Creative Sound BlasterX G6 (USB DAC/AMP). This is a used item. I was using it as a desktop DAC from my PC, but the headphone jack (front) has broken down. Line Out outputs normally, and it works fine when combined with an external amplifier or active speakers. It uses the CS43131 DAC, and compared to the ibasso macaron, which also uses the same chip, it has a more energetic sound characteristic of gaming devices. It feels like there's more headroom in the sound due to the generous component selection made possible by the size of the enclosure. The exterior has no major scratches. It can be recognized and controlled by Sound Blaster Command. In summary: Headphone Jack: Defective (unusable) Line Out: Works Appearance: No noticeable scratches (some wear and tear appropriate for a used item) Software: Recognized by the Sound Blaster app *I have not used the microphone or optical input/output, nor do I have the environment to test them.* Also, I will include a micro-USB to USB-A cable (the one I actually used to connect to my PC). In other words, the items for sale are the main unit and the cable only. This time, I am selling it as a defective item with partial defects. The current condition takes precedence, and I cannot guarantee detailed operation. Thank you.
