iFi audio - GOld bar (18K gold-plated, stick-type USB DAC & amplifier) Limited to 1000 units worldwide Please check the images for the exterior condition, as there may be some scratches. I've marked it as "slightly scratched," but it's actually quite clean. The accessories are as shown in the pictures. Please note that the outer box has significant damage. It still has a little bit of warranty remaining from e-earphone. The previous owner said it didn't work with an iPhone. After some research, it seems to have compatibility issues with iPhones, and cable compatibility can also be a factor. I tested it with an Android device and it worked without any problems, and the sound output was also fine. I thought the sound was rich and had a good reverberation. I like the sound and am happy with it, but I'm selling it because I'm short on money. No returns are accepted to prevent swapping.
