Query: Disappointing system

Although the JVC VS-DT6 is compact and stylish-looking, the sound quality is less than impressive. There's a curiously high amount of distortion, and worse, my system broke down just two months after I purchased it after very limited use, saying most of my CDs were unreadable. JVC makes some excellent products, but this apparently isn't one of them.
