I am looking for a set of speakers with optical digital input. Nearly all seem to be 5.1- to 7.1-channel variety. I have a dedicated home theater for watching movies and listening to surround music. I find multi-channel speakers to be a bit too much for my home office, but I prefer to utilize digital audio connection just the same. Creative's MegaWorks 250D seem to be one such product, but it seems to be discontinued and somewhat unattractive. Anybody know of any products? Or do I have to go with the receiver route?
