Gungnir
Lotoo’s new reference-quality desktop DAC/amplifier with LTTP Lossless Audio
Reviews
"Lotoo’s Gungnir DAC/Amp is yet another fantastic device featuring their dynamic and neutral sound signature. It offers an abundance of power to drive even the most demanding headphones. But also gives us the flexibility to use super sensitive IEMs with it.
The Gungnir is a rock-solid choice for anyone who’s looking for a compact, versatile and powerful one-box solution. To me, it is the best one in that category and deserves its newly earned spot on Headfonia’s best desktop DAC/Amp list."
Lotoo Gungnir Review - Headfonia
"Throughout my testing, Gungnir repeatedly matched Mjolnir’s refinement and control, and in several areas – especially depth, neutrality and outright amplifier headroom – it went even further. At less than half the price price, it therefore represents considerable value for high-end audio enthusiasts who may not need Mjolnir’s standalone bells-and-whistles but still want its core functionality.
As such, Gungnir is one of the most convincing premium DAC/amps I’ve personally come across, and earns my highest possible recommendation for both desktop and portable audio users alike."
Review: Lotoo Gungnir | The Headphone List
Gungnir was developed for those who demand uncompromising audio fidelity in a compact form, delivering powerful performance and precise signal control in a fully integrated desktop solution.
Whether you’re driving high-impedance headphones, powering a reference speaker system, or streaming lossless audio via LTTP wireless technology, Gungnir adapts effortlessly and is designed to serve as the centerpiece of your desktop audio 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.

160W High-Power USB PD Power (optional power supply)
Lotoo's latest innovation, the 160 W High-Power USB PD power supply, is a powerful power solution carefully engineered to deliver clean, stable, and robust energy to even the most demanding audio systems.
With a peak output of 160 W, 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 when powering multiple devices helps minimize dynamic compression caused by insufficient power and ensures consistent performance for all connected devices.
Designed as a Hi-Fi-grade USB power source, it embodies Lotoo's extensive expertise in precision power delivery and its tireless pursuit of uncompromising sonic purity.
Beyond its exceptional performance, this model also serves as an Extended Power Hub, offering versatile connectivity for multiple devices through 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 multistage power-cleaning system is a hallmark of Lotoo's power-supply engineering. It features four-stage filtering from input to output that effectively eliminates 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.
Ultrafast transient response for absolute stability
- When transitioning from 5% to 100% full load, voltage recovery is completed within 5 µs, with a deviation of just 30 mV, guaranteeing stability even during the most demanding musical passages.
- With an output impedance of just 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 voltage regulation accuracy of 1/1000.
Comprehensive protection and shielding
- Complete electromagnetic shielding: The robust metal housing provides complete isolation from external interference.
- Multilayer safety protection: Integrated safeguards against overvoltage, overcurrent, short circuits, and overheating ensure uninterrupted reliability and absolute safety.
Flawless power for pure sound
