Could someone explain or refer me to materials that explain what the following "are" and what they "do" compared to each other:
Amplifier Pre-amplifier Surround Sound Processor
I've always assumed buying a top surround sound Receiver (something in the range of $2000) was the best way to produce premiem sound and get enough power for a small home/condo. Now I'm thinking I need to get Amps, Pre-amps, etc.
