XLR vs RCA


Can anybody out there tell me the difference between XLR and RCA connectors? Also does anybody have experience with good cables for connecting an Odyssey Temptest preamp to an Odyssey Stratos amp?
Thanks

Please help me about connecting XLR and RCA. My amp and pre-amp have xlr and RCA but my CD player only has RCA. Do you think I should connect pre-amp and amp xlr connectors, and Cd player is RCA connector. Or all connections are RCAs. Do you think there will be a different for connection choice? Please help
i think the biggest difference in a truly balanced design is a dual differential design. the major advantage is less noise since the ground is seperate and you can generally run longer runs of ics.

the positive and negative literally have their own preamp( the output is doubled and the ground is seperate). if a rca connection was balanced, there would be 4 of them.

general rule of thumb, most truly balanced differential designs sound better than single ended...keep in mind, generally.

hope that helps!!
