People get messed up in this term "Hi Fi". Hifi actually means high fidelity, that's it, regeneration of sound as close to original as possible.
So, the equipments will be:
1. Source- CD players, LP players (long play), tuners, hard disk streaming, cassettes etc.
2. Pre Amp-this amp controls the power amp with varying voltage different. For your info, power amplifier has only one fixed gain (signal amplification factor).
3. Power Amp- This amp drives the speakers. It amplifies signals, making it very large and could move the speaker diaphragm.
Integrated amp is where the pre and power amps both joined together in a "thing", sharing the main power source. It's more convenient to be used, but it can't give as much power output as the mono blocks (aka power amps). Separated power sources of the pre-power combination gives a better control of the power source, hence eliminated the possibility of left & right channel power being unequally distributed (especially when driving fast paced loud).
Other stuff:
a. Amp can be further divided into tube amp and solid state.
b. Amp can also be divided into class A, A/B & D.
c. CD player can be further divided into 2 compartments: Transport>DAC (digital analogue converter).
d. etc etc....
e. Hardest thing in hi-fi.. Room tune.
That's it!
