Operation confirmed. Fully functional. We have confirmed that all functions are working without any issues. This is a high-resolution audio system that supports 24bit/192KHz and DSD native playback. I am selling it because I rarely use it and have only been storing it. The exterior is a clean used item with no noticeable scratches or stains overall. There are no malfunctions in operation whatsoever. The common issue with this model, where white lines appear on the LCD screen, is also not present. As this is a high-value item, to prevent any problems, please refrain from purchasing if you are overly concerned about minor scratches or fine marks that may not be visible in the photos. The items shown in the first photo are all that will be shipped. It will be shipped after being initialized. Hard Disk Audio Player System HAP-S1 Brand: SONY
