I like to think that I'm not a noob in home theatre, but I really probably am. I feel like I have pretty decent speakers, but I don't know much about the power side of things, so I'm always worried that I don't have the right hardware to suit my speakers. Given my setup below, am I hurting my speakers? Do I need an amp/preamp/better receiver/something else? Setup: Also, since I plan to get a subwoofer at some point in the future, will the answers to the questions above change? Will I need new/different hardware at that point? I really appreciate anyone's feedback! Thanks!
