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  test by the Audio Science Review measurement forum

 The LA-QXD1 is a multifunctional DAC, in addition to the features and settings mentioned earlier, there are some precautions:

  1. 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).

  2. LA-QXD1 is a high-performance DAC that can also be used as an excellent Pre-amp.

  3. The DAC’s internal modulator, filters, and volume control cannot be bypassed. These functions are determined by the DAC chip.

  4. LA-QXD1 can be easily used in pure DAC mode,to do so, simply raise the volume to the maximum.

  5. The Volume adjustment and mute functions are only valid for the analog outputs. They are not valid for digital output.

  6. During DSD playback, the DSD audio signal is sent directly to the DSD decoding chip without any prior conversion.

  7. 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.

  8. 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 

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.

  • Does the LA-QXD1 remember the volume if it is powered on/off?

    LA-QXD1 can't remember volume if it is powered off.    

  • When powering on the DAC, it will default to the USB input, and you then have to press the input selector to use the coaxial input?

    Yes, correct.  

  • Will it remember this volume setting if it is powered off and back on? (If not it is not DAC mode)

    LA-QXD1 can't remember volume if it is powered off.

  • Can I output sound to two different amplifiers at the same time?

    This risk is not recommended.  

  • Is it possible to disable volume control and have pure direct DAC use with LA-QXD1?

    Turning up the volume to the maximum is a pure DAC application.  

  • Just to make sure I understand correctly, does this mean that when the LA-QXD1 is switched on, it will default to the USB input, and you then have to press the input selector to use the coaxial/SPDIF input?

    Yes, correct.  

  • On the previous model, if there was no input on USB and there is input on SPDIF, then the SPDIF signal is used. Would the same happen on the QXD1?

    Unfortunately, no, you need to switch to the coaxial input manually.    

  • What happens if nothing is connected to USB, and there\'s a signal on the SPDIF input - does the LA-QXD1 automatically switch to SPDIF?

    No, you have to switch the input source selection manually.    

  • If I have SPDIF Coax selected as an input, switch the DAC off, will it go back to SPDIF Coax when switched back on?

    The LA-QXD1 doesn't remember the input settings when powered off/on.  

  • Does the unit remember the source input setting when switched off/on?

    The LA-QXD1 doesn't remember.  

  • Will it be possible to play music from a MacBook or an iPhone?

    Yes, it will switch on.

  • Does just one USB 2.0 port power the unit or require an external power bank?

    It requires an external power bank or adapter via USB TYPE C and USB-B just for USB audio.  

  • Is there a sound quality difference between the LA-QXD1 and the SGD1?

    It will be different. Different power supply and DAC architectures and different capacitance choices will bring different sound quality!But the difference is not unusually large.  

  • Does the LA-QXD1 DAC or SGD1 turn off automatically if nothing is playing for a while?

    SGD1 goes into standby mode after about 10 minutes on mute (when you're not listening to music to take a break or answer an urgent phone call). LA-QXD1 has no standby function for the moment, and we will consider upgrading the software to implement it later.    

  • Can I connect my LA-QXD1 DAC using a JTAG connector and modify its firmware?

    For adapters, LA-QXD1 has no special requirements(Multiple adapters have been tested, If you want to feel better, you can use power bank ), as long as it can steadily output more than 5V2A power adapter. A regular phone adapter is the right choice, and It is not recommended to use the USB interface of the computer, mainly because the power may not be enough(5V@500mA). The internal amplifier circuit of LA-QXD1 has a positive and negative voltage booster circuit, and the external start power supply should ensure 5V1A. Otherwise, the circuit may be unstable. BTW, the power consumption of LA-QXD1 in regular operation is about 3.8W.
