FIIO M23 stainless steel Limited edition FiiO DAP. Compared to the standard version, it produces a more energetic sound. Purchased as a secondary device on the release date, used it only twice (and never charged it), then stored it away. It's in excellent condition. It was in a case from the time of purchase, and I took it out for the first time to check it this time. There are no scratches, and it's in beautiful condition. Includes all accessories and the original box. Warranty remains for a few months, which I will include after redacting my personal information.
