If anyone's after a "budget" option I have Edifier S550 speaker set that I've been meaning to sell - used to 2 years then sat in its box for another year or so, as good as new other than some dust. Amazing sound for the price. It's made for a computer but could work with a home theater system, though it has 5 stereo plugs not HDMI input. It has sub, front left, front right, back left, back right, and center speakers, the sub is the amplifier for them all. Comes with a remote. Cost around $700, open to offers via PM.
