Hear B&W is even getting into game.Yamaha has had whole system for a while.But as was said A/C is required.I am getting a pair of self amped Quad 11 speakers since none can relive you from A/C.Most of what I have heard from cheaper computer speakers are just OK.Look at recommendations on CNET and if you can go wired if not won't provide same fidelity (Though I wish it weren't so I am running out of RCA and mini plugs everywhere and my A/C strips look like a arsonists wet dream).
