I also own several of these. They're hidden gems, and their sound quality rivals high-end models costing around 100,000 yen. It's convenient because it supports both MM and MC cartridges. The included power adapter is also a higher capacity than the original, further improving the sound quality. In the unlikely event that there's no sound, I offer a money-back guarantee, so please buy with confidence. Please note that this is not a new item, so please refrain from minor complaints.
