matching components to speakers

I have a set of Parapigm Monitor 9 speakers, with matched center channel, surround speakers and sub which were bought in Dec/06. I have read that speakers should be matched to components, if so, it can be done the other way around. How do speaker and components get matched? Do Paradigm speakers match well with any particular manufacturer's products. I remember listening to Carver's products years ago and they sounded clear and warm. Has anyone Matched up Carver's Product to Paradigm speakers, and if so what did they sound like. What are Carver's products like today? Are they upper middle of the road, or top end products todaythat would match well with my speakers.
