I'm starting to replace some of my junk interconnects and was wondering what I should buy for new interconnects.

I'm looking at the following:

New Digital Optical Cable

New Digital Coax Cable

2 Sets of New Analog Cable (CD Player & Television)

Possibly a new Subwoofer cable.

I've been looking at the acoustic research cables at a local audio shop, but this is one area where I have little or no knowledge.

For video I'm using a audioquest silver core component cable.

My Budget is less than $100 for now.
