I've been looking for a set of high quality pc speakers. Notably, I want to try and get the best of the best, for a multimedia pc audio system. It's been boiled down to the Logtitech Z-5500 system, or the Klipsch ProMedia Ultra 5.1. I've searched the form and read the threads, what I want here is to try to just blatantly see which is preferred, and what equipment is needed for each. Which one is the Best, basically. I know that for the Logitech I will need an optical audio cable, the only problem is I'm not sure what exactly I'm looking for in that. Help would be appreciated. For the Klipsch, I hear I'll need an external sound decoder, but again I have no idea about what I'm looking for in that, or where for that matter, as I've yet to find one at all. Help, again, would be appreciated. Finally, what are your opinions on these speakers? Comparative opinions would be even better. And if you know of a better set, please by all means inform me. What is the Best? Thanks for all your help, and cheers to all.
