Query: Not really surround sound, but still pretty good

Bought the MAINstage a couple of months ago as a simple solution for better TV sound. The MAINstage helpfully arrives with every type of cable necessary for hooking up your TV and video accessories. Overall, I'd say it does a good job of providing enhanced sound, esp. for dialogue, but it would be an exaggeration to call it "surround sound". Still, for the money and the simplicity, it was a good purchase.
