Syntaxerror:Would it make a difference if I were to buy a quality receiver over a amp? Take in consideration that I will be using my speakers for music and movies.
Do you need a tuner, a preamp, decoders for Dolby Digital, DTS, and all the new formats?
An amp, meaning power amp, I assume, includes none of those things. An AV receiver is what you need if you want to watch movies or concert videos in surround sound instead of 2-channel stereo.
Some folks add a power amp to their receiver for more power and better sound quality, often using it to drive only the main speakers, while the receiver's built-in power amp drives the rest of the speakers. However, every power amp needs a preamp, whether it's built into the receiver or is a separate unit.
There's no shame in being an audio newbie, but you might want to read up on what the various components in a sound system do. That way, you'll have a better idea of what you need and it'll be easier to fully grasp any answers you get here.
