I purchased this item from this site. I have no complaints about the sound or operability, but I am selling it because I have too many. I also own an SP3000 Platinum, but I feel that the SP2000 is better made. However, there is one issue, so please read this carefully: The 3.5mm jack, 2.5mm jack, SD card slot, buttons, and volume knob have been confirmed to be working. I am significantly lowering the price compared to the market value because it often freezes when playing DSD files and the SPDIF optical output does not work. The accessories are missing one of the two SD slot covers, but otherwise, they are all included. Screen film, back glass film, and top film are each applied. There are some minor scratches and oxidation on the main unit, but there are no major noticeable scratches or dents, and I think it is generally clean. The white part on the top is air bubbles in the film.
