So I have a brand new macbook pro retina with a hdmi input slot. I am thinking about a surround sound system to just blast some music on for now hook up to my macbook to do this. Currently Im looking at Yamaha YHT-397 5.1-Channel Home Theater System, and was wondering if i could purely just use this system to hook my computer up to it and play some music without being connected to a tv. Any insight on this would be helpful! and the reason I'm looking at the surround sound is that next year I plan on having a house with a tv and then would just convert that to a theater with a tv.
