will analog interconnects work with a digital source and vise-versa. So if i used digital interconnects with a turntable what will be the outcome? well actually im not really sure i understand the difference between analog and digital. yeah i know what they mean but i guess i don't really understand why you need different cables. oh yeah one more thing is a turntable considered analog or a digital source?

Digital cables have to carry a high frequency in the megahertz since the 0s and 1s change often. You could use a digital cable to carry analog signals and vice versa. The outcome varies.

A turntable is analog. Try various cables out. It doesn't hurt. See if you can hear the differences.

For relatively short lengths (say 2-3 meters), almost any coaxial cables can be used successfully with digital or analog signals.

Don't know if it's true or not but I've heard that TT's is where cables really make a difference.
I'm using mismatched analog cables on my cd player direct to a variable level amp and I don't notice much difference to my ears.

Digital and analog have quite different criteria that make them "good". There are coaxial cables like the Belden 89259 that are good for either use. Also, digital cables have some special requirements like having a 75-ohm characteristic impedance, while the general consensus on analog cables is that the characteristic impedance doesn't matter as much, if at all. Digital cables generally need to be very well shielded, while many analog IC recipes do without a shield altogether (although I still recommend you use one..). Also, the shield has to "protect" different parts of the frequency in analog and digital. With analog you worry most about audible hum, while digital needs to be well shielded up in the Mhz range as lan said.
