I wonder if a knowledgeable person can help?

I'm quite new on the Hi Fi scene and wondered if anyone can help?

I'm thinking of buying a Power Amp to replace my intergrated amp.

How do i connect the Power amp?

Does the CD, Tuner, etc connect to the Power Amp or do they connect to the PreAmp?

And then the PreAmp connects to the Power Amp?

Please could you advise.

Thankyou
