Pure R2R DAC Architecture:
QULOOS MUB5 features a 19+5 segmented R2R DAC arrangement. It features 178 precision-matched resistors, which are matched with 0.01% tolerance. This R2R DAC arrangement provides crisp, high-resolution audio signal processing and delivers a rich, musical sound profile with high accuracy and pure high-resolution audio excellence.

Customize Your Sound With Two Filter Options:
QULOOS MUB5 has two filter options, custom Oversampling(OS) and No-Oversampling(NOS/M1). The NOS mode packs an accurate, expansive, and precise sound response, while the NOS mode delivers a relaxed sound response. The NOS mode provides pure sound as it is recorded and shows no coloration from the MUB5.

Fully Discrete High-Power Amplification:
QULOOS MUB5 features a fully discrete headphone amplification section with FZT power transistors and OPA627 chips in the buffer stage. It produces an impressive output thrust reaching up to 1.5W in battery mode and up to 2.5W per channel in 12V DC-in mode. With such a strong output, MUB5 drives most IEMs and Headphones with ease. Even for demanding Headphones, MUB5 works like a charm.

Multiple Input, Output Options:
QULOOS MUB5 is a high-end portable DAC/AMP. It has multiple input and output options, which make the MUB5 a highly versatile device that fits into every scenario. It supports USB, Coaxial, Optical, and Bluetooth connections for input. With 3.5mm and 4.4mm headphone outputs and line-out functionality, the MUB5 can work as a headphone amplifier as well as an adjustable preamp.

Clean Power Delivery with Properly Shielded Power Supply Design:
QULOOS MUB5 gets clean power to each component on the circuitry. The DAC/AMP features specially designed NDCS shielded power supply with 20 independent power circuits, LTC6655 voltage reference chip, and QA661 crystal oscillators. With such a clean and efficient power supply design, the MUB5 offers ultra-clean performance with no noticeable interference from the power supply. It has a rated battery life of about 7 to 8 hours and supports QC fast charging protocol as well.
