    Packs a punch
    I bought this recently to provide a music system in the garden using my iPod or iPhone as a source. It works really well. All types of music, from rock to vocal to classical are reproduced clearly and with great detail. The only reason for down-rating it to 4 stars is that in my opinion it has to be driven hard to work well, so using it for ambient music as a background isn't its forte.
