Logitech Z506 review
Audiophiles are quick to name the umpteen flavors of Dolby, but at the risk of oversimplifying things a tad, there are just three types of surround sound today -- each easily identified by their plug. Virtual surround uses just simple stereo jacks, emulating multiple channels from two, while digital surround travels across optical or coaxial S/PDIF cables (or HDMI) and has to be decoded. Finally, there's analog surround sound -- the cheapest solution of all -- where you basically just plug a pair of dumb speakers into each of front, rear and center 3.5mm sockets on your existing PC sound card. Unsurprisingly, the $100 Logitech Z506 speakers use this last technique to deliver their true 5.1 sound, but that's no reason to count them out. The question is, do they deliver enough bang, boom and tweet for the buck? Read on to find out.
