I have seen a review, its a cheap device and not comparable to the masterpieces of Sony, Aiwa and other brands back then. Your used deck probably needs servicing like belt or idler rollers. Everything is fixable in such old devices, the Fiio-stuff can only be thrown away because of lack of parts and service manuals. Get an old Walkman, there are many revised ones for sale, in every price range. They will sound better and will run some more years as the cheap china crap.
