaming input function. Simple enough, practical enough, and good sound enough 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 1100mW/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. 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%.
