This is the Fosi Audio Phono Box X2 phono preamplifier. Includes the main unit, power adapter, and original box*. *The original box had the shipping label directly attached at the time of purchase, so there are traces of the label and some damage to the corners. Purchased in September 2024 and used until now, but I'm selling it due to a change in equipment. It was used until just recently, and there are no operational issues. There are no noticeable scratches or stains, but please understand that this is a used item and is sold as-is, with no returns or exchanges. Please purchase only if you understand that this is used equipment.
