Logitech has exceeded our expectations in nearly every department with its Z-680 speaker system.  The clarity in the midrange and highs as well as excellent base response is truly impressive.  We noted excess background noise at low volume — an issue which some will find disturbing and others will not even notice.  In quality the system sounds very similar to its older cousin, the award winning Z-560.  The obvious advantages are the increased power and the move to 5.1 surround from the older 4.1 standard.  Other improvements can be found in the details, but deciding if the Z-680 is worth twice the price of the Z-560 will be a difficult one for most.  If stretching those hard earned dollars is most important, you will likely go for the $100 Z-640 or $200 Z-560.  But if power, sound quality, and features are top on your list, there is not much out there that can contend with the Z-680 sound system.
