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.

Since my preamp and amp are single ended triode design, I can never use a balanced cable between them. 

?

I've never heard of a single ended triode preamp, but maybe that's just something else I've never known about until now?  @atmasphere ?  And why can't SET equipment be connected via balanced interconnects, @drbarney1 

 

Thanks @atmasphere , I am pretty stupid when it comes to understanding circuit toplology.  I was always associating SET with amps, and I was also unaware that SET amps did not normally have balanced circuits that would connect right up to the balanced outputs of a balanced (single ended) amp.  Your replies are always educational.
