I have a 20" iMac that will be my station for connecting to the Internet and would like to start considering what external speakers would be a good addition. My previous Cambridge Soundworks mini speakers for a 1997 Power Mac, which received kudos from MacWorld during an initial release, served me well. But I am not sure that Soundworks has an equivalent in today's market. I would like as small a space-saving unit as possible yet that still offers rich, sonic capabilities and would visual enhance the desktop where my iMac sits, in preferably a white or silver color. Any suggestions would be appreciated.
