Hi, I'm really new to this Home audio field. I just bought the Harman Kardon AVR230 receiver. I've seen alot of people talking about how speakers are more likely to break down from having too little power than having too much. My AVR230 only at most outputs 50 watts x 6 channels. In that sense, does this mean my receiver is more likely to cause problems? I'm planning on getting the RTi8 for fronts, CSi5 for center, FXi3 for surrounds, CSi3 for rear, and maybe the SVS PCi20-39 for sub. What is bi-amping exactly? Will bi-amping help my receiver's output wattage problem? Can I use the Harman Kardon PA2000 amp and AVR230 to power the speakers? Would the PA2000 be a good compliment to the receiver? Please let me know what's the best I should do? Thank you for taking the time and reading this.
