More on XLR vs RCA considerations?


Have read much about the differences between balanced vs unbalanced circuitry and the interconnects that go with it. The consensus seems to be "mostly" in favor of balanced when it is available. There are at least a few who seem to prefer unbalanced. Perhaps if the circuitry (caps etc.) becomes equal between the two, there is not much advantage to XLR? Not sure, myself. I like to have the option even though I've never used it, just makes me feel good, knowing it's there if I ever decide to use it. Long wire runs seems to be the main reason. Are there others? I heard, lowers noise floor with higher gain. OK.

I've never seen a Conrad Johnson amp or preamp with XLR connections. Maybe they exist, don't know but I've never seen it. CJ is certainly respected in the high end audio world. I'm just curious as to why they would never build with balanced circuitry. Any thoughts on why not? I'm just curious.

On short runs with well made equipment you probably won’t notice an audible difference.  I have both and choose to use XLR cables and connections when available.  The cables click or lock in place so it’s a secure connection especially with other cables around the equipment which is a benefit in my experience.  

If your equipment is True Balanced then XLR.

Otherwise I'd go unbalanced RCA.

It's where the component has isolated inputs and outputs.

There is some great information on the interweb about it. 

"None of my wire runs exceed 4 feet and most are 2 feet or less"

if pre&amp plugged into the same power outlet (or strip) in your case there will be not much difference between rca<=>xlr. balanced xlr is a must for longer connections between devices, to avoid reflections and inter-chassis-ground noise impact on single ended signal reference, which directly reduces signal to noise ratio.
