Hello there, I just purchased a projector (optima hd25 if matters) and I would like to connect my pc/Mac/ps3 to it. So looks like i need a receiver. I'm completely new on this subject and it will be the first time purchasing a receiver for me. I would like something cheap, as this setup will be in my 10x12 bedroom do I won't be needing a power unit. I don't like heavy bass either, suggestions? I would like this receiver to be able to handle 5.1 (although I might only use 2.1 on it but it's good to have options) and 3d function as the projector is 3d capable.
