What exactly are a Amp and a PreAmp? How, in a nutshell do they add to your overall sound over just having a receiver? Sorry if this is such a basic question it's just that I don't know and I couldn't find distinctive answers. Also, where can I find a good basic introduction on the components of a home theater and what each part does? Thanks in advance for reading this and your responses.

A receiver consists of 3 basic components:

1. A preampflier. It accepts the line level inputs, and controls the volume, and switching between the various inputs, such as DVD, cable box, cd player, etc. In the case of a home theater preamp, also known as a preamp/processor, or prepro for short, it also decodes the dolby digital, DTS, etc surround modes.

2/ An ampflier, it takes the line level input from the preamp and amplifies it to a level that the speakers can use. it typically has no volume controls, usually only an on/off switch.

3. A tuner, to receive AM/FM radio signals.

As you have seen, you can get these components separately from a receiver, which allows you to mix and match the best features with the proper power for your application. The individual components also have the advantage of separate power supplies, instead of a single power supply providing power for all the components, as in the case of a receiver.

I see now all those parts can be found in a receiver. You said that there is a benefit to having the separate parts and that it creates separate power supplies. How is this a benefit? Also if you already have a preamp and a amp is there any need for a receiver? Sorry again if this is too basic but as the title states its a noob question.

The way power ratings are attained is different from a Receiver and an Amplifier. Put simply a reciever rated at 125 wpc will not play NEARLY as loudly or with the same "control" as a seperate amp paired with a preamp. Many believe that if you can seperate out the signals of each of those items they will be able to perform the task they are designed for MUCH better. I agree with this theory.

There is NO reason for a reciever if you have a Pre amp and power amp set up. You may need to add a "tuner" if you want to pick up radio stations, but that would be the only thing missing.

I use Rotel gear and find it to be the best bang for the buck in the seperates category, though many say the Outlaw gear is VERY GOOD! I have not listened to it personally.

As for how much you can spend and what you can get the sky is the limit! There are preamps that cost $20,000 (most of those are 2 channel, so they DON'T EVEN DO Home theater!!), there are amps that are $50,000 EACH and power only ONE speaker! You can probably get a good Outlaw or Rotel set up for 5.1 or maybe 7.1 for about $5k or even less.
