RCA vs XLR and Balanced vs Unbalanced

Newbee needs some help understanding the benefits (if any) of using RCA vs XLR connections and using a balanced vs unbalanced components. What are the benefits of using balanced components (DAC > pre-amp >  amp)?   Does balanced sound better for some reason?    It is my understanding that to take advantage of a balanced system, you need to use XLR cables. Correct?  RCA cables will negate the benefits of a balanced system?  For example, if I have a set of cables that are terminated with XLRs on the DAC end and RCAs on the pre-amp end.  If I have a balanced DAC should I be using a balanced pre-amp? A balanced amp? As my line of questioning indicates, I have no understanding of how a balanced system works and why it is preferable to a non-balanced system. Any guidance will be greatly appreciated. Cheers.

If you a long run and potential noise problem XLRs really help. If you don't have EMI RFI noise issues, RCAs and the length of the run work just fine. One thing is for sure XLRs have a better secure connection.
The exception is locking RCAs.

Most XLRs are louder too. 3 or 6 db something like that.

BTW not all balanced systems are created equal.. They can have XLR plugs and cable but not be balanced.. There are a FEW tube amps that way..

Someone will chime in with all the tech stuff. 

Noise is the issue and are you happy with what you already have?
