Review:
I really like to have balanced outputs in a DAC given the fact that they connect to a PC and hence, it is very easy to wind up with ground loops. Usually balanced output comes at a cost of higher price as it is considered a premium feature. Not the case here. You get XLR output and importantly, with superbly low noise and distortion for a really budget price. The nice case completes the picture.Given all of this, I am happy to recommend the Soncoz LA-QXD1 DAC." Amir Majidimehr (Amirm), Audio Science Review Read the full review here

Miscellaneous
The LA-QXD1 is a multifunctional DAC, in addition to the features and settings mentioned earlier, there are some precautions:
-
Analog balanced XLR and single-ended RCA outputs can be connected at the same time，The The two interfaces can be simultaneously connected to their corresponding power amplifier devices (amplifier/power amplifier).
-
LA-QXD1 is a high-performance DAC that can also be used as an excellent Pre-amp.
-
The DAC’s internal modulator, filters, and volume control cannot be bypassed. These functions are determined by the DAC chip.
-
LA-QXD1 can be easily used in pure DAC mode，to do so, simply raise the volume to the maximum.
-
The Volume adjustment and mute functions are only valid for the analog outputs. They are not valid for digital output.
-
During DSD playback, the DSD audio signal is sent directly to the DSD decoding chip without any prior conversion.
-
Custom USB driver，supports up PCM768KHz/DSD512（Native），Drivers are not required for the device's functionality. If you use the operating system's native USB Audio 2.0 Drivers (UAC2), Some formats and high sample rates may not be available for playback.
-
Do not use the USB ports of the PC to supply power to the DAC. The USB port of the PC has an average current of around 500mA, which is not enough to support the normal functions of the LA-QXD1.
Thermal design
-
The power consumption of the LA-QXD1 device is very low. The low energy consumption combined with the CNC machined aluminum body results in a high heat dissipation efficiency.
-
Keeping in mind that if used in conjunction with other devices, the overall heat dissipation may not necessarily be the best. Multiple ventilation holes were implemented on the underside of the LA-QXD1, to provide excellent cooling and ensures thermal stability. This thermal design guarantees the highest performance levels under a variety of harsh environmental conditions.
Ultra-Low Noise HiFi Power Supply System
The LA-QXD1 power supply system utilizes a unique multi-level voltage regulator design to ensure a clean & pure power supply that guarantees the performance of the entire device.
-
Power input uses USB Type-C 5V@1A，Practical and convenient
-
The Analog op-amp power supply utilizes multi-level voltage regulation.
-
The power for the DAC’s digital section is supplied by an ultra-low noise LDO.
-
The DAC's analog power supply uses ES9311Q ultra-low noise LDO and multi-level voltage regulator.
High-Performance Chips
LA-QXD1 utilizes individually selected chips that each offer excellent performance to ensure the outstanding performance of the entire device.
Minimal Interaction, Warm Color Indicators
-
The intuitive interaction of the LA-QXD1 is applied to simple and straightforward buttons and LEDs. By default, it is a plug-and-play device without any complicated settings.
-
The indicator lights follow the color pattern of the indicator lights of the SONCOZ brand series of products. The warm, non-glaring, glowing orange light perfectly blends into the ambiance and relaxing atmosphere of enjoying music at night.
