Query: Great while it worked....

I really, really loved this system. I am no audiophile, but it sounded great to me. It just stopped working shortly after one year. At first, it continued to work but only with the speakers on the base charger. Then it stopped working altogether. If it had lasted, I would have given it five stars. I just don't think it is worth it for one year of functioning.
