Gungnir
Lotoo’s new desktop DAC/amplifier in reference quality with LTTP lossless audio
Gungnir was designed for those who demand uncompromising sound fidelity in a compact form, offering powerful performance and precise signal control in a fully integrated desktop solution.
Whether you operate high-impedance headphones, drive a reference speaker system, or stream lossless audio via LTTP wireless technology – Gungnir adapts effortlessly and is conceived as the heart of your desktop sound system.
The name Gungnir is inspired by Norse mythology – the legendary spear of Odin, known for its precision, power, and flawless accuracy. We chose this name to reflect Gungnir’s ability to deliver pinpoint signal control and reference-level performance with unwavering reliability.
The sound is so impressive and effortless that you may find yourself listening for hours on end.

Design Concept
A high-end audio system united in a compact desktop form. True to Lotoo’s core philosophy, Gungnir combines the performance of full-size high-end systems in a compact and adaptable form factor.
It is small enough to fit on a personal desktop, powerful enough to drive a complete audio setup, and flexible enough to be used portably when needed.
With rich connectivity, a compact form, and uncompromising performance in a unified design, Gungnir is designed to meet the highest expectations for high-end audio – whether for desktop hi-fi, precisely crafted wireless setups, or full system integration.
It is an indispensable audio device designed for the many ways we enjoy music today.
160W High-Power USB PD Power Supply (optional power adapter)
Lotoo’s latest innovation, the 160W high-power USB PD power supply, is a powerful power solution carefully designed to deliver clean, stable, and robust energy even to the most demanding audio systems.
With a peak output of 160W, it not only provides ample power for Lotoo’s professional audio devices such as Mjölnir and Gungnir but also powers digital source components – including USB DACs, headphone amplifiers, smartphones, and hard drives.
Its exceptional stability in multi-device operation helps minimize dynamic compression caused by power shortages and ensures consistent performance for all connected devices.
Designed as a hi-fi capable USB power source, it embodies Lotoo’s long-standing expertise in precise power supply and its tireless pursuit of uncompromising sound purity.
Beyond its exceptional performance, this model also serves as an extended power hub, offering versatile connectivity for multiple devices via two Type-C and one Type-A output.
Power Meets Versatility
Equipped with two Type-C and one Type-A interface, the USB PD power supply fully complies with the USB PD 3.1 standard and supports output voltages of 5 V, 9 V, 12 V, 15 V, and 20 V at a maximum current of- The multi-stage power purification system is a hallmark of Lotoo’s power supply technology. It features four-stage filtering from input to output, effectively eliminating high-frequency switching noise, RFI, and EMI.
- Frequency shift reconstruction moves in-band noise to higher frequencies, significantly reducing audible interference and maintaining a crystal-clear signal environment.
Ultra-fast transient response for absolute stability
- During a transition from 5% to 100% full load, voltage recovery is completed within 5 µs, with a deviation of only 30 mV, guaranteeing stability even in the most demanding musical passages.
- With an output impedance of only 30 mΩ, it delivers exceptional current drive and preserves dynamic headroom under any load.
- When the load changes from 0.5 A to 3 A, the output voltage fluctuation is limited to 0.1%, demonstrating a voltage tracking accuracy of 1/1000.
Comprehensive protection and shielding
- Complete electromagnetic shielding: The robust metal housing provides full isolation from external interference.
- Multi-layer safety protection: Integrated safeguards against overvoltage, overcurrent, short circuit, and overheating ensure uninterrupted reliability and absolute safety.
Flawless performance for pure sound
